title: Imaging features of primary tumors of the spine: A pictorial essay.
abstract: Primary tumors of spine are rare accounting for less than 5% of new bone tumors diagnosed every year. These tumors may exhibit characteristic imaging features that can help in early diagnosis and improved prognosis. Plasmacytoma/multiple myeloma and lymphoproliferative tumors are the most common malignant primary spinal tumors. Hemangioma is the most common benign tumor of the spine. Computed tomography is useful to assess tumor matrix and osseous change. Magnetic resonance is useful to study associated soft tissue extension, marrow infiltration, and intraspinal extension. Confusing one tumor with the other based on only imaging findings is not uncommon. However, radiologic manifestations of these tumors need to be correlated with the age, sex, location, and presentation to arrive at a close clinical diagnosis.
