Abstract

Superficial siderosis (SS) in central nervous system is a rare, slowly progressive disease and usually misdiagnosed or diag- nosed 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 he- mosiderin 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 am - biguous. Serial follow-up of imaging study and education for patient are necessary to prevent progression of SS. (Korean J Neurotrauma 2013;9:139-141)
