Herniated Urinary Bladder Detected on 18F-Fluorodeoxyglucose Positron-Emission Tomography/Computed Tomography Scan Imitating as 18F-Fluorodeoxyglucose Avid Lesion.

Inguinal hernia is a common pathology seen in the general population. However, the presence of herniated urinary bladder in the inguinal canal is a rare condition. Most cases are asymptomatic and are detected incidentally either during surgery or on imaging. Here, we present a report, where a patient, diagnosed case of carcinoma esophagus, was referred for staging 18F-fluorodeoxyglucose positron-emission tomography/computed tomography (FDG PET/CT) scan and revealed FDG uptake in the right inguinal canal, other than primary and metastatic lesions and corresponding CT and fused PET/CT images revealed herniated urinary bladder in the inguinal canal.
