Duodenal diverticulum as a cystis neoplasm of pancreas

Abstract

Objective: The duodenal diverticulum presents with a frequency of 1 to 23% according to radiological series and autopsies. The most frequent localization is the second duodenal portion near the pancreatic head so it may be confused with cystic pancreatic neoplasms.

Material and Method: We present a patient with diagnosis of radiological suspicion by means of echoendoscopy and fine needle aspiration biopsy (FNAB) of a mucinous neoplasm of the pancreas that was intervened, being a hardening of the pancreatic head and a duodenal juxtavaterian diverticulum, being performed a block removal on suspicion of malignancy.

Result: The patient’s postoperative period was favorable and the anatomopathological result of the pancreatic tissue was of pancreatic tissue without anomalies and duodenal diverticulum.

Discussion: The preoperative differential diagnosis of duodenal diverticulum with mucinous cystic neoplasia of the pancreas is very complex, since the puncture of the fluid inside the diverticulum may be similar to that of a neoplastic process of the pancreatic mucin. Before the suspected diagnosis and the presence of clinic is indicated to perform exploratory laparotomy, to obtain a diagnosis of certainty.
