摘要
目的:探讨头皮外毛根鞘癌(TLC)的MRI表现和病理组织学特点,提高对TLC的认识。方法:结合文献复习,回顾性分析1例经病理证实的TLC影像学表现、病理组织学特点、治疗及预后。结果:TLC的MRI表现以等/长T1信号,等/长T2信号为主,内见散在斑片状更长T1更长T2坏死、囊变区,表面可见溃疡形成,可侵袭、破坏邻近颅板,手术切除后少复发或转移。结论:深入了解TLC的MRI表现和病理组织学特点,对TLC的诊断、治疗和预后具有重要价值。
Objective：To explore the MRI appearance and histopathological characteristics of tricholemmal carcinoma （TLC）,and to improve the understanding of TLC.Methods：The data of a case of TLC proved by pathology in our hospital were analyzed retrospectively and the MRI appearance,histopathological characteristics,treatment and prognosis about TLC were summarized with reference to literature review.Results：MRI appearance of TLC was dominated by low-or/and iso-signal intensity on T1WI and by iso-or /and hyper-signal intensity on T2WI.Scattered pathy necrosis and cystic area in the lesion and ulcer on the lesion surface could be seen.TLC could invade and damage adjacent bones of skull.Recurrence or metastasis rarely occurred after the surgical resection.Conclusion：Further study of the characteristics in MRI and histopathology of TLC is of great value to the diagnosis,treatment and prognosis for TLC.
