摘要
目的总结头皮良恶性软组织肿块的临床表现与CT特点,提高鉴别诊断能力。方法回顾性分析32例经手术病理证实的头皮软组织肿块病例临床资料及CT表现。结果良性肿块23例(71.9%),恶性9例(28.1%)。临床表现:恶性肿块破溃(77.8%)、瘙痒(100%)、生长快(77.8%)、基础病史(66.7%)发生率均明显高于良性肿块(43%、8.7%、34.8%、4.3%),且差异具有显著性(P<0.05);良性肿块(73.9%)较恶性肿块(22.2%)具有更好的移动度(P<0.05)。良恶性肿块均可出现疼痛症状(P>0.05)。CT特点:良性肿块多为囊实性或囊性(78.3%)、有完整包膜(95.7%)、边界清楚(95.7%)、形态规则(100%)、多数无骨质破坏(82.6%),恶性肿块呈实性(100%)、无包膜(88.9%)、边界不清(77.8%)、形态不规则(88.9%)、有骨质破坏(55.6%),上述特点良恶性肿块发生率差异具有显著性(P<0.05);良恶性肿块钙化发生率均较低(P>0.05)。结论良恶性头皮软组织肿块具有较特征的临床表现与CT特点。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 sum up the clinical features and CT features of benign and malignant scalp soft tissue masses, and to improve the ability of differential diagnosis. Methods CT, clinical characteristics and histological fingdings of 32 patients with soft tissue masses of scalp were analyzed retrospectively. Results 23 were benign lesions （71.9%） and 9 were malignant lesions （28.1%）. Clinical manifestation：the occurrence rate of malignant tumor （77.8%） , pruritus （ 100% ） , rapid growth （77.8%） and basic medical history （66.7%） were significantly higher than those of benign masses （8.7% , 34.8% , 4.3% , 4.3% ） , and the difference was significant （ P 〈 0.05 ） ; Benign masses （73.9%） had better mobility than those of malignant masses （22.2%）. Benign and malignant tmnors can be found in pain symptoms （ P 〉 0.05 ）. CT features：the benign masses were cystic solid or cystic （78.3%） , complete capsule （95.7%） , clear boundary （95.7%） , form rule （100%） , and no bone destruction （82.6%）. The malignant tumors were solid （ 100% ） , no capsule （ 88.9% ） , unclear boundary （77.8%） , irregular shape （88.9%） , and bone destruction （55.6%）. The difference of occurrence rate of benign and malignant tumors was significant （ P 〈 0.05 ） , and the incidence of calcification in benign and malignant tumors was lower （ P 〉 0.05 ）. Conclusion Benign and malignant scalp soft tissue masses have typical clinical manifestations and CT features. 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.
