A case of intracranial epidermoid cyst with intracystic hemorrhage is reported. A 63-year-old woman sustained a head injury after a fall; obtundation and ataxia were noted later. Computed tomography revealed a heterogeneous hyperdense lesion in the posterior and middle cranial fossas. Magnetic resonance imaging showed a lesion with increased signal intensity both on T1 and T2 weighted images. Two craniotomies revealed an intracranial epidermoid cyst with about 6 mL of clotted blood. Pathologic study showed hemosiderin-laden macrophages and neovascularity in the cystic wall granulation tissue, which indicated rupture of the cystic wall with intracystic hemorrhage, which later correlated with the diagnostic image findings. The patient tolerated the two operations well and her postoperative course was smooth. She was discharged in good health without obvious neurologic deficits.
报告1例颅内表皮样囊肿合并囊内出血的病例。一名63岁女性跌倒后头部受伤；随后出现意识模糊和共济失调。计算机断层扫描显示颅后窝和颅中窝有一个不均匀的高密度病变。磁共振成像显示在T1加权像和T2加权像上病变信号强度均增加。两次开颅手术发现一个颅内表皮样囊肿，伴有约6 mL凝血。病理研究显示囊壁肉芽组织中有含铁血黄素巨噬细胞和新生血管，这表明囊壁破裂并伴有囊内出血，这与诊断性影像结果相符。患者对两次手术耐受良好，术后病程顺利。她健康出院，无明显神经功能缺损。
