Abstract
We report a case of ruptured subarachnoid dermoid cyst which was explored with both CT and MRI. This rare condition results from the accumulation of a large amount of fat with a characteristic aspect at-imaging. Rupture causes fat dissemination in the subarachnoid space. In most cases, CT or MRI can provide sure diagnosis of the tumor and of rupture.
摘要
我们报告一例经CT和MRI检查的破裂蛛网膜下腔皮样囊肿病例。这种罕见情况是由于大量具有特征性影像学表现的脂肪积聚所致。破裂导致脂肪在蛛网膜下腔播散。在大多数情况下，CT或MRI能够对肿瘤及其破裂作出明确诊断。
