Testicular infarction mimicking tumour on scrotal ultrasound--a potential pitfall.

We present two cases of spontaneous testicular infarction. Although the clinical presentation indicated an acute pathology, the ultrasound examination demonstrated focal, hyporeflective intra-testicular lesions that could not be discriminated from tumour. As a result of the ultrasound examinations, radical orchidectomies were performed and diagnoses of spontaneous testicular infarction proven histologically.
