A single and perhaps unique case of a venous malformation over the quadrigeminal plate causing acute obstructive hydrocephalus is reported. The lesion was well demonstrated by means of CAT scan but cerebral angiography failed to reveal the vascular nature of this lesion. Complete thrombosis of the lesion was achieved by surgical intervention and the resolution of the lesion was demonstrated by CAT scan. The patient remains asymptomatic and neurologically intact six months after the operation.
报告了一例位于四叠体板上的静脉畸形导致急性梗阻性脑积水的病例，这可能是唯一的此类病例。通过计算机断层扫描（CAT）很好地显示了该病变，但脑血管造影未能揭示该病变的血管性质。通过手术干预实现了病变的完全血栓形成，并且CAT扫描显示了病变的消退。术后六个月，患者仍无症状，神经功能完好。
