A Rare Case of a Bladder Neck Abscess Masquerading as a Benign Mass

INTRODUCTION: Bladder neck abscesses are rare urologic pathologies with very few cases published in modern literature. This report explores a case of a bladder neck mass incidentally found on computed tomography (CT) imaging in a patient with an iliopsoas abscess. Case Presentation. We present a case of a 60-year-old woman who was recently treated for sepsis secondary to an iliopsoas abscess in July of 2022. A CT scan revealed an indeterminate structure in the posterior inferior left paramedian bladder wall. During a cystoscopy with transurethral resection of the mass, an abscess was uncovered and evacuated. A postoperative Foley catheter was left in place, and the patient recovered without any complications. CONCLUSION: At the time of publication, the patient feels well and denies pain or lower urinary tract symptoms. Although bladder abscesses are exceptionally rare, incidental findings during cystoscopy may warrant further investigation in patients with comorbid abscesses.
