Pericardial mesothelioma: the diagnostic dilemma of misleading images

Area of Science:

• Cardiovascular Pathology
• Thoracic Oncology
• Diagnostic Imaging

Background:

• Constrictive pericarditis is a significant cause of heart failure, often diagnosed via imaging.
• Primary mesothelioma of the pericardium is an exceptionally rare malignancy with poor prognosis.

Observation:

• A young male presented with progressive dyspnea, cough, and ascites, initially suspected as idiopathic constrictive pericarditis.
• Surgical exploration revealed an atypical, invasive encapsulating disease, not amenable to complete resection.

Findings:

• Histological examination confirmed primary mesothelioma of the pericardium.
• The patient experienced only partial relief of constriction and succumbed shortly after the procedure.

Implications:

• This case underscores the diagnostic challenges in differentiating primary pericardial mesothelioma from common conditions like constrictive pericarditis.
• Echocardiography and computed tomography (CT) may have limitations in definitively diagnosing invasive pericardial tumors.
• Increased awareness and potentially advanced imaging techniques are crucial for earlier diagnosis of rare pericardial malignancies.
