BACKGROUND
Leiomyosarcoma is a malignant neoplasm and can originate within major abdominal veins, including the inferior venacava (IVC).
CASE
A 45-year-old woman presented with upper abdominal pain and a mass lesion in the liver and within the lumen of the IVC. A diagnosis of primary leiomyosarcoma of the IVC was made by using imaging techniques,fine needle aspiration cytology and histopathologic examination of the resected specimen.
CONCLUSION
In patients presenting with vague upper abdominal pain and radiologic features of a hepatic mass extending to major veins, the rare possibility of primary leiomyosarcoma of the IVC shoald he considered and investigated by both fine needle aspiration cytology and intraoperative histology. Early surgical intervention and/or postoperative chemotherapy and radiotherapy are associated with improved survival.
背景
平滑肌肉瘤是一种恶性肿瘤，可起源于主要的腹部静脉，包括下腔静脉（IVC）。
病例
一名45岁女性出现上腹部疼痛，肝脏及IVC管腔内有肿块病变。通过影像学技术、细针穿刺细胞学检查及切除标本的组织病理学检查，诊断为IVC原发性平滑肌肉瘤。
结论
对于出现上腹部隐痛且有肝脏肿块延伸至主要静脉的影像学特征的患者，应考虑IVC原发性平滑肌肉瘤这种罕见可能性，并通过细针穿刺细胞学检查和术中组织学检查进行排查。早期手术干预和/或术后化疗及放疗与生存率提高相关。
