不典型腸系膜囊腫的CT表現(xiàn)與病理分析
[Abstract]:Objective to analyze the features and clinical features of CT in atypical mesenteric cyst (MC) in order to improve the understanding and diagnosis of the disease. Methods the CT data, pathological and clinical features of 7 cases of atypical mesenteric cyst confirmed by pathology were analyzed, including 3 cases of giant mesenteric cyst, 2 cases of mesenteric cyst with hemorrhage, 2 cases of mesenteric cyst with infection. The correlation between CT imaging features, clinical and pathological features was analyzed. Results on CT, there were 3 large cystic lesions in the abdominal cavity, almost occupied the abdominal cavity, the wall of the cyst was thin, the boundary was clear and there was no wall nodule, 4 cases of complex cyst, 2 cases of intracystic hemorrhage and 2 cases of cystic wall thickening with infection. The cysts associated with infection showed a slight increase in the density of the cysts, blurred peripheral boundaries, thickening of the cyst wall, enhancement of the posterior wall of the cyst, and hemorrhage of the cyst accompanied by high density image of the cysts, with no enhancement of the contents of enhanced scanning. 2 cases were correctly diagnosed and 5 cases were misdiagnosed, including 2 cases of ovarian cystadenoma, 1 case of abscess, 1 case of retroperitoneal neurogenic tumor and 1 case of teratoma. The main causes of misdiagnosis were the lack of understanding of the CT manifestations of atypical mesenteric cysts and the neglect of the origin and external causes of the cyst. Conclusion atypical mesenteric cyst has atypical CT manifestations and is easy to be misdiagnosed. The accuracy of qualitative diagnosis of CT could be significantly improved by observing the origin and surrounding organs of the lesion and enhanced scanning.
