Congenital unilateral pericardial agenesis presenting as an isolated chest pain in an adolescent: a case report and comprehensive review.

Introduction: Congenital pericardial agenesis is a rare congenital anomaly resulting from the incomplete development of the pleuropericardial membranes during embryogenesis, leading to the partial or complete absence of the pericardial sac. Although this condition usually remains asymptomatic, it can present with various misleading symptoms such as chest pain (add some other, maybe 2, more prevalent presenting symptoms), making diagnosis challenging. Advanced imaging techniques are crucial for accurate diagnosis and management, especially when usual diagnostic modalities do not achieve a definite diagnosis.
