Right-sided retroperitoneal bronchogenic cyst: A case report

Introduction: Bronchogenic cysts (BCs) are congenital lesions from abnormal foregut development, usually located in the mediastinum or lungs. While often asymptomatic and benign, they can cause complications. Surgical excision is the definitive treatment.

Case presentation: A 43-year-old female presented with a five-year history of heaviness in the right hypochondrium. Imaging revealed a 15 cm cyst initially thought to be in the hepatic lobe, but a CT scan confirmed it was a retroperitoneal cyst. Laparoscopic excision of the cyst, measuring 11 × 6.4 × 2.3 cm, confirmed it as a bronchogenic cyst.

Discussion: Retroperitoneal bronchogenic cysts are rare, often misdiagnosed due to their asymptomatic nature. This case is the first documented instance of a right-sided retroperitoneal bronchogenic cyst. An integrated diagnostic approach is crucial for accurate diagnosis, given the differential diagnoses involved. Surgical intervention is the gold standard for treatment.

Conclusion: This case emphasizes the rarity of right-sided retroperitoneal bronchogenic cysts and the importance of thorough diagnostic evaluation. Surgical excision is vital for symptom relief and prevention of complications, highlighting the need to consider BCs in differential diagnoses for abdominal masses.
