ABSTRACT
Intratesticular arteriovenous malformations (AVMs) are extremely rare benign incidental lesions of the testis. Ultrasonography (US) generally reveals a hypoechoic solid mass within the testicular parenchyma. We describe a patient with intratesticular AVM which was found incidentally during workup for infertility. The gray-scale and Doppler US appearance of an intratesticular AVM and the differential diagnosis have been presented. Based on the gray-scale, US appearance differentiation from malignant testicular tumors is difficult. Doppler US examination aids in the diagnosis by demonstrating the vascular nature of the tumor.

fig1: Gray-scale ultrasound image reveals a hypoechoic solid mass within the left testis.

Mentions: A 26-year-old man was admitted to our department for sonographic evaluation of the scrotum due to infertility. On physical examination, both testes were intrascrotal, normal sized, there was no palpable lesion, and no clinical evidence of varicocele. A sperm count revealed an oligospermia (sperm count: 9400000/mL). FSH level was in the upper limit of normal. The α-fetoprotein and human chorionic gonadotropin levels were within normal limits. Gray-scale images showed a well circumscribed, 5.7 mm sized hypoechoic round lesion within the left testis (Figure 1). Color Doppler US demonstrated that the lesion consisted almost entirely of multiple tortuous enlarged vessels (Figure 2). There were 2 dilated vessels on both sides of the vascular mass. One of them was arterial in nature and displayed high flow velocities with a peak systolic velocity of 20.3 cm/s and end diastolic velocity of 13.6 cm/s (Figure 3(a)). The resistive index was 0.33 and pulsatility index was 0.40. The vessel on the other end showed pulsatile venous flow (Figure 3(b)) on spectral Doppler US. Based on the gray-scale and color Doppler US examinations, an arteriovenous malformation of the testis was diagnosed. US findings were not correlated to the patient's fertility status. The patient refused surgery for the mass. Because of the small size of the vascular mass, invasiveness, and risk of radiation, no angiographic imaging and endovascular interventional procedure were performed. During the followup period, there were no changes in patient's clinical and radiological findings.
