Primary bone lymphoma : imaging findings of a rare primary bone tumour

Abstract

Primary bone lymphoma (PBL) is a rare cause of primary bone malignancy and it is unusual for extranodal lymphoma to arise in the skeletal system. The imaging appearance is variable and the diagnosis is usually made on histology. We present the radiographic and CT features of primary bone lymphoma of the humerus in a young patient and discuss the variable imaging appearances of this condition.
