Pelvic congestion syndrome -MRI

 Chronic pelvic pain with associated ovarian vein varicosities is termed pelvic congestion syndrome (PCS) and is an important but under-diagnosed condition.  The underlying aetiology of pelvic varicosities is reflux of blood in the ovarian veins. The primary defect is the absence of functioning valves within the ovarian veins, resulting in retrograde blood flow and eventual venous dilatation.   Some cases of pelvic varicosities have been associated with mechanical compressive causes, such as uterine malposition, causing kinking of the ovarian vein, and the nutcracker syndrome.  Hormonal influences may also affect the development of PCS.
