The authors describe a case of xanthofibroma of the skull. A 53-year-old female was admitted to our hospital in September, 1991, with subarachnoid hemorrhage due to a ruptured aneurysm of the anterior communicating artery. The roentgenogram of her skull incidentally revealed the presence of a radiolucent (a punched out) lesion of about 20 x 25 mm in the right occipital bone. On computed tomography (CT), the mass was seen to be mainly localized in the diploe, and the outer table of the skull was thinned. On both T1 and T2 weighted magnetic resonance image (MRI), the mass showed a high intensity signal equivalent to that found in adipose tissue. The bony tumor was totally removed. Histology revealed a collection of foamy cells, benign fibrous tissues and so on which led to a diagnosis of xanthofibroma of the skull without hyperlipidemia. Xanthofibroma of the skull is extremely rare. To our knowledge, including our case, only three cases have been reported.
作者描述了一例颅骨黄色纤维瘤病例。一名53岁女性于1991年9月因前交通动脉瘤破裂导致蛛网膜下腔出血入住我院。她的颅骨X线片偶然发现右枕骨有一个约20×25mm的透光（筛孔状）病变。在计算机断层扫描（CT）上，肿块主要位于板障，颅骨外板变薄。在T1加权和T2加权磁共振成像（MRI）上，肿块均显示出与脂肪组织相同的高强度信号。骨肿瘤被完全切除。组织学检查显示有泡沫细胞、良性纤维组织等聚集，从而诊断为无高脂血症的颅骨黄色纤维瘤。颅骨黄色纤维瘤极为罕见。据我们所知，包括我们的病例在内仅有3例报道。
