‘No visible lesions?’ an unusual case of Intestinal metaplas
Intestinal metaplasia (IM) of the bladder is an extremely rare benign condition. The clinical features are similar to other bladder tumours. Its pathogenesis is unclear and its role as a precursor of adenocarcinoma has long been debated.

Transurethral resection is the main form of treatment for IM. Published in the Journal of Surgical Case Reports, the authors present the case of a 49-year-old gentleman who presented with visible haematuria. He was submitted to multiple cystoscopies which showed no macroscopic irregularities. Radiological (CT urogram and multiparametric MRI) imaging revealed abnormalities within the bladder neck, suspicious of a neoplastic lesion.

Following transurethral resection of his trigonal area, pathology demonstrated IM occurring on a background of cystitis glandularis. This case highlights the unusual difficulty in macroscopically diagnosing IM of the bladder compared to other neoplasms of the bladder.

Therefore, in patients with persistent visible haematuria there should be a low threshold to perform biopsies.
