Objective: Bronchogenic cysts are mostly benign,congenital endodermal rests that arise from abnormal budding in the distal tracheobronchial tree. Resulting structures lose the embryological connections with the parent bronchus and may then migrate to different sites. They are located in the mediastinum, neck, lung and rarely heart. Due to the mostly asymptomatic behaviour and the historical confusion regarding histology, an exact prevalence is not known. Case report: We describe here a case of left ventricular wall bronchogenic cyst found incidently on autopsy. Conclusion: Despite the rarity of this pathologic entity, bronchogenic cysts should be considered in the differential diagnosis of cystic lesions of heart. Definitive diagnosis rests on histology. Surgery remains the recommended treatment of choice.
