Enteroenteric intussusception resulting in small bowel obstruction

Case contributed by Michael P. Hartung
Diagnosis almost certain

Presentation

Abdominal pain, nausea.

Patient Data

Age: 10 years
Gender: Male

Diffuse dilation of the small bowel, leading into a long-segment entero-enteric intussusception with some wall thickening of the intussuscipiens. No clear pathologic lesion to account for the lead point. No adenopathy. The distal small bowel is decompressed. 

Case Discussion

Example of small bowel obstruction in a pediatric patient caused by enteroenteric intussusception. Unfortunately, the final cause is not known in this case due to limited follow-up, but the imaging is instructive and shows the pathology well - particularly on coronal images. The differential diagnosis includes viral illness, benign or malignant mass, and TB (endemic area).
