The disease most often includes a movement disorder, cognitive decline, and typical magnetic resonance imaging (MRI) appearance. This disease develops from mutations in the ferritin light chain gene (FTL1) [<xref ref-type="bibr" rid="B1">1</xref>]. Seven known mutations of this gene have been discovered [<xref ref-type="bibr" rid="B2">2</xref>]. The resulting mutations alter the reading frame and disrupt the ferritin light chain polypeptide's tertiary structure, leading to inappropriate release from ferritin polymers [<xref ref-type="bibr" rid="B3">3</xref>]. These effects are primarily seen in the central nervous system. The resulting mutations will cause a low serum ferritin level in most patients [<xref ref-type="bibr" rid="B2">2</xref>].</p><p>A variety of abnormal, involuntary movements is demonstrated in the clinical presentation of neuroferritinopathy. Published clinical descriptions include orofacial dyskinesia, focal dystonia, chorea, finger and toe stereotypies, parkinsonism, and tremors [<xref ref-type="bibr" rid="B1">1</xref>, <xref ref-type="bibr" rid="B4">4</xref>, <xref ref-type="bibr" rid="B5">5</xref>, <xref ref-type="bibr" rid="B6">6</xref>]. Although it is an autosomal disease, phenotypic variations have been described [<xref ref-type="bibr" rid="B1">1</xref>]. In contrast to other NBIA disorders, pigmentary retinopathy and acanthocytosis have not been reported in neuroferritinopathy [<xref ref-type="bibr" rid="B2">2</xref>].</p><p>Abnormalities seen on MRI initially include iron deposition, and subsequently edema, gliosis, cystic changes, and cortical atrophy [<xref ref-type="bibr" rid="B1">1</xref>, <xref ref-type="bibr" rid="B4">4</xref>]. Central nervous system iron deposition occurs with normal aging, especially in the globus pallidus, putamen, substantia nigra, and dentate. Patients affected with neuroferritinopathy demonstrate iron and ferritin deposits in excess of expected age-related accumulation, most prominently within the basal ganglia [<xref ref-type="bibr" rid="B1">1</xref>, <xref ref-type="bibr" rid="B5">5</xref>]. Cystic changes are most often pronounced within the globus pallidus and putamen [<xref ref-type="bibr" rid="B2">2</xref>], but may occur in the thalamus, dentate, and caudate [<xref ref-type="bibr" rid="B1">1</xref>, <xref ref-type="bibr" rid="B4">4</xref>]. Sometimes MRI also demonstrates cortical atrophy, both within the cerebellum and cerebral cortices [<xref ref-type="bibr" rid="B2">2</xref>]. Overall, there is a progression of MRI changes from T2 hypointensities due to iron deposition to T2 hyperintensities likely caused by the start of cystic degeneration. Here, we present a late-onset case, along with diffusion tensor imaging (DTI).</p></sec><sec id="sec1_2"><title>Case Presentation</title><p>A 74-year-old, right-handed Caucasian female presented for evaluation of involuntary mouth movements. Her teeth had been removed 15 years ago and were replaced with dentures. Initially, there were no involuntary movements of the mouth or tongue. She had stopped wearing dentures 5 years prior to presentation, secondary to cost for replacement dentures. Over the past few years, she reported a progressively worsening mouth and tongue dyskinesia, which became bothersome about 1 year ago. She complained that eating would worsen these dyskinesias and, on some occasions, food would fall out of her mouth. She denied any other abnormal movements throughout the rest of her body except for occasional toe movements that would occur bilaterally and involuntarily. The patient also complained of a mildly unsteady gait during the past year. Her previous medical history was significant for anxiety. We cannot rule out a family history as she last had contact with her father when he was 38 years old.