Horseshoe adrenal gland associated with retro-aortic right diaphragmatic crus and several vascular variants: Report of two cases

Abstract

Horseshoe adrenal gland (HA) refers to congenital fusion of the adrenal glands across the midline - a rare anatomical variant often found in association with other congenital anomalies. Here we report 2 cases of HA associated with retro-aortic course of the right diaphragmatic crus, yet another rare anatomical variant, in a 61 your-old male and a 69-year-old female, who underwent CT examinations for unrelated reasons. Both patients also had additional vascular and vertebral anomalies. To the best of our knowledge, this is the first report to document association of 2 rare congenital anomalies: HA and retro-aortic right diaphragmatic crus.
