Long segment intussusception noted at the proximal jejunum causing subacute obstruction with subsequent proximal grosssly dilated jejunum which appears redundant (reaching up to the pelvis). This stretches the duodeno-jejunal junction along the midline (suggestive of mesenteric laxity) . These findings are compatible with jejunojenunal type of enteroenteric intussusception.
The intussuscepiens shows a segment of mildly thickwalled slightly enhancing intussusceptum of invaginated proximal jejunum with mesenteric fat, vessels and insignificant small lymph nodes. The intussusceptum does not show any obvious mass lesion or lead-point.
The duodenum appears normal . Stomach appears dilated. The adjacent vasculature maintains its normal anatomical axis. No obvious volvulus noted.
