Spectrum of imaging manifestations of tumour recurrences in orthotopic neobladder.

Continent diversion with orthotopic neobladder is the most upcoming form of urinary diversion postradical cystectomy. This allows patients to void through the native urethra preserving the maximal quality of life. These patients with greater life expectancies increasingly present with a wide range of late complications, which also include local recurrences involving neobladder. Such presentations on surveillance scans can be challenging for radiologists unfamiliar with expected post-surgical anatomy and usual sites of local recurrences. Tumour in neobladder, although rare, has predilection concerning specific sites of involvement and few distinct histological types. Major subtypes of such recurrences with corresponding radiological features on multimodality imaging have been discussed in this article. Management of such cases with revision of diversions is challenging, and surgeons expect a meticulous read of such scans before contemplating pelvic clearance and secondary diversions. This pictorial review aims to appraise the literature related to various primary and secondary types of tumours involving reservoir and anastomotic sites in an orthotopic neobladder, their relative incidences and illustrate salient imaging points with case examples.
