Mural bladder abscess in a 61-year-old man with recurrent UTIs and clinical and sonographic suspicion of bladder carcinoma. Multiplanar CT images (ad) depicted a poorly distensible bladder with mural thickening (*), urothelial hyperenhancement (thin arrows) consistent with active UTI, and a fluid-like collection (arrowheads) with irregular peripheral enhancement along the posterolateral aspect. Urine cytology and cystoscopy excluded the presence of tumour. Six weeks later, repeated CT (d) after antibiotic treatment showed resolved abscess, persistent mural thickening (*) and infectious urothelial enhancement (thin arrow). Further follow-up with MRI including T2- (e) and post-gadolinium T1-weighted (f) sequences confirmed abscess disappearance (arrowheads)
