[A case with superficial siderosis of the central nervous system accompanied by sensory high tone hearing loss and recurrent headache and vomiting].
A 13-year-old boy with superficial siderosis of the central nervous system was reported. There were many members, including the proband, with sensory high tone hearing loss in his maternal family, but they did not have other neurological symptoms. Paroxysmal and pulsatile severe headache, and vomiting without aura appeared recurrently at the age of 8. His consciousness was alert and no other abnormal sign or symptom was seen during the attacks. The electroencephalogram and cranial computed tomogram revealed no abnormality. The T2 weighted magnetic resonance image of the cranium showed a superficial low intensity zone on the cerebellar vermis, frontal and parietal lobes of the cerebrum, and cervical and upper portion of the thoracic spinal cord at the age of 12, when he had severe headache and vomiting. Cerebrospinal fluid showed xanthochromia with mild elevation of the protein level during an attack, and a light bloody appearance during the asymptomatic state. The diagnosis of superficial siderosis of the central nervous system was made by these findings of magnetic resonance image and cerebrospinal fluid. The bleeding sources to the subarachnoid space could not be detected by cerebral angiography.
