The natural history of mesenchymal hamartoma of the liver is poorly un
derstood. This case demonstrates the course of a biopsy-proven mesench
ymal hamartoma using sequential computed tomography (CT) examinations.
These CT scans show initial expansion of the lesion with subsequent i
nvolution, The spontaneous resolution in this patient suggests the pos
sibility of conservative management of asymptomatic mesenchymal hamart
omas. The case is presented, and the literature on mesenchymal hamarto
ma is reviewed. Copyright (C) 1997 by W.B. Saunders Company.
