A Rare Case of Right Retrocaval Ureter with Duplication of Infrarenal IVC.

Dudekula A, Prabhu SD - Case Rep Radiol (2014)

Bottom Line: Here, ureter passes between the inferior vena cava (IVC) and psoas muscle and gets compressed.Duplication of IVC is another rare congenital anomaly in the development of IVC.We bring forward this rare type of combination of two congenital malformations.

ABSTRACT
Retrocaval ureter, also known as circumcaval ureter, is a rare congenital anomaly which commonly presents with loin pain in middle age group. Here, ureter passes between the inferior vena cava (IVC) and psoas muscle and gets compressed. Duplication of IVC is another rare congenital anomaly in the development of IVC. We present a case of a 49-year-old male who presented with loin pain and upon thorough investigation was found to have retrocaval ureter along with duplication of the infrarenal IVC. We bring forward this rare type of combination of two congenital malformations.

Mentions: Retrocaval ureter occurs in 1 in 1000 population [3]. Most cases are asymptomatic and are detected only during routine radiologic imaging [4]. There is male to female ratio of 3 : 1 [4]. It occurs more commonly on the right side compared to the left side and is usually associated with other inferior vena cava (IVC) anomalies [5, 6]. Most of the patients with this anomaly usually present with obstructive symptoms because of the compression of the ureter. If the right subcardinal vein in the lumbar portion fails to atrophy and forms the infrarenal IVC, the ureter is trapped dorsally into it and forms retrocaval ureter (Figure 7) [1].
