We will discuss the pathophysiology and treatment strategies behind the presented benign and malignant lesions within the humerus. We will demonstrate typical imaging examples and review the imaging characteristics on various modalities.

We present a case-based radiographic review of various benign and malignant lesions which can be found within the humerus. We present the multi-modality imaging characteristics seen on X-ray, CT and MRI, and discuss the pathophysiology behind these lesions.

Enchondroma Enchondroma is a common benign medullary cartilaginous neoplasm. These benign lesions are most frequently incidental findings and diagnosed in childhood to early adulthood with a peak incidence at 10 to 30 years. They account for 3-10% of all bone tumor and 12-24% of benign bone lesions. Enchondromas can occur in any bone formed from cartilage and are typically located centrally within the medullary cavity of tubular bones, such as bones of hands and feet, femur, tibia and humerus. They arise from the chondrocytes in...

The humerus may serve as a common as well as an uncommon location for various osseous lesions. Our case-based multi-modality imaging review of various lesions within the humerusdemonstratestheimaging characteristics, as well as discuss the pathophysiology behind and management strategies for these lesions.
