Successful Management of Massive Congenital Hepatic Hemangioma and Systemic Hypertension With Sirolimus.

Congenital hepatic hemangioma (CHH) is a common benign vascular tumor of the liver, seen in infancy. The clinical manifestations vary from incidental findings to life-threatening complications. The authors present here a case of an infant with massive CHH who developed systemic hypertension because of compression of the right renal artery by the CHH and did not respond to other lines of treatment. After sirolimus therapy, the CHH size decreased and antihypertensive drugs were no longer necessary. In a critical situation, if the embolization and/or steroids do not seem to control the situation, then adding sirolimus may be considered as secondary therapy with good additive effects.
