Superficial siderosis is a rare disease resulting from the deposited hemosiderin owing to repeated subarachnoid hemorrhage. It has been reported that hemosiderin deposits on the brain surface and brain parenchyma causes nerve disorder, resulting in progressive and irreversible hearing loss, cerebellar ataxia and pyramidal disorder. The brain tumor is one of the cause of superficial siderosis. A 16-year-old female present a nearby hospital with complaints of absence seizure. A magnetic resonance imaging (MRI) revealed a heterogeneously enhanced mass at the right temporal lobe. Susceptibility-weighted imaging revealed diffuse and extensive superficial siderosis on the brain surface. The tumor was gross totally removed and diagnosed as glioneuronal tumor. The patient had been well, although susceptibility-weighted imaging performed one year after the surgery showed superficial siderosis remained. Early diagnosis and prevention of bleeding sources are recommended to prevent symptom progression associated with superficial siderosis. Susceptibility-weighted imaging is considered useful for early detection of superficial siderosis.
