Deciphering the Ultrasound, <scp>CT</scp>, and <scp>MRI</scp> Imaging Features of a Post‐Vaginal Hysterectomy Gossypiboma Hiding as a Pelvic Mass—A Case Report

Gossypiboma, or retained surgical sponge, is a rare post-surgical complication with very few reported cases due to medico-legal purposes. Diagnosis is very challenging due to the myriad of clinical presentations and imaging features. We present the case of a gossypiboma detected in a 72-year-old female with a recent history of vaginal hysterectomy. We describe the imaging findings in detail with the step-wise use of X-rays and ultrasound in raising suspicion and computed tomography (CT) and magnetic resonance imaging (MRI) to rule out other differentials and finally come to the diagnosis of gossypiboma, which was confirmed surgically.
