【摘要】：目的探讨腹盆腔非实质脏器炎性肌纤维母细胞瘤(IMT)的CT表现特征及与病理分型的相关性。方法回顾性分析11例经手术或活检病理证实的腹盆腔非实质脏器IMT的CT图像特点,从肿瘤的发生部位、大小、形态、密度及强化特点、与周围结构的关系、有无转移灶等方面进行分析,并与病理结果对照,探讨腹盆腔非实质脏器IMT的CT表现特征及与病理分型的相关性。结果 11例IMT发生于肠系膜及腹膜后各3例,髂窝及膀胱各2例,大网膜1例。CT征象为不规则分叶状或多结节状肿块,直径2~18.5 cm;9例黏液血管型为混杂囊实性密度,增强后实性部分呈花环样、结节状明显延迟强化;1例梭形细胞密集型为实性等密度,呈中度均匀延迟强化;1例黏液血管型和梭形细胞密集型同时存在,局部病灶为实性,中度均匀强化,局部病灶为囊实性,明显不均匀强化;9例黏液血管型中,4例病灶为多发,2例与周围组织黏连,1例伴有子宫、腰大肌侵犯及肺转移。结论腹盆腔非实质脏器IMT的CT表现有一定特征性,可初步反映其病理分型。
[Abstract]:Objective to investigate the CT features of inflammatory myofibroblastoma (IMT) of abdominal and pelvic non-parenchymal organs and its correlation with pathological classification. Methods the CT features of 11 cases of abdominal and pelvic non-parenchymal organ IMT proved by operation or biopsy were retrospectively analyzed. The location, size, morphology, density and enhancement characteristics of the tumor, the relationship between the tumor and the surrounding structure, the presence or absence of metastasis were analyzed, and the results were compared with the pathological results. To investigate the CT features of abdominal and pelvic non-parenchymal organs (IMT) and their correlation with pathological classification. Results 11 cases of IMT occurred in mesentery and retroperitoneum in 3 cases, iliac fossa in 2 cases and bladder in 2 cases. The CT signs of omentum were irregular lobular or multi-nodular mass, and the mucous vascular type of 9 cases had mixed cystic solid density, and the solid part was rosette like after enhancement, and the diameter of the mucous vessel was 18.5 cm ~ (-1). Nodular delayed enhancement was found in 1 case with fusiform cell intensive density, with moderate homogeneous delayed enhancement in 1 case of mucous vascular type and fusiform cell intensive in 1 case, local lesion was solid and moderately homogeneous enhancement. In 9 cases of mucous vascular type, 4 cases were multiple lesions and 1 case was associated with uterus. Conclusion CT findings of non-parenchymal organs of abdomen and pelvis have some characteristics, which may reflect the pathological classification of psoas major muscle.
