Sir,

We present ultrasonographic (USG) and Doppler findings of the paraumbilical vein causing medusa head appearance in a case of portal hypertension. A 40-year-old man, a suspected case of liver cirrhosis, presented with complaints of fatigue and abdominal pain. On examination, he was found to have abdominal wall varices around the umbilicus. On USG and Doppler abdomen, he showed features of portal hypertension in the form of hepatopedal flow in the portal and splenic vein and multiple portosystemic collaterals. Dilated (6 mm diameter) paraumbilical vein collateral was seen in the left lobe of the liver, with hepatofugal flow extending to the umbilical region being noted [Figure 1].{Figure 1}

The paraumbilical vein arises from the left portal vein between the lateral and medial segments of the left hepatic lobe and courses along the anterior edge of the falciform ligament. On cross-sectional imaging, paraumbilical collateral number and course vary and they appear as tubular structures more than 2–3 mm in diameter and usually anastomose with the superior epigastric or internal thoracic veins or inferior epigastric vein and drain into superior vena cava or inferior vena cava, respectively.[1] Occasionally, the paraumbilical vein drains into the abdominal veins, creating a “medusa's head” appearance. The paraumbilical system is a frequent abdominal portosystemic pathway, with reported prevalence of 30%–35%.[2],[3] Addition of Doppler imaging to conventional sonography significantly increases the sensitivity for diagnosis of portal hypertension by the demonstration of a paraumbilical vein.[4] A significantly enlarged paraumbilical vein on duplex Doppler ultrasound in cirrhotics may have important hemodynamic consequences, besides predisposing patients to portosystemic encephalopathy; it may also offer some protection against the formation of large varices [Figure 2] and [Figure 3].[5],[6],[7],[8],[9],[10],[11],[12],[13]{Figure 2}{Figure 3}
