[Retroperitoneal bronchogenic cyst mimicking adrenal gland tumor].
OBJECTIVE
To report a case of retroperitoneal bronchogenic cyst, an anomaly during the development of the primitive anterior intestine from which the bronchi and lungs are developed.


RESULTS
A 38-year-old male presented with left lumbar pain. Patient evaluation disclosed a left adrenal polycystic mass which was removed by surgery. Pathological analysis of the surgical specimen demonstrated a bronchogenic cyst. This case is compared with some of the few cases reported in the literature.


CONCLUSIONS
Retroperitoneal bronchogenic cyst is a cause of retroperitoneal tumors in the splenic or hepato-renal region. Although it is uncommon, it should be taken into account when making the differential diagnosis.
