Aneurysmal bone cyst (ABC) of the temporal bone is rare. The nature of the underlying disorder that converted into the ABC might, however, be difficult to ascertain on imaging as well as on histopathology. The unusual CT and MRI findings in a case of ABC of the temporal bone are presented. This had transdural intracerebral spread with a large component of solid enhancing matrix but no peripheral calcific rim. The patient was an adult of 45 years with a history of headache for more than 1 year.
颞骨动脉瘤样骨囊肿（ABC）较为罕见。然而，导致其转变为ABC的潜在疾病的性质，在影像学和组织病理学上可能都难以确定。本文展示了一例颞骨ABC的不寻常CT和MRI表现。该病例存在经硬膜的脑内扩散，有大量实性强化基质成分，但无周边钙化环。患者为一名45岁成年人，有超过1年的头痛病史。
