Intracranial hypotension has been associated with a wide spectrum of neurological conditions including chronic non-aneurysmal and acute aneurysmal subarachnoid hemorrhage.
A 59-year-old man presented with a non-aneurysmal subarachnoid hemorrhage in a perimesencephalic pattern after a mild physical exertion. In the course of the disease, a magnetic resonance imaging of head and spine displayed intracranial hypotension that resolved spontaneously.
Long-standing intracranial hypotension has been reported as the cause of chronic subarachnoid hemorrhage and a single case of intracranial hypotension as the consequence of intracranial pressure fluctuations after acute aneurysmal subarachnoid hemorrhage has been described. This is the first description of intracranial hypotension caused by acute non-aneurysmal subarachnoid hemorrhage. We hypothesize that blood in the subarachnoid space could have determined a spine cerebrospinal fluid leak through intracranial pressure fluctuations or mechanical action, causing arachnoiditis and possibly a dural tear.
颅内低血压与广泛的神经系统疾病相关，包括慢性非动脉瘤性和急性动脉瘤性蛛网膜下腔出血。
一名 59 岁男性在轻度体力活动后出现中脑周围模式的非动脉瘤性蛛网膜下腔出血。在疾病过程中，头部和脊柱的磁共振成像显示颅内低血压，自发性缓解。
据报道，长期颅内低血压是慢性蛛网膜下腔出血的原因，而颅内压波动后急性动脉瘤性蛛网膜下腔出血导致颅内低血压的单一病例也有描述。这是颅内低血压由急性非动脉瘤性蛛网膜下腔出血引起的首例描述。我们假设蛛网膜下腔中的血液可能通过颅内压波动或机械作用导致脊柱脑脊液漏，引起蛛网膜炎并可能导致硬脑膜撕裂。
