头皮软组织肿块MSCT诊断价值

Diagnostic value of MSCT in soft tissue masses of scalp

目的探讨头皮软组织肿块的CT诊断价值。方法回顾性分析39例经手术病理证实的头皮软组织肿块病例的临床资料及CT表现,包括临床症状、发病年龄、病程、性别特点、发病部位、病变密度、边缘情况、内部情况及邻近骨质改变情况。结果 39例头皮肿块,良性30例(76.9%),恶性9例(23.1%)。良性病变类型最多见前四位依次是表皮样囊肿(14/30),皮样囊肿(5/30),钙化上皮瘤(3/30),脂肪瘤(3/30),恶性病变为角化性鳞状细胞癌(6/9)和基底细胞癌(3/9)。良性病变中伴有骨质改变3例(3/30),恶性病变中伴有骨质破坏7例(7/9),二者差异具有显著性(P<0.05)。结论 MSCT可显示头皮肿物的部位、形态及邻近骨质改变,结合肿块CT特点,可较准确判定肿块性质。

Objective To discuss the diagnostic value of MSCT in soft tissue masses of scalp. Methods CT, clinical characteristics and histological fingdings of 39 patients with soft tissue masses of scalp were analyzed retrospectively, including the clinical symptoms, age of onset, course of disease, sex, position of lesion, density of lesion, margin, internal information and adjacent destruction of bone. Results In the 39 patients, 30 were benign lesions （ 76.9% ） and 9 were malignant lesions （ 23.1% ）. Epidermoid cyst （ 14/30）, dermoid cyst （5/30）, calcifying epithelioma （3/30） and lipoma （3/30） were commonly found in benign soft tissue masses. Malignant lesions were squamous cell carcinoma （6/9） and basal cell carcinoma （3/9）. There were 3 cases （3/30） in benign lesions and 7cases （7/9） in malignant lesions with bone destruction, the difference was significant （ P 〈 0.05 ）. Conclusion MSCT can show the position, morphology of mass and adjacent destruction of bone, combined with the MSCT and clinical characteristics, we can more accurately determine the nature of the mass.
