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.
