目的：探讨M RI在诊断皮样囊肿癌变中的应用价值。方法均经手术治疗及病理证实的5例患者中，3例为女性，2例为男性，年龄38～68岁。回顾性分析5例患有皮样囊肿癌变患者的M RI表现、术前及术后、病理资料，5例患者中，3例为女性，2例为男性，年龄38‐68岁。并对其M RI表现特征进行观察总结。结果 M RI表现主要为圆形或类圆形囊实性混杂信号影，有包膜，病灶周围水肿明显，注入Gd‐DTPA后，病灶实性部分明显强化，包膜强化，相应脑膜亦强化；肿块相应周围骨质不同程度受侵。5例患者均经手术治疗及病理证实。结果：5例患者均术后复发，其中，2例患者术后约6个月复发，再次手术后，约1年复发；1例患者术后复发并死于肿瘤转移；1例患者术后复发死于颅内水肿脑疝；1例患者术后约1年复发至今存活。结论皮样囊肿癌变发病率较低，如确诊需要免疫组化及组织病理学检查结果；而磁共振在此病诊断中主要发现病变大小、形态及相应周围组织的受侵状况和在判断有无淋巴结转移上有很大的诊断意义。

Objective To explore the application value of MRI in the diagnosis of the canceration of the cranial dermoid cyst .Methods Among 5 patients with the canceration of the cranial dermoid cyst ,who were operated and confirmed by pathology ,2 patients were male and 3 female ,and the age ranged from 38 to 68 years old .The MRI and pathological char‐acteristics of 5 patients were rtetrospectively analyzed .Results The lesions were round or similar round and presented cystic‐solid mixed signal intensity with capsule and edema in the surrounding area .After injection of Gd‐DTPA ,the solid part and the capsule of the mass and the surrounding dura mater were obviously enhanced .The local bone of skull was in‐volved in different extent .The recurrence of the tumor took place in all 5 patients after the operation .The recurrence hap‐pened in 2 of 5 patients 6 months after the operation and once more recurrence 1 year after the second operation .One pa‐tient died of the recurrence and metastasis of the tumor after the operation and 1 patient died of the cerebral edema and her‐nia from the recurrent tumor after the operation .Another patient had a recurrence of the tumor and was still alive 1 year after the operation .Conclusion The canceration of the cranial dermoid cyst should be confirmed by immunohistochemistry and histopathology .M RI can present the size ,shape and involvement of the surrounding tissue and there is an important significance in the judgement of the metastasis of the tumor .
