Fahr's syndrome and optic nerve head calcification in young: A rare consortium

Abstract

Fahr's syndrome, a rare disease, is characterized by symmetrical and bilateral intracranial calcification. Here, we present the case of a 25-year-old female. She presented with progressive diminution of vision, dysarthria, and slowness of movements and had a history of seizures. Neurological examination revealed Parkinsonian features and episodes of stiffness all over the body. Right eye ultrasound-B scan and swept-source optical coherence tomography revealed optic nerve head (ONH) calcification, which is not a common finding. A computed tomography scan of the brain revealed bilateral, symmetrical, large areas of calcification over the basal ganglia, thalamus, and globus pallidus. In our patient, age and ONH calcification were two uncommon presentations.
