Summary:

Description
  • Radiopaedia case ID: 63104
  • Image ID: 42482557
  • Image stack position: 22/109
  • Plane projection: Axial
  • Aux modality: bone window
  • Study findings: Large, heterogeneous, relatively low-density mass lesion in the humeral head with foci of calcification, mostly at its periphery. The lesion breaks through the bone circumferentially, involves the glenohumeral joint, and displaces the nearby muscles with loss of the intervening fat plane. Its low density is suggestive of a chondroid matrix. There is a non-enlarged, rounded, axillary lymph node lacking a fatty hilum - cannot be ruled out as metastatic.
  • Modality: CT
  • System: Oncology
  • Findings: Well-defined osteolytic lesion involving the left humeral head and neck. There is a sharp demarcation line from the healthy bone. The lesion erodes the endosteum and invades the joint medially. No periosteal reaction detected. Pathological fracture through the distal third of the lesion.
