 note = {A rare case of spontaneous superior sagittal sinus thrombosis occurring at 10 weeks' gestation is reported. The patient was a 28-year-old female. She had the last menstrual period 10 weeks before admission. She was admitted to our neurosurgical department because of a generalized convulsion just before admission and persistent headache, nausea, and vomiting for 1 week. On admission, neurological examination revealed left hemiparesis without disturbance of consciousness. Laboratory data showed increased fibrine degeneration products (FDP) and normal antithrombine III level. Computed tomography (CT) revealed a small intracerebral hemorrhage with perifocal linear contrast enhancement in the parietal lobe. Next day of the admission, she had left-sided clonic hemiconvulsion and gradually progressive disturbance of consciousness to be comatose. Follow-up CT revealed a large intracerebral hematoma in the right parietal lobe, the empty triangle sign of superior sagittal sinus, and the large low density areas in the bilateral parasagittal regions. Cerebral angiograms revealed occlusion of superior sagittal sinus. She was diagnosed as a spontaneous superior sagittal sinus thrombosis. A large decompressed craniectomy of the right side and a ten days' barbiturate coma therapy were performed. She became alert about 1 week after the barbiturate therapy. Although she had venous hemiplegia, she was discharged 5 months after onset without any neurological disturbances.},
