Typical features of intussusception involving the left hemicolon producing coiled spring -like pattern. Note mesenteric vessels to the intussucepted bowel continue to enhance. There is, however, gross proximal large bowel obstruction with marked distension of the caecum. Note markedly thick-walled neurogenic bladder with hydronephrosis.
Rectal gastrografin shows a lobulated mass lesion at the lead point of the intussusception in the sigmoid. The patient had an urgent left hemicolectomy with adenocarcinoma confirmed.
