title: [Tumor-like lesions of bone].
abstract: Historically, tumor-like lesions of bone were defined as non-neoplastic bone lesions. Today, however, some of them are considered real neoplasms. They are among the most frequent bone lesions. They usually grow slowly, but occasionally they grow rapidly. Many of them can be diagnosed by plain films alone; in others, CT and MRI yield additional features for a correct diagnosis. Some lesions do not need treatment; others should be resected, and some may even recur. Non-ossifying fibroma, juvenile and aneurysmal bone cysts, fibrous and osteofibrous dysplasia and eosinophilic granuloma are presented.
