Radiology Cases of Lymphoid Hyperplasia

UGI and SBFT of lymphoid hyperplasia — Spot images from an upper GI small bowel follow through show multiple round filling defects, which represent pseudopolyps, throughout the terminal ileum which is normal in caliber.

Radiology Cases of Lymphoid Hyperplasia Serving as Lead Point For Ileocolic Intussusception

CT and US of target sign and pseudokidney sign in ileocolic intussusception — Axial CT with contrast of the abdomen (above left) shows a mass involving the ascending colon which has a target sign appearance which on sagittal CT (above right) has a pseudokidney appearance. Transverse US of the ascending colon mass (below left) again demonstrates a target sign while the sagittal US of the mass (below right) again demonstrates a pseudokidney sign.

Surgical image of lymphoid hyperplasia — Surgical laparoscopic image shows a thickened edematous terminal ileum containing multiple small bumps within it (to the left of image) representing lymphoid hyperplasia.
