胸壁病变的计算机X线摄影和CT检查

目的：探讨胸壁病变的计算机Ｘ线摄影（ＣＲ）和ＣＴ表现及其诊断价值，提高对胸壁病变的认识。材料和方法：回顾分析经手术病理、穿刺细胞学检查或临床随访资料证实的３９例ＣＲ和ＣＴ资料。结果：感染组１２例中（包括化脓性感染４例，胸壁结核８例），ＣＲ准确诊断４例，ＣＴ诊断１１例；软组织肿瘤组１６例中（包括脂肪瘤７例，纤维肉瘤４例，血管瘤、神经纤维瘤、恶性纤维组织细胞瘤、侵袭性纤维瘤病和脂肪肉瘤各１例），ＣＲ准确诊断３例，ＣＴ诊断１４例；骨肿瘤和肿瘤样病变组１１例中（包括骨纤维异常增殖症７例，软骨瘤２例，多发性骨髓瘤和骨嗜酸性肉芽肿各１例），ＣＲ准确诊断８例，ＣＴ诊断１０例。结论：ＣＲ简便，能诊断大多数胸壁骨性病变。ＣＴ对各种胸壁病变尤其是软组织病变的诊断较ＣＲ明显优越，对鉴别胸壁肿瘤的良恶性有肯定作用，但仍有一定限制。

Computed Radiography and Computed Tomography of Chest Wall Diseases

Purpose: To analyze competed radiography (CR) and computed tomography (CT) findings of diseases of chest wall and to investigate the value of CR and CT in diagnosis of these diseases. Materials and Methods: The findings and diagnoses of 39 cases with proved (by fina needle biopsy, or surgory and /or pathology, of clinical follow up) chest wail disease were analysed retrospectively. Resulte: In 12 infective lesions, including purulent infection (4 cases) and tuberculosis (8 cases) 3 the correct dignosis was made in 4cases by CR and in 11 cases by CT. In 16 soft tissue tumors, including lipoma (7 cases) ,fi- brosarcoma (4 cases) , hemangioma (1 case) , neurofibroma (1 case) , malignant fibrous histocytoma (1 case), aggressive fibromatosis (1 case) and liposarcoma (1 case), the correct diagnosis was made in 3 cases by CR and in 14 cases by CT. In 11 bone lesions, including fibrous dysplasia (7 cases), chondroma (2 cases), myeloma (lease) and cosinophilic granuloma (1 case), the correct diagnosis was made in 8cases by CR and in 10 cases by CT. Conclusion: CR is useful in the dignosis of chest wall bone diseases. CT is obviously superior to CR for demonstration of ail chest wall diseases espacially for soft tissue lesions. CT has definite value for the differentiation of mallgnant from benign tumors of chest wall, but still has certain limit.
