ABSTRACT
RATIONALE: Fahr syndrome is a rare, degenerative neurological condition characterized by bilateral idiopathic calcification of the periventricular region, especially the basal ganglia. This condition is often misdiagnosed as other neurological or psychiatric disorders due to its rarity and overlapping symptoms. PATIENT CONCERNS: A 34-year-old man had been experiencing seizures and cognitive dysfunction for few years, which were further compounded by slurred speech and motor difficulties as acute conditions. DIAGNOSIS: After investigations, severe hypocalcemia, and hypoparathyroidism were detected and his brain computed tomography showed extensive bilateral calcifications in basal ganglia, thalamus, dentate nuclei, and some parts of subcortical white matter, suggestive of Fahr syndrome. Although, the patient was initially misdiagnosed due to a lack of information and the rarity of this disease. INTERVENTION: The patient was treated with intravenous calcium gluconate, vitamin D3, l-ornithine l-aspartate syrup, and levetiracetam, replacing carbamazepine. OUTCOME: His symptoms, including slurred speech, muscle pain, and stiffness improved, serum calcium normalized, and he was discharged with medications for memory deficit and depression. LESSONS: This case underscores the importance of raising awareness among physicians, especially in areas with limited medical resources, about the significance of prompt diagnosis and appropriate symptomatic treatment in enhancing patient prognosis and quality of life.