</p><p>Neurologically, she had no evidence of tremor, myoclonus, or dystonia. There was, however, continuous orofacial dyskinesia (see supplementary <xref ref-type="supplementary-material" rid="S2">video</xref>). In the setting of her ill-fitted dentures, this was initially believed to be edentulous dyskinesia [<xref ref-type="bibr" rid="B7">7</xref>, <xref ref-type="bibr" rid="B8">8</xref>]. She also had persistent stereotypic movements of her hands and feet bilaterally. Additionally, there was motor impersistence as the patient was unable to protrude her tongue for longer than 6 s. On cranial nerve testing, the patient demonstrated saccadic pursuit and mild delay in saccade initiation. Her gait was somewhat wide-based but with normal initiation, arm swing, and stride length. The remainder of her exam was noncontributory and without any deficits in motor or sensory examination.</p><p>A detailed history was taken, including all medications the patient had received in her lifetime. The patient denied ever being on any type of neuroleptics or antipsychotic medications, including haloperidol. Given that the patient presented with saccadic dysfunction as well as bilateral extremity sterotypies, a broad differential diagnosis of hyperkinetic movement disorders was considered. The patient was sent for a CT scan in search of hyperdense calcifications due to the phenotypic similarity of Fahr's Syndrome. In addition, MRI along with DTI scans were performed.</p></sec><sec sec-type="results" id="sec1_3"><title>Results</title><p>A review of her complete blood count demonstrated no acanthocytes, excluding chorea-acanthocytosis [<xref ref-type="bibr" rid="B9">9</xref>]. Given imaging and clinical features discussed below, neuroferritinopathy was considered. Serum ferritin is a useful initial test for neuroferritinopathy since it is usually low in these patients. The ferritin level in our patient was 50 μg/l. A recent review of all published cases of neuroferritinopathy noted that after using a cutoff of 30 μg/l, 64% of the males and 84% of the females had low ferritin levels. Presence of low ferritin is not necessary in the diagnosis of neuroferritinopathy [<xref ref-type="bibr" rid="B10">10</xref>].</p><p>Hypodensities consistent with iron deposition instead of expected hyperdensities from calcium deposits in Fahr's syndrome were seen in bilateral basal ganglia on a head CT (online suppl. <bold>fig. <xref ref-type="supplementary-material" rid="S1">1</xref></bold>; for all online suppl. material, see <ext-link ext-link-type="uri" xlink:href="http://www.karger.com/doi/10.1159/000345871">www.karger.com/doi/10.1159/000345871</ext-link>). The combination of a T2 hypointense rim and T2 hyperintense center of the globus pallidus (eye-of-the-tiger sign) was present bilaterally (fig. <xref ref-type="fig" rid="F1">1</xref>). T2 hypodensity of the putamen was also present. Sequences of the midbrain showed a hypointense substantia nigra and red nucleus. A black and white fractional anisotropy (FA) map showed areas of increased anisotropy in the substantia nigra (<bold>fig. <xref ref-type="fig" rid="F2">2</xref></bold>). Analogous findings were seen in the dentate nucleus with a T2 hypointense lateral portion and a T2 hyperintense medial portion, along with increased anisotropy on the FA map within the dentate nucleus (<bold>fig. <xref ref-type="fig" rid="F3">3</xref></bold>).</p><sec id="sec2_2"><title>Differential Diagnosis</title><p>Given evidence of abnormal iron depositions seen on MRI corroborated by hypodensities seen on the patient's CT scan, NBIA was considered. Perhaps the best-known disorder among these is pantothenate kinase-associated neurodegeneration (PKAN/NBIA1), formerly known as Hallervorden-Spatz disease in typical young-onset cases and Hallervorden-Spatz syndrome in atypical late-onset cases. Typical PKAN is an early-onset movement disorder due to mutation of the PANK2 gene [<xref ref-type="bibr" rid="B11">11</xref>]. Clinically, individuals present with progressive pigmentary retinopathy, severe dystonia, and sometimes with neuropsychiatric features or cognitive decline. Interestingly, acanthocytes may be seen in PANK2. Brain MRI findings include a hypointense outer rim with central hyperintensity of the globus pallidus on T2 and T2* sequences, known as the eye-of-the-tiger sign [<xref ref-type="bibr" rid="B12">12</xref>]. Although thought to be pathognomonic for the PANK2 mutation, the eye-of-the-tiger sign was documented in neuroferritinopathy as well as atypical PKAN [<xref ref-type="bibr" rid="B12">12</xref>, <xref ref-type="bibr" rid="B13">13</xref>, <xref ref-type="bibr" rid="B14">14</xref>]. Our patient clearly demonstrated this sign, but lacked certain other characteristics typical of PKAN. In most PKAN cases, T2 changes are present only in the globus pallidus and substantia nigra [<xref ref-type="bibr" rid="B2">2</xref>]. Our patient's lesions were widespread, and along with late onset, lack of progressive pigmentary retinopathy, or severe dystonia, a diagnosis of PKAN was not pursued further.