摘要

摘要：男性，37岁，有2个月不明原因发热史，躯干和四肢出现红斑疹。18F-FDG PET/CT显示皮下绒毛炎患者18F-FDG摄取增加，形成雪豹征，伴淋巴结肿大，提示皮下绒毛炎样t细胞淋巴瘤。皮肤活检提示皮下感染，骨髓活检未见异常淋巴细胞。经过抗感染治疗，症状有所改善，最终诊断为全身性感染。本病例表明，PET/CT上广泛的皮下感染可能被误解为皮下泛膜炎样t细胞淋巴瘤。

Subcutaneous Infection With Snow Leopard Sign on 18 F-FDG PET/CT Mimicking Subcutaneous Panniculitis-Like T-Cell Lymphoma.

Abstract: A 37-year-old man presented with a 2-month history of fever of unknown origin and erythema rashes on the trunk and limbs. 18 F-FDG PET/CT revealed increased 18 F-FDG uptake in subcutaneous panniculitis, forming a snow leopard sign, along with enlarged lymph nodes, which suggested subcutaneous panniculitis-like T-cell lymphoma. However, skin biopsy indicated subcutaneous infection, and bone marrow biopsy revealed no abnormal lymphocytes. After anti-infection treatment, symptoms improved, leading to a final diagnosis of systemic infection. This case demonstrates how extensive subcutaneous infections on PET/CT could be misinterpreted as subcutaneous panniculitis-like T-cell lymphoma.
