Abnormality of hepatic vein (HV) waveforms evaluated by Doppler ultrasonography has been widely studied in patients with chronic liver disease. We investigated the correlation between changes in HV waveforms and portal vein velocity (PVVel), the hepatic artery pulsatility index (HAPI), and also the extent of abnormal Doppler HV waveforms expressed as damping index (DI), severity of portal hypertension expressed as Child-Pugh scores and portal pressure (PP) measured directly from patients with...
Intratesticular epidermoid cyst - here is a well circumscribed intratesticular mass at the upper pole of the right testis. The mass contains alternating hyperechoic and hypoechoic rings, demonstrating a lamellar ("onion skin") appearance. There is no vascularity within the testicular lesion. The surrounding testis is normal. These findings are suggestive of an intratesticular epidermoid cyst - benign testicular tumors which account for 1% of testicular tumors.