</p><p>Although the patient did not demonstrate a low serum ferritin level that would have been more consistent with neuroferritinopathy, her MRI changes along with her presentation of orofacial dyskinesias, upper and lower extremity stereotypies, and lack of pigmentary retinopathy led us to a diagnosis of neuroferritinopathy (NBIA3). There was evidence of iron deposition outside the globus pallidus and substantia nigra, namely in the putamen, red nucleus, and lateral dentate, seen as T2 hypointense areas. In addition, medial dentate T2 hyperintensity due to cystic degeneration supported neuroferritinopathy.</p><p>Another NBIA disorder, aceruloplasminemia, clinically manifests by iron accumulation in the brain, liver, and reticuloendothelial system [<xref ref-type="bibr" rid="B2">2</xref>]. Ceruloplasmin gene mutation leads to abnormal iron deposition in this disease [<xref ref-type="bibr" rid="B15">15</xref>]. These patients can present with cerebellar ataxia, chorea, facial grimacing, and progressive dementia. There are also cases reported that link this disorder to the development of diabetes mellitus given the widespread iron deposition throughout the body [<xref ref-type="bibr" rid="B15">15</xref>]. Iron was not detected in other organs in our patient. MRI findings demonstrated iron deposition in the entire basal ganglia along with thalamic involvement seen on T2 and T2*, compared to neuroferritinopathy in which 15% of cases are reported to have all nuclei involved, and none with thalamic abnormalities [<xref ref-type="bibr" rid="B2">2</xref>, <xref ref-type="bibr" rid="B12">12</xref>]. Without the classic clinical picture, along with the absence of thalamic involvement on MRI, aceruloplasminemia was not considered consistent with our patient's condition.</p><p>Neuroaxonal dystrophy (NAD/NBIA2) has been well described and attributed to mutations in the calcium-independent phospholipase A2 gene PLA2G6. It was initially seen as a disease found in infancy, but there have been individuals who were thought to have idiopathic NBIA with the PLA2G6 mutation [<xref ref-type="bibr" rid="B16">16</xref>]. Symptoms in NAD are consistent with severe hypotonia, ataxia, dystonia, and, most notably, peripheral neuropathy.</p><p>A recent addition to the NBIA group of disorders is fatty acid hydroxylase-associated neurodegeneration (FAHN), which is a result of mutations in the fatty acid-2 hydroxylase FA2H gene [<xref ref-type="bibr" rid="B17">17</xref>]. Patients are usually affected earlier in life compared to neuroferritinopathy patients and present with spastic quadriparesis, ataxia, and dystonia [<xref ref-type="bibr" rid="B17">17</xref>]. MRI demonstrates of iron accumulation with T2 hypointensities in the globus pallidus and pontine, cerebellar atrophy as well as T2 white matter hyperintensities [<xref ref-type="bibr" rid="B17">17</xref>].</p><p>Another novel NBIA syndrome, Woodhouse-Sakati Syndrome (WSS), has been described and is the result of a single base pair deletion in the c2orf37 gene [<xref ref-type="bibr" rid="B18">18</xref>]. Most cases have been reported from families of Middle Eastern origin. Symptoms include diabetes mellitus, choreoathetosis, and dystonia [<xref ref-type="bibr" rid="B19">19</xref>]. The hallmark feature of this disease is alopecia. MRI studies demonstrate globus pallidus T2 hypointensities consistent with the NBIA group of disorders [<xref ref-type="bibr" rid="B18">18</xref>]. To our knowledge, there has been no eye-of-the-tiger sign seen on MRI in either FAHN or WSS. Because our patient presented later in life, without pontocerebellar atrophy and complaints of alopecia, a diagnosis of either FAHN or WSS was not supported. Juvenile amyotrophic lateral sclerosis presentation of NBIA due to c19orf12 mutation (NBIA4) was not considered [<xref ref-type="bibr" rid="B20">20</xref>].