Resumo
A 5-month-old male Rottweiler dog presented with an acute upper motor neuron tetraparesis. A computed tomography study of the cervical spine revealed amorphous mineralization of the soft tissues dorsal to the articular surface of the occipital bone and atlas. The calcification extended into the vertebral canal, causing significant dorsal compression of the spinal cord. Suboccipital craniectomy and partial dorsal atlas laminectomy were performed to remove the extradural calcification. Histopathology was compatible with tumoral calcinosis. Significant clinical improvement was noted in the immediate postoperative period, and there was complete recovery with no recurrence at the last clinical follow-up 15 months postoperatively. Suboccipital craniectomy and partial dorsal atlas laminectomy allowed successful surgical resection of a dorsal craniooccipital tumoral calcinosis in this dog. The decompression resulted in resolution of clinical signs and recurrence is unlikely since there is no underlying disease.
