A nine-year-old, mixed-breed dog which had been lame for 20 days was found to have a bone tubercle from the centriciput to the occiput by manipulaton and radiography. On the seventh day of its medical treatment, the dog had a sudden convulsive seizure. Cranial computed tomography revealed the presence of severe bone destruction on the occipital and temporal bones and considerable compression of the brain by a mass. CT images of the mass showed high absorption in the occipital lobe and remarkable midline shift. The dog was diagnosed as suffering from intracranial hypertension. An emergency craniotrypesis was performed, and part of the skull bones and the mass were removed. After the surgery clinical manifestations improved dramatically with normalization of the intracranial pressure. But the dog relapsed, and died on day 57. The mass was histopathologically determined to be a multilobular tumor of bone.
