Testicular ultrasound (US) studies are nowadays widely performed as being readily available, cost effective with no side effects. Testicular ultrasounds are ordered to help in the diagnosis of various conditions, but more specifically, in cryptorchidism. Other reasons for conducting testicular ultrasonography include testicular pain to confirm presence of epididymitis or orchitis. Consequently, the increase in these studies has raised the rate of finding incidental testicular and extra-testicular lesions. Consequently, knowing the variable imaging features of rare testicular and extra testicular lesions which are crucial, orchiectomy can be avoided. In this article, we present variety of unusual intra-testicular and extra-testicular masses and mass-like lesions with emphasis on key imaging features, main differential diagnosis and recommendation.
