Definitive treatment of congenital liver cyst with alcohol

A full-term newborn boy presented with a palpable liver. Ultrasonography showed a solitary liver cyst. In 6 months the cyst grew 15-fold in volume. Intervention was deemed necessary because of large palpable abdominal mass in spite of the fact that the boy remained asymptomatic. Permanent resolution of the cyst was achieved by percutaneous ethanol injection-aspiration. At 7-year follow-up there has been no recurrence. The authors would like to draw attention to this minimally invasive alternative to surgery.
