Intracranial dermoid cysts occasionally rupture spontaneously into the ventricles or into the subarachnoid space. In such cases, intraventricular fat-fluid levels are invariably evident at computed tomography and may even be visible on a conventional radiograph of the skull. A case is described in which fat was observed to remain in the ventricles long after surgical removal of a dermoid cyst. We think that this fat, by causing obstruction of the cerebrospinal fluid pathways, should be regarded as a potential cause of intermittent elevation of intracranial pressure.
颅内皮样囊肿偶尔会自发破裂进入脑室或蛛网膜下腔。在这种情况下，计算机断层扫描时脑室内的脂肪 - 液平面总是很明显，甚至在颅骨常规X线片上也可能可见。本文描述了一例在手术切除皮样囊肿很久之后，仍观察到脂肪留存于脑室内的病例。我们认为，这种脂肪通过阻塞脑脊液通路，应被视为颅内压间歇性升高的一个潜在原因。
