# Superior vena cava syndrome associated with sarcoidosis: a very rare case of veinous parietal involvement

## TL;DR

This paper reports a rare case of superior vena cava syndrome caused by sarcoidosis, emphasizing the need to consider inflammatory thickening as a possible cause.

## Contribution

The novelty lies in highlighting granulomatous involvement as a rare cause of superior vena cava syndrome in sarcoidosis.

## Key findings

- SVCS was likely caused by granulomatous inflammation rather than compression or thrombosis.
- The case underscores the importance of considering inflammatory thickening in diagnosing SVCS.
- Appropriate treatment is necessary for such rare presentations of sarcoidosis.

## Abstract

Sarcoidosis, a systemic disorder characterized by non-caseating granulomas, poses diagnostic challenges due to its diverse manifestations. We present a rare case of superior vena cava syndrome (SVCS) secondary to most likely granulomatous involvement in a patient with mediastinal sarcoidosis. While SVCS typically arises from extrinsic compression or thrombosis, our case highlights the importance of considering inflammatory thickening of the SVC wall as a potential cause, requiring appropriate treatment.
