作者在27000次CT 检查中诊断182例脂肪样软组织瘤。其中133例良性,16例脂肪过多症,11例血管肌脂瘤及22例脂肪肉瘤。7例脂肪肉瘤位于腹腔,6例在腹膜后,7例在四肢,颈部及精囊各一例。作者见到,1.良性脂肪瘤诊断无问题,为均匀脂肪密度(-90～-110HU),界限分明,有或无纤维包囊。无浸润。较大者有对邻近组织压迫性影响;2.脂肪过多症亦为-90～-110HU,内部密 The authors diagnosed 182 cases of fatty-like soft tissue tumors in 27,000 CT examinations. Of these, 133 were benign, 16 had hyperlipidemia, 11 had angiomyolipoma and 22 had liposarcoma. Seven cases of liposarcoma were located in the peritoneal cavity, six in the retroperitoneum and seven in the extremities, neck and seminal vesicle. The author saw, 1. The diagnosis of benign lipoma no problem, uniform fat density (-90 ~ -110HU), clear-cut, with or without fibrous cysts. No infiltration. Larger have oppressive effects on the adjacent tissue; 2. Fatty disease is also -90 ~ -110HU, the internal secret
