There were nine cases of male, and seven cases of females.The average age was 52. 8 years. Fourteen cases were studicd by CT, among these cases CT enhancement studies were obtained in five cases. Three cases were studied by MRI. Results: Ten cases were located in upper left part of retroperitoneal space, and three cases in the...

Purpose: To study the CT and MRI findings of retroperitoneal leiomyosarcoma. Materials and Methods: Sixteen cases of retroperitoneal leiomyosarcomas proved by pathology were presented. There were nine cases of male, and seven cases of females.The average age was 52. 8 years. Fourteen cases were studicd by CT, among these cases CT enhancement studies were obtained in five cases. Three cases were studied by MRI. Results: Ten cases were located in upper left part of retroperitoneal space, and three cases in the right wall of pelvic bottom. All cases were single mass, fifteen cases were more than 5 cm in diameter and showed irregular or nodulc in shape. On CT study, all cases were hypodensity (14/14 ), and showed an edge enhancement on contrast injection studies (5/5 ).Most cases were demonstrated a heterogeneous finding on CT or MRI study and found an invasive characteristics. All cases did not find any metastatic lymph nodes. Conclusion: It should be considered the diagnosis of retroperitoneal leiomyosarcoma if a large tumor is found in upper left part of retroperitoneal space or in the right wall of pelvic bottom, and showed obvious invasive characteristics.

目的:研究腹膜后平滑肌肉瘤的CT、MRI表现。材料与方法:本组经病理证实16例,男9例,女7例。平均年龄52.8岁。16例中14例CT检查,其中5例作了强化扫描,3例MRI扫描。结果:肿瘤多见于左上腹膜后(10/16)及右侧盆底壁(3/16)。均为单发,直径>5cm(14/16),多呈不规则结节肿块(15/16)。CT平扫低于肌密度(14/14),强化扫描呈周边强化(5/5),密度不均匀(11/16),多有侵犯特点(15/16),无淋巴结转移。结论:发生于左上腹膜后及右侧盆底有侵犯特点的巨大肿瘤应考虑本病诊断。

Objective To investigate MR signs of the tumors invading the central basicranial area.Materials and Methods MR findings of 65 cases with pathologically proved tumors, including nasopharyngeal carcinoma, juvenile angiofibroma (JA), chordoma, invasive pituitary adenoma, etc. were analyzed, focusing on the signal intensity, location and invasive characteristics of the lesions.Results The signal intensity of some tumors, such as JA and melanoma, carried some characteristics on MRI. The location of the lesion's center was helpful for qualitative diagnosis, as in patients with JA, chordoma, invasive pituitary adenoma and direct invasion from neighboring structures, nevertheless, it would be difficult to make differential diagnosis when the normal structure became extensively involved.Conclusion MRI can well demonstrate the entire extent of the lesion. Based on the signal features, locations and invasive characteristics, qualitative diagnosis can be made for some tumors.

目的 研究中央颅底区域肿瘤的MRI表现 ,探讨其诊断与鉴别诊断要点。材料与方法 分析 6 5例经病理证实的肿瘤(如鼻咽癌、血管纤维瘤、脊索瘤、侵袭性垂体瘤等 )的MRI表现 ,重点观察病变的信号、部位和侵犯特征。结果 血管纤维瘤、黑色素瘤等少数肿瘤的MR信号具有特征性 ,肿瘤的中心部位 (如血管纤维瘤、脊索瘤、垂体瘤及邻近肿瘤的侵犯 )对定性诊断有所帮助 ,当病变破坏广泛时鉴别比较困难。结论 MRI可充分显示肿瘤的范围。部分肿瘤可依据其信号、部位与侵犯特征给予定性诊断

Objective:To study the CT and MRI findings of the retroperitoneal schwannoma,and differ the benign to malignant tumor.Methods:Thirteen cases of retroperitoneal schwnnoma proved by pathology were presented.There were ten male and three female,with an average age of 45.0 years old.Among those cases,four cases were benign tumors,and nine cases were malignant tumors.CT studies were obtained in eleven cases in which CT enhancement studies were done in four cases,MR studies in four cases.Results:Tumors were located in the lateral retroperitoneal space or in the lateral pelvic space.Heterogeneous density or signal intensity was presented in 12/13 cases.Cystis changes were showed in 9/13 cases.There was no any lymphatic adenopathy.For the benign lesion,small with well-demarcated round shape were demonstrated.But in malignant tumor,a big mass with irregular or nodular shape was found.Calcification was seen in 3/9 cases.Irregular enhancement was presented in 4/4 cases.Invasive characteristics were showed in 7/9 cases.Metastasis were in 4/13 cases.Conclusion:If a tumor occurs in the lateral retroperitoneal space,with cystic change,the diagnosis of retroperitoneal schwnnoma should be considered.CT and MRI can differ benign to malignant tumor.
