| Abstract: | We report an unusual case of intrapancreatic mesenteric venous collateral vessels following partial pancreatic surgical resection resembling pancreatic neoplasm upon greyscale sonographic and unenhanced CT examinations.Cystic lesions of the pancreas can be divided into three broad categories: lesions without an epithelial lining (pseudocyst), lesions with an epithelial lining (mucinous and serous cystadenoma and cystadenocarcinoma) and degenerative or necrotic change within a solid neoplasm (solid pseudopapillary neoplasm and cystic degeneration of ductal adenocarcinoma or neuroendocrine tumour). Here we report an unusual aetiology for a cyst-like pancreatic lesion: intrapancreatic mesenteric venous collateral vessels developing after a previous partial pancreatic resection. Failure to recognise this condition, particularly during image-guided intervention such as biopsy, endoscopic retrograde cholangiopancreatography (ERCP) or during surgery, could result in a disastrous outcome. |
