CT manifestations of ileal dysgenesis

Imaging congenital anomalies of the ileum in adults:a pictorial review

The ileal loops are anatomical location for the majority of congenital anomalies affecting the gastrointestinal tract. These include Meckel's diverticulum, ileal duplication, dysgenesis, atresia, mucosal diaphragm, and malposition of the ileum. Symptomatic lesions that often present with abdominal pain, intestinal obstruction or bleeding are usually diagnosed and treated during infancy and childhood. However, many of these congenital conditions may remain clinically silent and detected incidentally in adults undergoing radiological evaluation for unrelated medical reasons. This article presents the spectrum of the congenital ileal anomalies and their distinct features on small bowel examination and CT of the abdomen.

Ileal dysgenesis coexisting with multiple enteric duplication cysts in a child--MR enterography, CT, and Meckel scan appearances

There are numerous causes of iron deficiency anemia due to gastrointestinal tract bleeding in children. While a very thorough history may elucidate common etiologies, such as cow's milk protein-induced colitis and nonsteroidal anti-inflammatory drug-related gastritis or peptic ulcer disease, other less frequent causes often present a diagnostic challenge. We present the MR enterography (MRE), CT and Meckel scan findings of ileal dysgenesis coexisting with multiple enteric duplication cysts in a young child who presented with chronic iron deficiency anemia, recurrent gastrointestinal tract bleeding and unexplained bowel perforation. In this case, MRE was able to identify and characterize each individual lesion and directly guide appropriate surgical management.

Segmental ileal obstruction in neonates--a rare entity

Congenital segmental dilatation of a portion of the small intestine in neonates causing intestinal obstruction is quite uncommon. We hereby report 2 such cases. In both infants, there was localized dilatation of the ileum with collapse of the distal bowel and functional intestinal obstruction without loss of continuity of the bowel wall or lack of ganglion cells.
