A case of acute relapsing pancreatitis revealing Crohn's disease is re
ported. The diagnosis of chronic pancreatitis was highly suspected bec
ause of characteristic pain, repeated serum pancreatic enzyme elevatio
n and ultrasound, CT-scan, pancreatography, and endosonography data. N
one of the classical aetiologies for chronic or acute pancreatitis wer
e found. This observation presents some outstanding particularities: a
) pancreatitis revealed Crohn's disease; b) there was no duodenal invo
lvement by Crohn's disease, c) the diagnosis of chronic pancreatitis w
as higly suspected, dl corticoids induced dramatic improvement of inte
stinal and pancreatic manifestations, and the patient remained asympto
matic during a two-year follow-up. The efficacy of corticotherapy on p
ancreatic disorders suggests a common mechanism explaining the two dis
eases.
