A 35-year-old Japanese woman had been diagnosed with a wandering spleen
20 years ago. No symptoms such as abdominal pain was observed before the
delivery of her full-term infant. Contrast-enhanced computed tomography
(CE-CT) was conducted post-delivery. The patient’s spleen was located in
the middle of the abdomen (a) . A few months post-delivery, she
began to have frequent left-sided abdominal pain. CE-CT showed that her
spleen had enlarged and moved into the pelvis (b) . The splenic
artery and vein were spirally twisted 1260° (c) . The congestion
of the splenic vein caused splenomegaly and hypersplenism. The abdominal
pains cause was intermittent blood flow disturbance due to splenic
arteriovenous torsion. A laparoscopic splenectomy was performed. No
abdominal pain occurred post-surgery. The weight of the removed spleen
was 350 g. This was a rare case of wandering spleen with splenomegaly
and abdominal pain due to splenic arteriovenous torsion after
childbirth.
