Introduction
Osteomas are rare, non-painful, benign bone hyperplasias and occur mainly the in the bones of the head, in pelvis and chest. The aim of the study was to report a case of vertebral osteoma in an adult cat.
Clinical case
A 7.5-year-old, Ragdoll Cross, female Cat, was referred to Companion Animal Clinic with hind limb and tail paresis that progressed through the last 1 year. On admission neurological deficits were compatible with lumbosacral syndrome and motor disorders were more evident in the left hind limb. On Magnetic Resonance Imaging loss of the L6-L7 left nerve root was observed due to bone deposition compatible with spondyloarthropathy.
Results
Nerve root decompression was achieved after L6- L7 lateral hemilaminectomy, corpectomy and foraminotomy. Histological examination was of the bone deposition was compatible with osteoma, thus radiological re-evaluation was suggested in case of recurrence. Post operatively gradual motor recovery was achieved. At the time of writing, 3 months postoperatively, no signs of recurrence are reported.
Conclusions
Surgical bone resection resulted in nerve root decompression and contributed in hind limb and tail motor recovery. Although osteomas are rarely reported in cats, they should be included in cases of vertebral bone decertation.
