Primary adrenal mantle cell lymphoma mimicking a non‐functional retroperitoneal paraganglioma

TL;DR

A case of primary adrenal mantle cell lymphoma was mistaken for a non-functional retroperitoneal paraganglioma based on imaging and symptoms.

Contribution

This case highlights the diagnostic challenge of distinguishing mantle cell lymphoma from paraganglioma using imaging alone.

Findings

A retroperitoneal mass initially suspected as a paraganglioma was diagnosed as mantle cell lymphoma post-surgery.

Histological analysis was crucial for accurate diagnosis, as imaging could not differentiate the two conditions.

Abstract

Patients presenting with abdominal pain and retroperitoneal mass in radiographic images may be in the early stages of primary adrenal mantle cell lymphoma, which requires histological studies for a definite diagnosis.

This report presents a 37‐year‐old woman complaining of ambiguous abdominal pain, with imaging findings revealing a retroperitoneal abdominal mass on the left side of the aorta, and a possible diagnosis of non‐functional retroperitoneal paraganglioma. Total laparoscopic excision was performed. Surprisingly, histological examinations revealed features in favor of mantle cell lymphoma.
