Multiple vertebral metastases from malignant cardiac pheochromocytoma: Case report

Abstract

A 27-year-old male presented with a very rare metastasis to the vertebral body from a cardiac pheochromocytoma manifesting as a pathological fracture of the C-4 vertebral body that occurred while playing golf. The patient was initially treated with hard collar fixation. Gallium scintigraphy demonstrated multiple hot spots in the mediastinum, the frontal bone, the vertebral column, and the rib. Magnetic resonance imaging of the chest delineated a cardiac tumor. The patient underwent biopsies of the cardiac and the frontal bone lesions. The diagnosis was malignant cardiac pheochromocytoma with multiple bone metastases. Initial irradiation of the cardiac and the vertebral lesions was followed by surgical intervention to the cervical spine to prevent aggravation of the kyphotic deformity and spinal cord compression. Preoperative embolization of the feeding arteries was followed by C-4 corpectomy, iliac bone grafting, and anterior titanium plating fixation. The patient was discharged and returned to work. However, 20 months later, he died of a metastatic brain lesion with systemic tumor progression.
