Abstract

The absence of blood flow in the testis on ultrasound examination is the gold standard for diagnosis of testicular torsion. This imaging finding is seen in the vast majority of patients with testicular torsion, except in patients with partial torsion. Patients with partial testicular torsion may have reversal of arterial diastolic flow on spectral Doppler, decreased amplitude of the spectral Doppler waveform (parvus tardus wave), or monophasic waveforms. However, it is important to consider that not all absence of blood flow or reversal of diastolic flow in testis represents testicular torsion, as other conditions may have a similar appearance, including rare detection of such a pattern in normal asymptomatic patients. Conditions that commonly mimic testicular torsion include incarcerated inguinal hernias and complications following hernia repair,thrombotic phenomena, vasculitis, complicated epididymo-orchitis, asymptomatic variants, and technical limitations of ultrasonography. It is important for a practicing radiologist to be familiar with such cases to avoid unnecessary surgical interventions.We present a pictorial essay of cases in which the absence of testicular blood flow on color flow Doppler or abnormal waveforms on spectral Doppler are identified, without the presence of testicular torsion.
