Superficial Siderosis in Central Nervous System: A Case Report and Literature Review / 대한신경손상학회지

ABSTRACT

Superficial siderosis (SS) in central nervous system is a rare, slowly progressive disease and usually misdiagnosed or diagnosed too late when the patient is chronically devastated. A 55-year-old man with deafness and gait disturbance for ten years was referred from otorhinologist for evaluation of brain. Magnetic resonance image (MRI) showed symmetric hypointense rim partially delineated the bilateral hemisphere on gradient-recalled-echo T2-weighted image, and it was diagnosed as hemosiderin deposition in subarachnoid and subpial meningeal layer. The correct diagnosis of cerebral superficial siderosis can be achieved by careful neurological examination and MRI because computed tomography findings and symptoms are ambiguous. Serial follow-up of imaging study and education for patient are necessary to prevent progression of SS.
