The shape, size and density of psoas muscle were analyzed by CT in 499 patients free from symptoms referring to the lumbar spine; 327 males, 172 females. The shape of the muscle is mainly triangular at the levels of lst and 2nd lumbar vertebrae, elliptics dominantly at the levels of L4 and LS. The size of cross—sectional area of the psoas muscle is the largest at level of L4 (13. 56 2. 92cm2). The density of the psoas muscle is 47. 12HU. The older, the less dense.

观察无腰腿痛病史常规CT扫描499人次的腰大肌,其中男327人次,女172人次,对腰大肌的大小,形态,密度等参数观察测量,结果认为腰大肌断面形态在第1、2腰椎平面多为三角形;第3~5腰椎平面多为椭圆形;第4腰椎平面腰大肌断面面积最大(13.56 2.92cm~2),腰大肌的密度不甚均匀,其平均CT值为47.12HU并发现腰大肌断面面积的大小与密度均和年龄成负相关关系。

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 study imaging diagnoses of the broad ligament leiomyoma Methods The findings of ultrasound, computed tomography and magnetic resonance imaging of 9 cases with broad ligament leiomyoma were retrospectively analyzed The diagnosis was proved by operation and pathology Results The findings of ultrasound were pelvic and extrauterine solid hypoechoic masses in all cases There were patchy fluid areas or inhomogeneous hyperechoic points in 4 case, capsule in 5 cases and clear margin in 7 cases Among 8 cases of CT examination, there were solid masses in 7 cases with clear border and homogeneous density similar to uterus muscles and mixed masses in 1 case on plain CT scan The masses were obviously enhanced on contrast enhanced CT scan There were inhomogeneous patchy and non enhanced areas in the tumor in 4 cases MR was obtained in 2 cases, which demonstrated masses with capsule and clear border These tumors had a signal of intermediate or slightly low intensity on T 1 weighted images, while on T 2 weighted images an intermediate signal intensity of the masses with patchy and stripe hyperintense areas were seen The masses were obviously enhanced with patchy non enhanced areas after intravenous Gd DTPA injection Conclusion The detection of a large, solid mass by ultrasound, CT or MR in extrauterine pelvis with capsule indicates broad ligament leiomyoma MR possesses good soft tissue resolution, multi direction imaging and the fat suppression technique which can demonstrate the capsule, inner structure of the tumor, and help establish the diagnoses

目的 研究阔韧带平滑肌瘤的影像诊断。方法 回顾性总结 9例经手术和病理证实为阔韧带平滑肌瘤的B超、CT及MRI表现。结果  9例B超检查表现为盆腔内、子宫外实性肿块 ,呈低回声灶 ,4例内有斑点状液性暗区或不均匀光点 ,5例显示包膜 ,7例边界清晰。 8例CT检查 7例表现为实性肿块 ,边界较清晰 ,平扫密度较均匀 ,与子宫肌密度相当或稍低 ;1例为混合密度灶 ,可见液化、坏死与囊变 ;8例增强扫描实性部分均见明显强化 ,4例可见斑点、片状不强化灶。 2例MRI表现肿块包膜完整 ,与周围脏器分界清晰 ,T1WI为等或略低信号、T2 WI为中等信号 ,内间杂斑点、条状高信号灶 ,注射钆喷替酸葡甲胺 (Gd DTPA)后肿块明显强化 ,其内有斑点状不强化灶 ,包膜显示更清晰、无强化。结论 影像检查 (B超、CT、MR)发现盆腔内、子宫外大而有完整包膜的实性或以实性为主的肿块是阔韧带平滑肌瘤的较具特征的征象 ,对诊断有重要意义。MRI具有良好的软组织分辨率、多方位成像的特点 ,加上脂肪抑制技术 ,有利于显示肿块的成分与包膜 ,对诊断有较大的帮助。最后确诊有赖于手术和病理检查
