4) Tuberculous epididymitis and tuberculous epididymo-orchitis

These sonographic images of the scrotum of a 65 yr. old male patient known to have filariasis reveal a markedly thickened scrotal wall. The testes itself appears normal. Multiple, hypoechoic tubular channels are seen in the scrotum. These ultrasound images suggest lymphedema of the scrotal wall following filariasis. Images taken using a Toshiba Nemio 30 color doppler machine, courtesy of Dr. Jaydeep Gandhi, Mumbai, India.

2) Testicular abscess:

A case of abscess of the right testes:

This middle aged male patient had a history of drainage of scrotal abscess a few months back. he now presented with discharge, pain and swelling of the right half of the scrotum. Sonography of the scrotum revealed: a) a hypoechoic (almost cystic) lesion with shaggy walls within the right testes with b) another similar lesion extending from the first lesion. c) Color Doppler imaging/ and Power Doppler imaging confirm marked increase in vascularity around both lesions suggesting marked hyperemia and severe right orchitis. These ultrasound images are diagnostic of testicular abscess (right) with extension outside the testes. The left testes also shows evidence of mild orchitis.

Ultrasound images taken by Joe Antony, MD, India, using a Toshiba Nemio - XG Color Doppler machine.

3) Pyocele with orchitis:

This patient presented with swollen scrotum with marked tenderness on the right testes. Ultrasound images show inhomogenous echotexture of the right testes with hypoechoic areas seen in lower part. Color Doppler and Power Doppler images show markedly increased vascularity in the right testes with moderate vascularity in the left testes. There is a large fluid collection around the right testes with multiple fibrous septae within the fluid s/o infected hydrocele (pyocele). These ultrasound and color Doppler images are diagnostic of Bilateral orchitis with pyocele on right side. Ultrasound images by Dr. Joe Antony, MD, India. These images were taken using a Nemio-XG Color Doppler system (Toshiba).

4) Tuberculous epididymitis and tuberculous epididymo-orchitis:

This adult, 48 yr. old male patient had a mildly painful mass in the left scrotum. Ultrasound image shows a hypoechoic, nodular mass of 3 x 2 cms. (appx.) below the left testis, involving the left epididymis (globus minor or tail) and the adjacent part of the left testis. The color and Power Doppler images (right) show considerable vascularity around and within the mass.

Transverse sections (grey scale and color Doppler) images show a small hydrocele around the left testis.The scrotal skin also appears thickened.

The right testis appears normal. Spectral Doppler imaging of the mass shows a low resistance flow within the vessels in this lesion. These color Doppler and ultrasound images show an inflammatory pathology of the left epididymis- typically these findings are those of left tuberculous epididymo-orchitis.

5) Acute epididymitis- case-2:

Power Doppler image- left testis and epididymal head: B-mode image:

Both testes seen: Power Doppler: COlor Doppler image - left testis:

This patient had acute onset of swelling and pain with tenderness over the left scrotum. Ultrasound shows markedly enlarged left epididymis with marked vascularity of the head of epididymis on color Doppler scan. There is also a small left hydrocele with particulate matter within it suggestive of early purulent material within it. The left testis itself is relatively normal in appearance. This suggests a left acute epididymitis involving the epididymal head. The marked enlargement of the epididymal head can mimic a torsion of the left testis; however the presence of normal vascularity in the left testis goes against that diagnosis. This patient will benefit from conservative medical treatment, though surgical intervention may be needed to manage the hydrocele.
