# Mimickers of pituitary tumors

## TL;DR

This paper reviews conditions that can mimic pituitary tumors on imaging, helping avoid misdiagnosis and unnecessary treatment.

## Contribution

The paper provides a comprehensive review of non-neoplastic conditions that resemble pituitary tumors.

## Key findings

- Many non-cancerous conditions can mimic pituitary tumors on imaging.
- Distinguishing true tumors from mimics is crucial for appropriate management.
- A structured approach is suggested to guide clinical decision-making.

## Abstract

Enlargement of the pituitary gland and/or its surrounding structures on brain or sellar imaging is a frequent finding. The distinction between clinically relevant and incidental changes can be challenging. Furthermore, the assumption that sellar lesions reflect a true neoplasm must be rigorously questioned to avoid inappropriate treatment or unnecessary surveillance plans. Here we review wide-ranging conditions that can mimic primary pituitary tumors. We outline a suggested approach to rational decision-making.
