Case report: Echinococcus disease of the bone presenting as a femoral shaft nonunion.

Abstract

Osseous hydatidosis (Echinococcus infection) is a rare parasitic bone infection that poses challenges in diagnosis and treatment. We present a novel case of osseous hydatidosis of the femoral shaft that was diagnosed at the time of surgery for a recalcitrant femoral shaft nonunion. We know of no reports of osseous hydatidosis presenting as a femoral shaft nonunion. A discussion of the challenges in diagnosis and treatment of osseous hydatidosis are discussed, and the literature on osseous hydatidosis is reviewed.
