A case of occipital tumor simulating sinus pericranii was reported. The patient was a 4-year-old girl who suffered from headache and nausea following head injury on midoccipital tumor, but had no remarkable neurological deficit. Her occipital tumor was soft, compressible redish and cyst-like without bruit. Conray cystography of this tumor showed superior sagittal sinus like shadow (Fig. 4). Total removal of the tumor associated with epidural hematoma was performed. Histologically this tumor was confirmed as eosinophilic granuloma. Pathogenesis of this case is following, since patient's tumor was blowed, intratumor-bleeding occurred cosequently and the bleeding flowed into epidural space. So the tumor simulated sinus pericranii (Fig. 5.).
报告了一例模拟颅骨膜窦的枕部肿瘤病例。患者为一名4岁女孩，枕部中部肿瘤受伤后出现头痛和恶心，但无明显神经功能缺损。她的枕部肿瘤质地柔软，可压缩，呈红色，类似囊肿，无杂音。该肿瘤的康瑞造影显示上矢状窦样阴影（图4）。进行了与硬膜外血肿相关的肿瘤全切术。组织学检查证实该肿瘤为嗜酸性肉芽肿。该病例的发病机制如下，由于患者的肿瘤受到撞击，继而发生肿瘤内出血，血液流入硬膜外间隙。因此该肿瘤模拟了颅骨膜窦（图5）。
