Spontaneous pure acute bilateral subdural haematoma (ASDH) without intraparenchymal or subarachnoid haemorrhage caused by a ruptured cerebral aneurysm is extremely rare. It can follow rupture of different aneurysms specially located in anterior incisural space; the most frequently encountered location is the PcoA aneurysms as demonstrated in the present case. We present a case report of a PcoA aneurysm presenting as pure bilateral ASDH. A high level of suspicion for bleeding of arterial origin should be maintained in all cases of acute subdural haematoma without history of trauma. The neurological status on admission dictates the appropriate timing and methodology of the neuroradiological investigations.
由脑动脉瘤破裂引起的无脑实质内或蛛网膜下腔出血的自发性单纯急性双侧硬膜下血肿（ASDH）极为罕见。它可继发于特殊位于前切迹间隙的不同动脉瘤破裂；如本病例所示，最常遇到的位置是后交通动脉瘤（PcoA）。我们报告一例表现为单纯双侧ASDH的PcoA动脉瘤病例。对于所有无外伤史的急性硬膜下血肿病例，都应高度怀疑动脉源性出血。入院时的神经状态决定了神经放射学检查的合适时机和方法。
