Extrapulmonary bronchogenic cyst: A case report

Bronchogenic cysts (BCs) are rare congenital lesions that originate from the tracheobronchial bud and can be found in any organ derived from the embryonic foregut. Complete surgical excision is the treatment of choice, and the definitive diagnosis is established by histopathological examination. 41-year-old female with diastolic arterial hypertension and a heterogeneous mass, with multiple calcifications and a solid component with well-defined regular contours. A biochemical study revealed no functionality. Intraoperatively we noticed an adrenal gland-dependent mass with a cystic component and an area of sebaceous content and histological examination confirmed a bronchogenic cyst. The majority of cases of BCs are asymptomatic. They can be intrapulmonary, mediastinal or ectopic, being the left adrenal region the most common retroperitoneal location. Symptomatic cysts should always be surgically resected either by thoracotomy or a minimally invasive technique, which has been shown to improve postoperative discomfort and shorten hospital stay with reliable postoperative outcomes. Despite their low incidence, it is important to consider BCs in the differential diagnosis of retroperitoneal masses, particularly in the left para-adrenal region. •Bronchogenic cysts are rare congenital lesions originating from the tracheobronchial bud.•Surgical excision is the preferred treatment, and histopathological examination for diagnosis.•Are usually asymptomatic, and can be intrapulmonary, mediastinal, or ectopic cysts.•The left para-adrenal region is a common retroperitoneal location for BCs.
