A Case of Intussusception Associated with Pneumatosis Cystoides Intestinalis

Pneumatosis cystoides intestinalis (PCI) is an uncommon disease that generally lacks symptoms and is rarely associated with intussusception. A 29-year-old man visited our hospital for right upper abdominal pain. Computed tomography (CT) scan revealed multiple air-filled cysts along the intestinal wall and a pseudokidney sign in the transverse colon. A gastrographin enema examination showed a so-called crab finger appearance and multiple elevated translucency in the transverse colon. From these findings, the diagnosis of intussusception associated with PCI was made. The enema and manipulative reduction improved the intussusception. Comparing the enema findings before and after the reduction, we thought that mobile cecum could play an important role in the intussusception. Colonoscopy was performed after the reduction and showed multiple elevated lesions in the ascending colon, which were similar to cluster of grapes. The CT scan of the next day revealed no recurrence of the intussusception, and the patient has not had symptoms of recurrence ever since.
