# Cystic Anomaly Manifestation Within the Axillary Fossa: A Case Report of Clinical Significance

## TL;DR

This case report describes a rare ganglion cyst in the axillary region, offering insights into its diagnosis and treatment.

## Contribution

The report adds a new case of a paralabral cyst in the axilla, expanding limited clinical knowledge on this rare condition.

## Key findings

- Paralabral cysts in the axillary fossa are extremely rare, with only eight prior cases documented.
- Accurate diagnosis of axillary masses can be challenging due to the variety of possible pathologies.
- This case highlights the importance of detailed imaging and clinical evaluation for rare shoulder-related cysts.

## Abstract

Ganglion cysts represent a small group of lesions that can arise from almost any joint in the body. Demonstrating a predilection for the joints in the hand and wrist, ganglion cysts in the glenohumeral joint are extremely rare. Due to the vivid array of masses that can be found in the axillary fossa, forming a free-from-error work-up to the correct diagnosis can be quite confounding. In this paper, we present a case of a paralabral cyst of the shoulder joint, located in the axilla. With there being only eight other such cases published in clinical literature, we believe this case report to be of unique importance in gaining further insight into the genesis and treatment of this pathology.
