Abstract

A 36-year-old woman with a 2-week history of fever and markedly elevated lactate dehydrogenase levels. Nonenhanced CT and contrast-enhanced CT showed hepatosplenomegaly, diffusely decreased attenuation of the liver, and homogeneous enhancement in the hepatic and splenic parenchyma. F-FDG PET/CT revealed diffuse intense heterogeneous uptake by the liver (like superscan in bone scintigraphy). A liver needle biopsy confirmed the diagnosis of hepatosplenic alphabeta T-cell lymphoma. Subsequently, she received chemotherapy. The follow-up F-FDG PET/CT showed decreased F-FDG uptake in the liver and spleen.

摘要

一位 36 岁女性，发热病史 2 周，乳酸脱氢酶水平显著升高。非增强 CT 和增强 CT 显示肝脾肿大，肝脏弥漫性衰减降低，肝脾实质均匀强化。氟代脱氧葡萄糖正电子发射断层扫描/计算机断层扫描显示肝脏弥漫性不均匀摄取增强（类似于骨扫描中的超级扫描）。肝活检证实为肝脾αβ T 细胞淋巴瘤。随后，她接受了化疗。后续氟代脱氧葡萄糖正电子发射断层扫描/计算机断层扫描显示肝脏和脾脏的氟代脱氧葡萄糖摄取减少。
