Synchronous Left Ventricular and Endocranial Mass

Area of Science:

• Cardiology and Neurology
• Diagnostic Imaging
• Infectious Diseases

Background:

• Myocardial cysts are rare, diverse conditions with varied etiologies, including congenital, neoplastic, and infectious origins.
• While often asymptomatic, myocardial cysts can lead to cardiac complications like obstruction, valvular dysfunction, or heart failure.
• The simultaneous occurrence of myocardial and extracardiac cysts, particularly endocranial cysts, is exceptionally rare and can manifest with distinct neurological symptoms.

Observation:

• A 26-year-old male presented with dyspnea and epileptic seizures, indicative of potential cardiac and neurological involvement.
• Echocardiography identified two myocardial cysts within the left ventricle, alongside mitral and tricuspid valve dysfunction.
• Brain computed tomography revealed an additional cystic lesion in the frontal lobe, confirming extracardiac involvement.

Findings:

• The diagnostic workup confirmed the coexistence of myocardial and endocranial cysts.
• Non-invasive imaging modalities, laboratory results, and epidemiological data were instrumental in establishing the diagnosis.
• The patient's presentation underscored the potential for significant cardiac and neurological sequelae from such rare coexisting conditions.

Implications:

• This case emphasizes the importance of a comprehensive diagnostic approach for patients presenting with unexplained cardiac and neurological symptoms.
• Integrated diagnostic strategies combining non-invasive imaging, laboratory tests, and clinical context are vital for managing rare cystic pathologies.
• Accurate diagnosis is essential for guiding appropriate therapeutic interventions and improving patient outcomes in complex cases of coexisting myocardial and endocranial cysts.
