TLDR

  • A 72-year-old male patient was diagnosed with aggressive large B-cell lymphoma and presented with rare lymphomatous involvement of the omentum, highlighting the importance of considering this diagnosis in initial staging assessments.

Abstract

Neoplastic infiltration of the omentum is mostly caused by metastatic ovarian, gastric, colon, or pancreatic cancer. Lymphomatous infiltration of the omentum is rare because the omentum lacks a lymphoid component. To date, lymphomatous involvement of the omentum has only been reported in patients with non-Hodgkin lymphoma. Peritoneal lymphomatosis remains a rare presentation of malignant lymphoma characterized by diffuse peritoneal lesions and is frequently accompanied by ascites and mesenteric lesions. In this review, we aimed to illustrate the case of a 72 year old mal patient diagnosed with aggressive large B-cell lymphoma, adressed for initial extension assessment in whomF-fluorodeoxyglucose positron emission tomograph/computed tomography found unusual omental and mesenteric involvement.

Overview

  • The study aims to illustrate the case of a 72-year-old male patient diagnosed with aggressive large B-cell lymphoma, presenting with rare lymphomatous involvement of the omentum.
  • The main focus of the study is to describe the presentation and imaging findings of peritoneal lymphomatosis in a patient with non-Hodgkin lymphoma.
  • The study aims to highlight the importance of considering lymphomatous involvement of the omentum in the initial staging assessment of patients with lymphoma.

Comparative Analysis & Findings

  • The study presents a rare case of lymphomatous involvement of the omentum in a patient with aggressive large B-cell lymphoma.
  • The patient's imaging results, including F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT), showed unusual omental and mesenteric involvement.
  • The findings support the importance of including lymphomatous involvement of the omentum in the initial staging assessment of patients with lymphoma to guide further treatment and management.

Implications and Future Directions

  • The study emphasizes the need for a comprehensive understanding of the presentation and imaging characteristics of peritoneal lymphomatosis to improve diagnosis and treatment outcomes.
  • Future research directions may include investigating the use of advanced imaging modalities, such as FDG-PET/CT, to identify early signs of lymphomatous involvement of the omentum and develop more effective treatment strategies.
  • The study highlights the importance of including lymphomatous involvement of the omentum in the initial staging assessment of patients with lymphoma, which could lead to more effective treatment and improved patient outcomes.
