Peritoneal lymphomatosis is relatively uncommon cause of diffuse malignant peritoneal disease, and differentiating it from other causes of diffuse peritoneal disease such as peritoneal carcinomatosis is often difficult on imaging. Common findings observed in peritoneal lymphomatosis in contrast to other etiologies include frequent nodal involvement and splenomegaly. We present a case of diffuse peritoneal disease along with ovarian lesions in the absence of abdominal lymphadenopathy or splenomegaly on fluorodeoxyglucose positron emission tomography-computed tomography in the setting of elevated cancer antigen-125 levels, mimicking primary ovarian malignancy causing peritoneal carcinomatosis, which was finally proven to be lymphoma.

Review of Imaging Peritoneal Disease and Treatment.

Article Synopsis
- Peritoneal disease is divided into benign and malignant categories, with malignant cases further classified into primary and secondary types, including conditions like peritoneal mesothelioma and peritoneal carcinomatosis.
- Differentiating between benign and malignant peritoneal conditions is crucial, as this determines the course of treatment and helps avoid unnecessary procedures.
- For patients with secondary malignant diseases like peritoneal carcinomatosis, cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) may offer a chance for cure, and radiologists play a key role in assessing disease extent and potential surgical issues.

Peritoneal lymphomatosis is a rare presentation of lymphoma that can mimic peritoneal tuberculosis. The computed tomography findings in both conditions include omental caking, thickening, and nodularity. We report the case of a 41-year-old man who presented with intermittent abdominal pain and distension.

Article Synopsis
- Peritoneal lymphomatosis (PL) is a rare condition where lymphoma cells spread throughout the peritoneum, often presenting with symptoms like abdominal pain and fever.
- An 82-year-old man underwent various diagnostic tests—PET-CT and exploratory laparoscopy—revealing high-grade B-cell lymphoma after discovering multiple nodules in the abdomen.
- Treatment involved R-CHOP and EPOCH-R chemotherapy, leading to a complete metabolic response; early diagnosis and appropriate chemotherapy are crucial for the management of PL.
