Horseshoe adrenal gland associated with type 1 diastematomyelia in an asymptomatic adult

Abstract

A horseshoe adrenal gland is a rare congenital anomaly found almost exclusively in neonates and infants based on autopsy studies. It is a term used to describe a solitary adrenal gland situated in the midline, posterior to the inferior vena cava and abdominal aorta. To date, in the literature, there have been very few cases documented in adults and they have also been reported to be associated with other co-existing intra-abdominal, vascular and vertebral congenital anomalies. We describe a rare case of an asymptomatic adult patient who was incidentally found to have a horseshoe adrenal gland as well as a Type 1 diastematomyelia.