</p></sec></sec><sec sec-type="discussion" id="sec1_4"><title>Discussion</title><p>The approach to the patient's diagnosis was stepwise in fashion, and we believe this allowed us to come to the proper diagnosis. The patient's initial symptoms were consistent with edentulous dyskinesia secondary to ill-fitting dentures. With regard to her other extrapyramidal findings, a CT scan was indicated due to concerns about Fahr's disease. The CT scan, however, demonstrated a surprisingly different picture given the hypodensities seen. This led us to request the MRI that demonstrated the eye-of-the-tiger sign along with the multiple T2 changes noted above. The eye-of-the-tiger sign can lead to a diagnosis of PKAN, but as mentioned, this sign is no longer pathognomonic for the PANK2 gene and has been previously described in neuroferritinopathy.</p><p>MRI imaging reveals multiple stages of neuroferritinopathy. When T2* imaging is performed with a gradient echo sequence, the results are very sensitive to changes in paramagnetism that is seen with iron deposition [<xref ref-type="bibr" rid="B2">2</xref>]. Hence, initial MRI changes are observed with T2* imaging as hypointensities within the basal ganglia. On T2 conventional imaging, minor low-signal hypointensity is seen [<xref ref-type="bibr" rid="B21">21</xref>]. As the disease progresses, the T2* signal loss and the T2 hypointensity become more pronounced. Eventually, the cerebral cortex, thalamus, substantia nigra, red and dentate nuclei become involved [<xref ref-type="bibr" rid="B2">2</xref>]. The next clinical stage of neuroferritinopathy demonstrates a change to T2 hyperintensities as there will be changes in water content secondary to edema and gliosis. This change is thought to be precystic in origin [<xref ref-type="bibr" rid="B22">22</xref>]. At advanced stages of neuroferritinopathy, there are characteristic symmetrical basal ganglia T1 hypointense and T2 hyperintense regions consistent with cystic degeneration [<xref ref-type="bibr" rid="B21">21</xref>].</p><p>Treatment for neuroferritinopathy has not been well established. Iron chelating agents have been tried due to the accumulation of iron, but they have not been found to be efficacious. A recent review of all therapies listed in case reports [<xref ref-type="bibr" rid="B10">10</xref>] demonstrated that 14/15 patients received benefit from tetrabenazine. Lehn et al. [<xref ref-type="bibr" rid="B10">10</xref>] also found that benzodiazepines, botulinum toxin chemodenervation, anticholinergics, and muscle relaxants, including baclofen, might be beneficial for symptomatic therapy. Unfortunately, our patient did not respond to the use of amantadine. We were unable to prescribe tetrabenazine secondary to cost. Reserpine, a dopamine depleter which may have provided relief, is no longer available in the USA or Canada. Given her history of visual hallucinations, anticholinergics were avoided.</p></sec><sec sec-type="conclusions" id="sec1_5"><title>Conclusion</title><p>Neuroferritinopathy is an autosomal dominant neurodegenerative disorder that is grouped within the family of disorders designated NBIA. The disease will most often include a movement disorder, cognitive decline, and typical MRI appearance. Movements include orofacial dyskinesia, focal dystonia, chorea, finger and toe stereotypies, parkinsonism, and tremors. MRI studies demonstrated a progression from T2 hypointensities due to iron deposition to T2 hyperintensities likely caused by the start of cystic degeneration. Serum ferritin levels can be low, but this is not pathognomonic for this disease. Treatment is limited but there has been good response to tetrabenazine.</p></sec><sec id="sec1_6"><title>Disclosure Statement</title><p>Dr. Fekete received honoraria from Medlink, Inc., and serves as
