We present a case of a spontaneous splenoazygos shunt in a patient with liver cirrhosis and portal hypertension, detected by abdominal magnetic resonance imaging. Multiplanar reconstruction demonstrated communication of the splenic vein with the azygos vein that was dilated with a winding course along the mediastinum. This pathway for decompression of the portal vein is an exceedingly rare occurrence.

We present a rare case of pelvic splenosis, and its imaging findings, in a 54-year-old female complaining of pelvic pain and vaginal bleeding for several months. Splenosis is a benign acquired condition defined as heterotopic auto-transplantation of splenic tissue to other compartments of the body and occurs after rupture of the spleen, either traumatic or iatrogenic. Symptoms are unspecific and vary according to the location of the implants; commonly the presenting symptom is abdominal pain or enlarging abdominal mass. Owing to its intrinsic properties and safety, magnetic resonance imaging is a valuable imaging modality, in which the splenosis implants may be securely identified, showing the same signal characteristics and enhancing patterns of the normal spleen, especially visualization of serpiginous enhancement on the arterial phase is virtually diagnostic.
