Treatment of symptomatic hepatic cyst by percutaneous instillation of Pantopaque.

A large, symptomatic, simple hepatic cysts was managed by the percutaneous instillation of Pantopaque. The method was based on reports of similar percutaneous treatment of renal cysts. In 6 months the patient was asymptomatic and radiographs demonstrated evidence of a fibrous reaction within the cyst. The patient remains asymptomatic 16 months after puncture. These results suggest that percutaneous instillation of sclerosing agents may provide an alternative to operative procedures.
