“…As there is no accepted screening test for bladder cancer, only a symptomatic presentation triggers a work-up, which classically consists of cross-sectional imaging, cysto-scopic evaluation and histologic examination of tissue sampled during cystoscopy (3). With the increased use of multiparametric magnetic resonance imaging (mpMRI) for prostate cancer there has been recognition that early, incidental bladder cancers can be detected (4)(5)(6)(7)(8). mpMRI of the prostate is now widely used to improve prostate cancer detection, localization and staging (9).…”

mpMRI of the prostate may yield incidental findings, such as small bladder tumors. Awareness of the possibility of incidental bladder lesions is important as 65% of lesions reported in the bladder, not attributable to extension of prostate cancer, proved to be bladder cancer. This may allow for early intervention for asymptomatic patients with undetected bladder cancer prior to disease progression.

“…Recent studies have found incidental findings in the range of 42% [ 7 ]–52.7% [ 8 ]. While the majority of true incidental findings were non-urological, 6.6% of these were considered clinically significant [ 7 ]. Incidental findings were noted to be more common in patients aged over 65, with a ratio of 57% versus 46% in patients aged under 65 [ 8 ].…”

Incidental findings in and around the prostate on prostate MRI: a pictorial review

Prostate MRI has seen rapid growth in use in recent years as an advanced diagnostic modality to detect focal areas of clinically significant prostate cancer, to identify an area for targeted biopsy and to guide management and surveillance. The increase in use has also led to increased diagnosis of incidental lesions arising from structures around the prostate. These incidental findings may be related to the genitourinary system or non- genitourinary system and may have a benign aetiology which needs no additional follow-up, or it may require surveillance and management. The field of view in a multiparametric prostate MRI includes other pelvic organs, neurovascular bundles, bowel, lymph nodes and bones. Being familiar with standard MRI characteristics and a sound knowledge of anatomy of the prostate and surrounding structures can help in distinguishing normal anatomy from pathology. Given that patients undertaking a prostate MRI are usually a cohort with increased anxiety from their known or suspicion of prostate cancer, it is important that radiologists are familiar with these common incidental findings to minimise anxiety to the patient, have a well-informed discussion with the referring clinician and reduce costs associated with unnecessary further testing and follow-up of benign incidental findings. Additionally, being able to diagnose more serious incidental pathologies early can be life-saving and potentially significantly alter patient management.

“…However, it is possible to encounter incidental findings that are not the primary objectives of MRI for the diagnosis of prostate cancer [8][9][10]. If an incidental finding has little clinical significance, it is not a serious concern; however, it could affect the treatment strategy, particularly in bladder cancer cases.…”

Incidental Bladder Cancer Found on Cystoscopy during Prostate Biopsy: Prevalence, Pathological Findings, and Oncological Outcome

et al. 2021

Introduction: We examined the prevalence, pathological findings, and oncological outcomes of incidental bladder cancer found on cystoscopy among patients eligible for prostate biopsy (PB). Methods: We retrospectively reviewed 803 patients who underwent cystoscopy prior to PB between January 2010 and September 2020. In cases of bladder tumor-like findings on cystoscopy, biopsy or transurethral resection of the bladder tumor was performed. The primary and secondary outcomes were the prevalence of incidental bladder cancer and pathological and oncological outcomes of incidental bladder cancer, respectively. Results: Incidental findings were observed in 31/803 patients (3.9%). Bladder tumor-like findings were found in 24/803 patients (3%), while 9/803 patients (1.1%) were pathologically diagnosed with urothelial carcinoma. The stage and grade of incidental bladder cancer were pTa in 8/9 patients and pT1 in 1/9 and low grade in 8/9 and high in 1/9, respectively. The median tumor size of the papillary pedunculated type was 0.5 cm. At 26-month median follow-up, no recurrence was observed. Conclusion: Cystoscopy during PB may yield incidental bladder cancer findings, although the prevalence is very low. Incidental bladder cancer was of low stage and grade, which seemed unrelated to survival. Moreover, performing routine cystoscopy in conjunction with PB is not recommended as it may lead to overdiagnosis of low-risk bladder cancer.
