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.
Highlights
Retrocaval ureter, known as circumcaval ureter, is a rare congenital anomaly which usually presents in the 3rd to the 4th decade of life
The commonest presenting complaint is loin pain caused by hydronephrosis due to compression of the right ureter between the inferior vena cava (IVC) and psoas muscle as ureter courses posterior to IVC
Duplication of IVC is a very rare congenital anomaly in the development of IVC which can go totally undetected in the entire life
Summary
Retrocaval ureter, known as circumcaval ureter, is a rare congenital anomaly which usually presents in the 3rd to the 4th decade of life. Retrocaval ureter is commonly seen on right side and rarely on left side if associated with situs inversus or IVC anomalies-left IVC or rarely duplicated IVC. Duplication of IVC is a very rare congenital anomaly in the development of IVC which can go totally undetected in the entire life. Duplication of IVC is most commonly detected on autopsy specimens or may be incidentally diagnosed if associated with other congenital malformations like renal anomalies, retrocaval ureter, venous thromboembolism, and so forth. Duplicated IVC can present with either unilateral or bilateral retrocaval ureter. We are reporting a case of right retrocaval ureter with IVC duplication
