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.
"Although the incidence of hydatid disease has decreased as a result of education and control measures, there are still foci of concern in South America and sporadic cases still occur in the United States, Europe, the Middle East, and Asia . Hydatid cysts may lie dormant in the bone for as long as 40 years and most skeletal hydatid cysts have been detected in adults. "
[Show abstract][Hide abstract] ABSTRACT: Hydatid disease is common in many parts of the world, and causes considerable health and economic loss. This disease may develop in almost any part of the body.
Bone involvement is often asymptomatic, and its diagnosis is primarily based on radiographic findings. A whole body bone scan is able to show the extent and distribution of lesions.
We describe an unusual case of multifocal skeletal hydatosis and also explain the clinical and diagnostic points. We hope to stimulate a high index of suspicion among clinicians to facilitate early diagnosis and to consider this disease as a differential diagnosis in cases of multiple abnormal activity in bone scintigraphy especially among people in endemic areas.

[Show abstract][Hide abstract] ABSTRACT: Echinococcosis (hydatid cyst disease) in humans is a rare parasitic disease that primarily involves the liver and the lungs.
Skeletal manifestation of the disease is seldom and often presents as a clinical and radiological problem. The contamination
of the primary hydatid cyst complicates the treatment which is also difficult because of the invasive nature of bone involvement
and the spillage of fluid with subsequent contamination seeding. We present a case of pathological femoral fracture secondary
to contaminated primary hydatid cyst that has been finally treated with static intramedullary nailing. We highlight the importance
of including the hydatid bone disease in the differential diagnosis of destructive bone lesions, and we suggest the intramedullary
nailing as the final treatment of specific type of pathological fractures.
