[Tumor-like lesions of bone].

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.

[MRI morphology of bone tumors and tumor-like lesions].

Spin-echo sequences are mandatory at MRI for staging and characterization of bone tumors and tumor-like lesions. MRI is of minor value in the estimation of the malignant potential of an osseous lesion. Although many bone tumors and tumor-like lesions present similar morphology at MRI, some entities can be diagnosed with good reliability.

[Basic diagnostics of bone tumors].

Primary bone tumors and tumorlike lesions are rare. However, they are found on x-ray incidentally or during examination of a painful skeletal region. This article explains how to diagnose such a detected lesion.
