Peritoneal lymphomatosis in a 52-year-old woman, who had been complaining of abdominal distension and nausea for 3 months. Coronal (a) and axial (b–e) CT images in the portal phase show ascites, confluent nodularity of the omental fat with omental cake appearance (white arrows), thickening of the peritoneal folds (red arrowheads), retroperitoneal lymphadenopathies (blue arrows) and two bulky mesenteric masses that produce encasement of the mesenteric vessels and the adjacent small bowel loops (red asterisks). f, g Fusion PET-CT images show significant standard uptake value of the bulky masses (red asterisks) and the omental cake (white arrows). The final diagnosis of follicular non-Hodgkin's lymphoma was made by surgical biopsy of the mesenteric masses, which corresponded to adenopathic conglomerates
