A 64-year-old patient presented with shortness of breath and chest pressure. The initial examination was unremarkable, and a chest X-ray revealed a large mediastinal mass. Computed tomography (CT) scan demonstrated a lobulated mediastinal mass involving the great vessels and mass effect on the trachea, esophagus, and heart. A CT-guided biopsy showed a monotonous, evenly spaced population of mature, normal-appearing adipocytes consistent with a well-differentiated lipoma-like liposarcoma/atypical lipomatous tumor. The patient underwent a median sternotomy with tumor resection without adjuvant chemoradiation. Three-year follow-up CT imaging shows no evidence of tumor recurrence.
一名64岁患者出现呼吸急促和胸部压迫感。初步检查无异常,胸部X光显示纵隔有一个大肿块。计算机断层扫描(CT)显示纵隔有一个分叶状肿块,累及大血管,对气管、食管和心脏有占位效应。CT引导下活检显示为一群成熟、外观正常的脂肪细胞,排列单调且间距均匀,符合高分化脂肪瘤样脂肪肉瘤/非典型脂肪瘤性肿瘤。患者接受了正中胸骨切开术并进行肿瘤切除,未进行辅助放化疗。三年随访CT成像显示无肿瘤复发迹象。
