Rare Solitary Primary Osseous Lesions of the Spine in Adults, Challenges in CT and MR Imaging Diagnosis With Pathological Correlation

Abstract

This pictorial essay is a review of the computerized tomography and magnetic resonance imaging of a few solitary primary osseous lesions encountered in the adults. The lesions discussed include giant cell tumor, Langerhans cell histiocytosis, Paget'sdisease, plasmacytoma, fibrous dysplasia and osteoblastoma. Challenges in computerized tomography and magnetic resonance imaging diagnosis of these lesions are mentioned with clinicoradiological differential diagnosis, and include pathological correlation. Although active diagnosis and radiological familiarity of these lesions is crucial for preventing unnecessary examinations or procedures, pathological evaluation is mandatory to establish final diagnosis.
