Low-grade fibromyxoid sarcoma (LGFMS), first described by Evans in 1987, is a rare soft tissue tumor. LGFMS commonly involves the deep soft tissues of the lower extremities, inguinal area, shoulder, axilla, neck and buttock. Intra-abdominal LGFMS has been reported in ten cases in six English studies (small bowel, four cases; mesentery, two; falciform ligament, one; omentum, one; colon, one; diffuse, one), and radiologic imaging studies were done in four of the ten cases. In the present case, radiologic findings of LGFMS showed a well-demarcated multilobular hypoechoic mass on ultrasonography, a multilobular homogeneously enhancing solid mass in the transverse mesocolon on computed tomography and a mildly inhomogeneously enhancing solid mass with two different components on magnetic resonance imaging. We report the first case of LGFMS arising from the transverse mesocolon mimicking lymphoma in a young female patient.
低度纤维黏液样肉瘤（LGFMS）于1987年由埃文斯首次描述，是一种罕见的软组织肿瘤。LGFMS通常累及下肢、腹股沟区、肩部、腋窝、颈部和臀部的深部软组织。英文文献中的六项研究共报道了10例腹腔内LGFMS（小肠4例；肠系膜2例；镰状韧带1例；大网膜1例；结肠1例；弥漫性1例），其中10例中的4例进行了放射影像学检查。在本例中，LGFMS的放射学表现为超声检查显示边界清晰的多叶低回声肿块，计算机断层扫描显示横结肠系膜内多叶均匀强化实性肿块，磁共振成像显示轻度不均匀强化实性肿块，有两种不同成分。我们报告了首例发生于横结肠系膜的LGFMS，该病例为一名年轻女性患者，表现类似淋巴瘤。
