Günal, ÖmerDoğan, SemihGürleyik, Emin2020-04-302020-04-3020091757-1626https://dx.doi.org/10.4076/1757-1626-2-8420https://hdl.handle.net/20.500.12684/95Fluoro-Deoxy-Glucose Positron Emission Tomography/Computerized Tomography scan is a very useful method in the diagnosis and follow-up of gastrointestinal malignancies, although it may cause confusion in differential diagnosis. We present a 48-year-old man admitted with a right lower quadrant mass. Upon an unyielding colonoscopy due to inability to pass beyond the hepatic flexure, a Fluoro-Deoxy-Glucose Positron Emission Tomography/Computerized Tomography strongly suggested a right colonic or cecal malignancy. Eventual laparatomy revealed a periappendiceal plastron due to appendicitis that was subsequently proven histological diagnosis. Although Fluoro-Deoxy-Glucose Positron Emission Tomography/Computerized Tomography is a reliable diagnostic tool for colonic malignancies, it can misdiagnose such masses due to inflammatory process around the cecum. © 2009 licensee BioMed Central Ltd.en10.4076/1757-1626-2-8420info:eu-repo/semantics/openAccessArticle28N/A
