Description
Summary:Abstract A retrospective institutional-review-board-approved study was performed evaluating positron emission tomography (PET)–computed tomography (CT) imaging findings of peritoneal and omental involvement of lymphoma. Twelve patients were identified with a wide spectrum of imaging findings on PET–CT including but not limited to peritoneal thickening, ascites, and serosal involvement. Lymphoma is among the rare causes of malignant peritoneal or omental involvement. The most common manifestations of peritoneal lymphomatosis are peritoneal 2-[fluorine 18] fluoro-2-deoxy- d -glucose uptake with corresponding peritoneal thickening and nonobstructive serosal masses on CT.
