Radiological surveillance of incidental small testicular masses is safe for select patient groups due to the high probability of benign disease, although optimal patient selection criteria and a well-defined protocol are lacking. This approach could be considered for patients with incidental, impalpable testicular masses of <= 5 mm in diameter displaying no significant size increase or internal vascularity on US.
Objective: The increasing use of scrotal ultrasonography (US) for non-cancerous indications has led to greater detection of incidental, small testicular masses. Operative intervention is currently the mainstay of treatment for all testicular tumours; however, despite the low malignant potential of small, incidental masses, little is known about conservative management using radiological surveillance. Methods: A systematic review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was conducted and studies meeting the inclusion criteria were reviewed for patient outcomes. Results: A total of 293 patients across six studies underwent radiological surveillance for an incidental small testicular mass. Infertility was the main indication for investigation and all studies used US as the surveillance modality. A total of 37 patients (12.6%) underwent surgical exploration during follow-up, with only 10 (3.4%) found to have malignant disease at histology. Conclusions: Radiological surveillance of incidental small testicular masses is safe when used for select patient groups due to the high probability of benign disease, although optimal patient selection criteria and a well-defined protocol are lacking. This approach could be considered in patients with incidental, impalpable testicular masses of <= 5 mm in diameter displaying no significant size increase or internal vascularity on US and with negative tumour markers, as the probability of malignancy in these patients is low.
