Primary liposarcoma originating from the diaphragm is an extremely rare case. Seventy-four-year-old male presented to emergency department with worsening right upper quadrant abdominal pain with dyspnea. Contrast-enhanced computed tomography of the abdomen demonstrated lobulated mass in right hemidiaphragm exhibiting mass effects to adjacent structures compressing gall bladder. Magnetic resonance imaging of the abdomen showed diaphragmatic mass with heterogeneous signal intensities with partial diffusion restriction. Surgical removal was performed and histology confirmed dedifferentiated liposarcoma arising from the diaphragm with gall bladder invasion.
起源于膈肌的原发性脂肪肉瘤是极为罕见的病例。一名74岁男性因右上腹腹痛加重并伴有呼吸困难就诊于急诊科。腹部增强计算机断层扫描显示右半膈肌有分叶状肿块，对相邻结构有占位效应，压迫胆囊。腹部磁共振成像显示膈肌肿块信号强度不均匀，有部分扩散受限。进行了手术切除，组织学证实为起源于膈肌并侵犯胆囊的去分化脂肪肉瘤。
