Abstract

This 17-year-old woman had chronic congenital lymphedema in the left lower extremity since childhood. She underwent surgeries to remove excessive lymphedematous tissues more than 15 times previously. Histopathology of the specimen from the recent surgery revealed angiosarcoma; therefore, FDG-PET/CT scan was arranged to determine the extent of tumor spread, and distant metastases were discovered. Stewart-Treves syndrome is angiosarcomas that arise secondary to chronic lymphedema. Because of the high lethality of this condition, the FDG-PET/CT scan may be a clinically useful imaging modality to detect the possible malignant transformation earlier for patients with chronic lymphedema.

摘要

这位 17 岁的女性自童年起就患有左侧下肢慢性先天性淋巴水肿。她之前已经接受了超过 15 次手术以切除过多的淋巴水肿组织。最近一次手术标本的组织病理学检查显示为血管肉瘤；因此，安排了 FDG-PET/CT 扫描以确定肿瘤扩散的范围，并发现了远处转移。Stewart-Treves 综合征是继发于慢性淋巴水肿的血管肉瘤。由于这种情况的高致死率，FDG-PET/CT 扫描可能是一种临床有用的成像方式，可以更早地发现慢性淋巴水肿患者可能发生的恶性转化。
