Bronchogenic cysts are rare lesions that form during early embryogenesis and are commonly located in the mediastinum. Retroperitoneal bronchogenic cysts (RBs) are exceptionally rare, with only a handful of cases reported in the modern literature. Here, we report an RB found incidentally on imaging in a patient with suspected nephrolithiasis. We also review the unique imaging and histopathological findings of this entity and discuss why prophylactic surgery is considered the treatment of choice.
