A case of isolated primary chylopericardium
Insights
A rare case of primary chylopericardium mimicked cardiomegaly in an asymptomatic young man. Diagnosis involved imaging and pericardiocentesis, leading to successful surgical treatment for this pericardial effusion.
Area of Science:
- Cardiology
- Thoracic Surgery
- Diagnostic Imaging
Background:
- Primary chylopericardium is a rare condition characterized by the accumulation of chyle in the pericardial sac.
- It can present insidiously, often mimicking other cardiac conditions.
Observation:
- An asymptomatic 19-year-old man presented with radiographic cardiomegaly.
- Initial investigations including cardiac catheterization and angiography showed fluid collection below the heart.
- Ultrasound confirmed a pericardial effusion.
Findings:
- Thoracic blood pool isotope scanning differentiated the effusion from a cyst.
- Lymphangiography showed contrast in the pericardium, confirming chylopericardium.
- Pericardiocentesis confirmed the diagnosis and provided temporary relief.
Implications:
- This case highlights the importance of considering chylopericardium in the differential diagnosis of cardiomegaly.
- Prompt diagnosis and surgical intervention can lead to favorable outcomes.
- Further research into the etiology and management of primary chylopericardium is warranted.
Abstract:
Primary chylopericardium presented as radiographic cardiomegaly in an asymptomatic 19-year-old man. Normal findings at cardiac catheterisation and angiographic demonstration of cardiac displacement from the diaphragm suggested a collection of fluid below the heart which was confirmed by M and B mode ultrasound scanning. Thoracic blood pool isotope scanning indicated that the lumen was a pericardial effusion rather than a cyst. Lymphangiography did not indicate any direct lymphatic communication though a small pool of contrast appeared in the pericardium and the diagnosis of chylopericardium was confirmed by pericardiocentesis. Surgical treatment was undertaken after rapid reaccumulation of chyle and the patient remains well 6 months later.
