ABSTRACT

Diagnosis: Enchondroma

History: 67 year old asymptomatic woman presented for screening chest radiograph.

Findings: • Intramedullary "popcorn-like" calcifications in the left humeral shaft on the chest radiograph. NOTE: Metallic "nipple marker" beads • Followup MRI shows a well-defined intramedullary mass within the proximal left humerus diaphysis. T2 hyperintense matrix with predominantly T1 isointense to slightly hypointense signal. • There is diffuse robust enhancement present. Minimal endosteal scalloping is seen. There is no cortical breakthrough or periosteal reaction to suggest an aggressive lesion. Nor is there surrounding soft tissue component.

Ddx: • Enchondroma • Chondrosarcoma • Bone Infarct • Simple bone cyst • Fibrous dysplasia

Dxhow: Characteristic imaging features and absence of symptoms.

Exam: No physical exam findings

No MeSH data available.
