Primary tumors of the osseous spine

Abstract

Primary tumors of the spine are less frequent than metastatic disease, multiple myeloma, and lymphoma. MR imaging is commonly used to evaluate the spine in patients presenting with pain and can further characterize lesions that may be encountered on other imaging studies, such as radiographs, bone scintigraphy, or CT. This article guides radiologists in identifying these lesions and referring physicians to the appropriate patient evaluation. It also offers directions for avoiding all-encompassing broad differential diagnosis lists in situations where the clinical scenario or specific imaging features can significantly limit the diagnostic possibilities.
