Peritoneal lymphomatosis, defined as the disseminated intraperitoneal lymphomatous infiltration, is a rare presentation usually of non-Hodgkin lymphoma and is associated with aggressive histological subtypes of the malignancy. Recently, the term "peritoneal super scan" has been introduced in positron emission tomography/computed tomography (PET/CT) in a patient with Burkitt lymphoma to describe hypermetabolic lymphomatous involvement of the entire peritoneum, leading to suppression of tracer uptake in organs with otherwise normally increased fluorine-18-fluorodeoxyglucose (F-FDG) uptake. Herein, we report on a patient with Burkitt lymphoma, initially presenting with a peritoneal super scan in PET/CT demonstrating complete metabolic response to R-CHOP (rituximab, cyclophosphamide, adriamycin, vincristine, and prednisolone) therapy.
腹膜淋巴瘤病定义为弥漫性腹腔内淋巴瘤浸润，是一种罕见的表现，通常为非霍奇金淋巴瘤，并与恶性肿瘤侵袭性组织学亚型相关。最近，在正电子发射断层扫描/计算机断层扫描（PET/CT）中，术语“腹膜超级扫描”被引入患有伯基特淋巴瘤的患者，以描述整个腹膜的高代谢性淋巴瘤浸润，导致在其他氟-18-氟脱氧葡萄糖（F-FDG）摄取正常增加的器官中示踪剂摄取受到抑制。在此，我们报告了一名患有伯基特淋巴瘤的患者，最初在 PET/CT 中表现为腹膜超级扫描，显示对 R-CHOP（利妥昔单抗、环磷酰胺、阿霉素、长春新碱和泼尼松龙）治疗的完全代谢反应。
