Case report of a cystic dystrophia appearing in an ectopic pancreas. T
he clinical diagnosis was preoperatively suspected by the findings of
CT scan revealing a tumor located in the wall of the duodenum and by t
he data of MRI indicating its cystic and fibrotic structure. A focus o
f reacting pancreatitis was found in the vicinity of the cystic dystro
phia while the remaining pancreas was normal. The surgical treatment w
as a duodenopancreatectomy, justified by the potential risks of compli
cations.
