Magnetic resonance imaging (MRI) was also done which confirmed the diagnosis of post-partum ovarian thrombosis (POVT), (Fig.
An abdominal Ultrasound performed showed mild right hydronephrosis and right hydroureter with thrombosis of the right ovarian vein extending into the inferior vena cava (POVT), (Fig.
Puerperal endometritis has been postulated as a possible cause of POVT. Anaerobic bacteria, which are usually present in the lower genital tract, are able to generate endothelial injury and stasis with secondary thrombosis of the pelvic veins.
The usual clinical features of POVT are as described in the cases above.
A positive diagnosis of POVT can be made by Ultrasonography, Magnetic resonance imaging (MRI) or MDCT scan with a sensitivity of 52%, 92% and 100%, respectively.
