Peritoneal lymphomatosis (PL) is an extensive lymphomatous infiltration of the intraperitoneal portion of the subperitoneal space, which is a rare presentation of lymphoma. Using CT or MRI findings alone, it is difficult to differentiate between lymphomatosis, carcinomatosis, and other pathological entities.We experienced two PL cases and herein report the FDG-PET/CT findings. High FDG uptakes were found in omental and peritoneal infiltration, gastric wall involvement, and lymph node involvement in the epiphrenic region, although retroperitoneal lymph node involvement was absent. Systemic abnormal FDG uptakes suggested PL rather than carcinomatosis, and FDG-PET/CT findings were useful for the diagnoses.
腹膜淋巴瘤病（PL）是一种腹膜下腔腹膜内部分的广泛淋巴瘤浸润，是淋巴瘤的一种罕见表现。仅使用 CT 或 MRI 结果，很难将淋巴瘤病、癌性腹膜炎病和其他病理实体区分开来。我们遇到了两个 PL 病例，并在此报告 FDG-PET/CT 结果。在网膜和腹膜浸润、胃壁受累以及膈上区域的淋巴结受累中发现了高 FDG 摄取，尽管没有腹膜后淋巴结受累。全身异常 FDG 摄取提示为 PL 而非癌性腹膜炎病，FDG-PET/CT 结果有助于诊断。
