In this educational exhibit covering a variety of gastrointestinal (GI) and genitourinary (GU) pathologies, we present possible overlooked clues to pathologic diagnosis for 20 interesting cases, with intraoperative and pathologic correlates. We aim to provide teaching points from our experience to help others recognize these helpful imaging findings in their everyday practice.

Educational Goals / Teaching Points
Cover key cross-sectional imaging findings that provide insight into the diagnosis of GI and GU conditions. Provide the reader helpful teaching points and clinical pearls to help consider these diagnoses when presented with similar cases. Intended to serve as a useful review for practicing radiologists and senior residents in preparation for examinations, as well as an introduction for more junior learners.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
A variety of GI and GU cases ranging from common but under-recognized, to outright bizarre, with imaging, intraoperative and pathologic correlates is presented. Cases include prostatic neuroendocrine tumor, prostate sarcoma, uterine leiomyosarcoma, pulmonary arterial leiomyomatosis, peritoneal endometriosis, peritoneal tuberculosis, disseminated fibroid morcellation, small bowel intussusception in a patient with polyposis syndrome, autoimmune pancreatitis, intrathoracic splenosis, periportal extramedullary hematopoeisis, hepatic amyloid, eosinophilic liver disease, gallbladder torsion and more.

After viewing the exhibit, the reader will be able to better recognize imaging clues to common and uncommon diagnoses from a variety of interesting GI and GU cases.
