Abstract
Calcification of basal ganglia is known as FAHR’s syndrome or FAHR’s disease. It’s a rare phenomenon which generally affects the young to middle aged adults. A 39-year-old female was sent to the radiology department of Sree Balaji Medical College, Chennai for computed tomography (CT) as she had a fall and injured her forehead. An axial plain CT scan without contrast was advised and performed. The CT study revealed mild frontal peri cranial swelling and calcification of dentate nucleus, basal ganglia, central semiovale and frontoparietal subcortical white matter was observed. On examination, however patient did not present with any other movement disorders.
Highlights
FAHR’s disease or FAHR’s syndrome is a rare, neurological disorder characterized by abnormal calcified deposits in various areas of brain
Bilateral calcification of basal ganglia, progressive neurological dysfunction, absence of an infectious, traumatic or toxic cause and a notable family history are some of the diagnostic criteria for FAHR’s disease which have been formulated based on the modifications from previous evidences
The minimum cranial calcification characterizes FAHR’s disease age at which a negative computed tomography (CT) scan can suggest the with a predilection for the basal ganglia and the exclusion of the disease has not been established as dentate nuclei
