TUMORS INVOLVING THE NERVE SHEATHS OF THE FORELIMB IN DOGS

Nerve sheath tumours were diagnosed in 10 dogs over a three-year perio d. The age at presentation ranged from three to 12 years (mean 6.3 yea rs) and the sexes were equally represented. All the dogs were of mediu m to large breeds. The cases were assigned to two distinct clinical gr oups, which corresponded with the location of the neoplasia. One group presented as a chronic progressive, unilateral forelimb lameness; the se dogs had peripherally located tumours. The other group had an acute onset of signs associated with spinal cord compression without previo us forelimb signs. These were associated with tumours at the level of the spinal nerve roots.
