Insights
Sudden cardiac death in a 53-year-old woman was linked to granulomatous myocarditis. This case highlights cardiac sarcoidosis as a potential, underrecognized cause of heart inflammation and sudden death.
Area of Science:
- Cardiology
- Pathology
- Immunology
Background:
- Granulomatous myocarditis is a rare cause of sudden cardiac death.
- Cardiac sarcoidosis, an inflammatory condition affecting the heart, is a key differential diagnosis.
- This is the first reported case of granulomatous myocarditis in Singapore.
Observation:
- A 53-year-old Indian woman experienced sudden death.
- Autopsy revealed bilateral hilar adenopathy, indicative of systemic inflammation.
- Myocardial infiltrates were identified and confirmed to be granulomatous.
Findings:
- The autopsy findings are consistent with granulomatous myocarditis.
- Cardiac sarcoidosis is proposed as the underlying etiology for the observed pathology.
- The case underscores the importance of considering sarcoidosis in unexplained cardiac deaths.
Implications:
- Recognizing cardiac sarcoidosis is crucial for accurate diagnosis and management of heart conditions.
- This case suggests sarcoidosis may be more prevalent in Singapore than previously thought.
- Further research is needed to understand the epidemiology and clinical spectrum of cardiac sarcoidosis.
Introduction:
We report a case of sudden death due to granulomatous myocarditis and propose that cardiac sarcoid could have been the underlying aetiology. This is the first case reported in Singapore. The differential diagnoses for granulomatous myocarditis including sarcoidosis and its cardiac manifestations as well as idiopathic giant cell myocarditis are discussed.
Clinical Picture:
A 53-year-old Indian woman died suddenly and autopsy revealed bilateral hilar adenopathy and myocardial infiltrates which proved to be granulomatous in nature.
Conclusion:
Sarcoidosis may not be a rarity here and it is important to recognise the different clinical manifestations.
