From Chronic Irritation to a Rare Malignant Subtype: ¹⁸ F-FDG PET/ CT Imaging of Bladder Squamous Cell Carcinoma following Long-term Suprapubic Catheterisation

Squamous cell carcinoma (SCC) of the urinary bladder is a rare nonurothelial histological variant, accounting for approximately 2%–5% of all bladder cancers. It is generally associated with aggressive clinical behavior and poor prognosis. The major risk factors for bladder SCC include schistosomiasis and chronic urothelial irritation. We present a case of bladder SCC that developed in the setting of a permanent suprapubic catheter maintained for over 10 years.
