Spontaneous intracranial hypotension (SIH) is a syndrome that was unknown until the advent of magnetic resonance imaging (MRI). It is a cause of orthostatic headache, which remains underdiagnosed and, rarely, can result in several complications including dural venous sinus thrombosis, subdural hematoma and subarachnoid hemorrhage. Some of these complications are potentially life-threatening and should be recognized promptly, mainly by imaging studies. We reviewed the MRI of nine patients with SIH and describe the complications observed in three of these patients. Two of them had subdural hematoma and one had a dural venous sinus thrombosis detected by computed tomography and MRI. We concluded that MRI findings are of great importance in the diagnosis of SIH and its complications, which often influence the clinical-surgical treatment of the patient.
自发性颅内低压（SIH）是一种直到磁共振成像（MRI）出现才为人所知的综合征。它是直立性头痛的一个病因，目前仍诊断不足，且很少会导致包括硬脑膜静脉窦血栓形成、硬膜下血肿和蛛网膜下腔出血在内的多种并发症。其中一些并发症可能危及生命，主要应通过影像学检查及时识别。我们回顾了9例SIH患者的MRI检查结果，并描述了其中3例患者观察到的并发症。其中2例有硬膜下血肿，1例经计算机断层扫描和MRI检查发现有硬脑膜静脉窦血栓形成。我们得出结论，MRI检查结果对SIH及其并发症的诊断非常重要，这往往会影响患者的临床手术治疗。
