Accessory suprarenal gland: report of a case.

The suprarenal glands are normally located at the superomedial aspect of the kidneys. Accessory cortical masses are seen in approximately half of the newborn but usually disappear later. Several cases with accessory cortical tissues located near the main suprarenal glands have been reported but their usual locations have been rarely described. Here we report a case with accessory cortical tissue located on the right in the retrocrural space with compression symptoms. Such a lesion may be confused with lymphadenopathy radiologically.
