颅内前颞部皮样囊肿伴皮肤窦道的诊断与治疗：附2例报告

目的：探讨颅内前颞部皮样囊肿伴皮肤窦道的诊断和治疗。方法：分析在我科治疗的2例颅内前颞部皮样囊肿伴皮肤窦道患者的病史,临床治疗经过,并复习相关文献资料进行讨论。结果：病例1,女,3岁,因右颅内脓肿而就诊。病例2,男,5岁,因右颞间隙感染就诊。2例病例右前颞部皮肤均有窦道,感染控制后行颅内外联合手术,见囊肿条索均穿过颞骨与硬脑膜粘连。病理证实为皮样囊肿。术后分别随访14个月和3个月,均无复发。结论：前颞部皮样囊肿伴皮肤窦道非常罕见,会引起脑膜炎和脑脓肿等严重并发症,治疗不当易复发。需行CT或MRI检查,且施行颅内外联合手术,才能取得满意的治疗效果。

Clinical diagnosis and treatment of intracranial frontotemporal dermoid cyst with cutaneous sinus tract: Report of 2 cases

PURPOSE： The aim of this study is to discuss the diagnosis and treatment of intracranial frontotemporal dermoid cyst with cutaneous sinus tract. METHODS： The history and process of clinical treatment of 2 cases were analyzed and the relative literatures were reviewed. RESULTS： Case 1,a girl aged 3 years presented with intracranial abscesses. Case 2, a 5-year old boy suffered from temporal space abscess. After control of infection, a combined intra-and extracranial approach was performed. There was cutaneous sinus of frontotemporal skin and fibrous sheet of dermoid extended down to the dura mater. Dermoid cyst was confirmed by pathology. No recurrence was noted after 14 months and 3 months of follow-up period, respectively. CONCLUSIONS： Intracranial frontotemporal dermoid cyst is rare and could cause severe complications such as meningitis and cerebral abscess. Successful treatment can be obtained through localization with CT scan or MRI, and combined intra-and extracranial operation.
