Findings
- Sclerotic cortically-based lesion along the medial aspect of the proximal humeral metadiaphysis measuring 3.4 x 1.3 cm, which appears to demonstrate continuity with the adjacent bone marrow
- No acute fracture or malalignment
Diagnosis
Sessile osteochondroma
Sample Report
No acute fracture or malalignment.
Sclerotic cortically-based lesion along the medial aspect of the proximal humeral metadiaphysis measuring 3.4 x 1.3 cm, which appears to demonstrate continuity with the adjacent bone marrow. This lesion is favored to represent a sessile osteochondroma rather than a parosteal osteosarcoma, though MRI could further assess as clinically indicated.
