Eosinophilic granuloma of the bone: ultrasonographic imaging.

Eosinophilic granuloma is a rare disease of unknown aetiology that affects the bones. Two cases of eosinophilic granuloma are presented. Ultrasonographic, CT and histopathological findings are described. Ultrasonographic-guided core-needle biopsy was performed. Treatment was initiated by installing steroid suspension into the lesions, which resulted in complete healing of the bone in both cases.
