The cardiovascular structures are normal in size. No abnormalities are noted in the pulmonary parenchyma, mediastinum, or pleural space. There is lysis of the spinous process of the second thoracic vertebra. Spine technique radiographs were requested, confirming the finding from the thoracic series. A pathologic fracture is visible on the additional images.
Aggressive lesion of the T2 spinous process with pathologic fracture. Differential diagnoses include a primary bone tumor, round cell neoplasia, soft tissue neoplasia invading bone, or metastatic neoplasia. This is likely related to the clinical signs of myelopathy.
Hemangiosarcoma.
A large, markedly enhancing mass originated from the T2 spinous process and caused severe spinal cord compression.
