Hepatorenal cutaneous syndrome demonstrated by 99mTc macro aggregated albumin whole-body scintigraphy.
Hepatopulmonary syndrome, also known as hepatorenal syndrome, is a triad of liver disease, impaired oxygenation, and intrapulmonary vascular abnormalities. Forty-seven percent of patients with end-stage liver disease may have hepatopulmonary syndrome, an independent predictor of poor prognosis. Gross dilatation of pulmonary precapillary and capillary vessels, as well as an absolute increase in the number of dilated vessels, is the classic pathological description. We report a young man with cirrhosis demonstrating extrapulmonary shunting of 99mTc-MAA to kidneys with extensive peripheral arteriovenous (cutaneous) vasodilation, which we prefer to name as the "mosaic sign" in the absence of spider nevi or erythema.
