Fig. 2. Two cases that showed an alternate diagnosis of a pancreatic fluid collection. (A) Cystic structure with internal debris visualized with endoscopic ultrasound (EUS) (arrow). Cytological evaluation was consistent with a cystadenocarcinoma. (B) Cystic lesion with thickened wall and mural nodules visualized by computed tomography (arrow). Was later confirmed by EUS fine needle aspiration cytology to be a neuroendocrine tumor. Image courtesy of Eric Tamm, MD.
