# A Rare Case of Idiopathic Chylopericardium Causing Cardiac Tamponade

## TL;DR

A rare case of idiopathic chylopericardium leading to cardiac tamponade is presented, highlighting diagnostic and treatment challenges.

## Contribution

This paper contributes a rare clinical case of idiopathic chylopericardium requiring surgical intervention.

## Key findings

- Idiopathic chylopericardium can present with cardiac tamponade and requires early recognition.
- Conservative management may fail, necessitating surgical intervention for persistent chyle drainage.

## Abstract

Chylopericardium (CP) is a rare clinical entity characterized by the accumulation of chylous fluid within the pericardial space. It can be classified as primary (idiopathic) or secondary, with the latter associated with trauma, cardiothoracic surgery, malignancies, or infections. We present a case of a 67-year-old male patient with idiopathic CP who presented with signs of cardiac tamponade. The patient was initially managed conservatively with pericardiocentesis, dietary modifications, and octreotide but required surgical intervention due to persistent chyle drainage. This case highlights the diagnostic and therapeutic challenges associated with idiopathic CP and emphasizes the importance of early recognition and appropriate management.
