腹壁肿瘤及瘤样病变的CT 诊断（附44 例报道）

目的:分析腹壁肿瘤及瘤样病变的CT表现,旨在提高医师对腹壁肿瘤及瘤样病变的认识,并评价CT在腹壁肿瘤诊断及鉴别诊断中的价值。方法:回顾性分析44例经病理证实的腹壁肿瘤及肿瘤样病变的CT表现,并与病理结果对照。结果:(1)CT扫描对腹壁肿瘤及瘤样病变的定位诊断率达到100%(44/44),定性诊断率约84.1%(37/44)。(2)良恶性病变在边界清晰与否、大小等方面并没有差异,边界不清的29例病例中,14例为良性,15例为恶性。(3)腹壁病变呈较高密度影者均为良性(7/7),血管源性多见。(4)血管瘤、纤维肉瘤、韧带样纤维瘤亦为渐进性强化,腹壁脓肿、结核为环状强化,转移瘤为不均匀强化。结论:CT是目前诊断腹壁肿瘤及肿瘤样病变的主要手段,能较准确定位病变,但对病变定性仍有一定的困难,最终需要病理证实。

CT Diagnosis of Tumors or Tumor-like Lesions of Abdominal Wall(Report of 44 Cases)

Objective: To study the imaging findings of tumors and tumor-like lesions of abdominal wall in order to evaluate the role of CT in diagnosis of it.Methods: Analyze the clinical presentations and imaging presentation in 44 cases with review of the literature,and contrast it with the Pathological findings.Results:(1) The niveau diagnosis ratio of CT to the tumors and tumor-like lesions of abdominal wall reach 100%,and qualitation diagnosis ratio is 84.1%.(2) There is no discrepancy between benign and malignant disease in the size and the boundary.There are 29 ill-defined cases,14 cases are benign,15 cases are malignant.(3) All the high density lesions in the abdominal wall are benign(7/7).(4)Angeioma and desmoid tumor manifest gradual enhancement,mural abscess and tuberculosis manifest crico-enhancement,so malignant tumor such as fibrosarcoma and metastatic tumor manifest uneven enhancement.Conclusion: CT plays an important role in the diagnosis,staging and curative effect inspecting of tumors and tumor-like lesions of abdominal wall,but it is difficult to qualitation,so the pathological findings is the extreme diagnosis.
