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。
Objective To investigate the CT manifestations of inflammatory myofibroblastic tumor (IMT) in non-parenchymatous pelvis and its relationship with pathological classification. Methods A retrospective analysis was performed on the features of CT images in 11 cases of abdominocele IMT confirmed by surgery or biopsy. According to the location, size, shape, density and enhancement of tumor, the relationship with the surrounding structure and metastasis And other aspects of the analysis, and pathological results of control, to explore the CT features of abdominal non-solid organ IMT and pathological classification of relevance. Results 11 cases of IMT occurred in 3 cases of mesenteric and retroperitoneal, 2 cases of iliac fossa and bladder, 1 case of omental. CT signs of irregular lobulated or multi-nodular tumor, diameter 2 ~ 18.5 cm; 9 cases of mucinous blood vessels were mixed cystic densities, enhanced solid part was garland-like, nodular significantly delayed enhancement; 1 Cases of spindle-shaped cell-like density for the solid density, with a moderate delay enhancement; 1 case of mucinous vasculature and spindle-cell-dense type exist at the same time, the local lesions were solid, moderately enhanced local lesions were cystic solid , And obviously non-uniform enhancement. Among the 9 cases of mucinous vessels, 4 cases had multiple lesions, 2 cases had adhesions with the surrounding tissues, 1 case had uterus, psoas muscle invasion and lung metastasis. Conclusion The CT findings of non-real abdominal pelvis IMT have certain characteristics, which can reflect the pathological classification.
