[Acute spontaneous subdural hematoma associated with multiple aneurysms--a case report].
A case of acute spontaneous subdural hematoma associated with three aneurysms is reported. On March 12, 1984, a 47-year-old woman experienced the sudden onset of severe headache over the bilateral frontal region and vomiting. Three hours later, she was transferred to our hospital by ambulance car because of continuous headache and vomiting. She had no history of head trauma. She had been medicated hypertension for five years. On admission she suffered from headache and nausea. But there was no clinical sign in physical and neurological examinations. The meningeal irritation was not present, but lumbar puncture showed slightly pinky CSF with normal pressure. A plain computed tomographic scan showed a thin high density mass in the left temporal extra-axial region and the slight deviation of the midline structures to the right. Left carotid arteriogram showed an avascular region over the left cerebral convexity, an aneurysm of the left A2-A3 junction and a questionable aneurysm of the bifurcation of left middle cerebral artery. Right carotid arteriogram showed an aneurysm of the bifurcation of right middle cerebral artery. We diagnosed this case as an acute subdural hematoma by CT scan and arteriogram. We were perplexed preoperatively whether this bleeding was spontaneous or secondary to the rupture of aneurysm, and we could not deny the possibility of a ruptured aneurysm. On March 15, 1984, three days after onset, operation was performed. At operation, a small subdural hematoma was removed, and the underlying cortex was normal.(ABSTRACT TRUNCATED AT 250 WORDS)
