Aneurysm of the hepatic artery caused by median arcuate ligament syndrome (MALS).

We present the case of a 74-year-old man, with a history of residual schizophrenia, who underwent abdominal-pelvic CT with intravenous contrast, due to abdominal acute pain, that showed a stenosis at the origin of the celiac trunk and a large aneurysm of the hepatic artery, secondary to a mediam arcuate ligament syndrome, of the diaphragm was observed.

Accumulation of mesalazine pills in the medium ileum in a patient with Crohn´s disease.

Crohn´s disease is an inflammatory disease that can involve any portion of the gastrointestinal tract, although terminal ileum is the most commonly affected portion. It is characterized by a transmural and discontinuous distribution pattern, with alternating periods of active disease and remission. We present the case of a 23-year-old patient diagnosed with Crohn´s disease, in treatment with extended release Mesalazine and corticoids. The CT Enterography showed activity signs and a great dilatation of medium ileum with lots of Mesalazine pills accumulated inside. Pill accumulation occurred because of stenosis, which did not let the pills at this level progress to distal ileum, and be absorbed.
