Findings

There is geographic lysis of the proximal humeral metaphysis with irregularity of the lateral cortex on the craniocaudal projection. There is a more well-circumscribed round radiolucencly proximally which is consistent with the site of previous bone biopsy. The thoracic radiographs are within normal limits.

Differential Diagnosis

Aggressive bone lesion of the right proximal humerus may be due to primary bone neoplasia, fungal osteomyelitis, or metastatic disease.

Diagnosis

  • Metastatic hemangiosarcoma

A splenic mass was found on abdominal ultrasound. Resection of the mass was performed, and hemangiosarcoma was found on histopathology. Right thoracic limb amputation was also performed, and the humeral lesion was found to be metastatic hemangiosarcoma.
