A seven-year-old female neutered domestic short hair (DSH) cat was presented with a three-week history of increased upper respiratory tract noise and dysphagia. Initial investigations included pharyngeal examination under general anaesthesia that demonstrated a left-sided bulging of the pharyngeal wall. A CT study of the head and thorax revealed the extent of a mass arising from the left ventrolateral calvarium. In addition, a contralateral extra-axial intracranial mass and a unilateral thyroid nodule were also evident. No pulmonary metastases were detected. Surgical biopsy confirmed a multilobular tumour of bone (MLTB). Due to the tumour extent and presence of an additional extra-axial lesion, surgery was discouraged. The patient was discharged with palliative analgesia and euthanased three weeks later. The CT findings for MLTB of the feline skull have not been previously reported and are similar to the more common skull manifestation in dogs.

“…The primary vertebral tumors that can invade the spinal canal are osteosarcoma, chondrosarcoma, multiple myeloma, fibrosarcomas and hemangiosarcomas (Mcentee and Dewey, 2013). Besides the vertebral tumors, metastases from breast and prostate carcinomas may also affect the extradural space.…”

“…The patient had a breast tumor removed previously, but no data regarding the histological type. Since mammary carcinoma is the most frequent histological type in bitches with mammary neoplasms, the hypothesis that spinal cord compression was caused by a metastasis of the mammary tumor was entertained, but the histopathological evaluation detected chondroma (Mcentee and Dewey, 2013). The neoplasms of cartilaginous origin located in the spinal cord as chondroma and chondrosarcoma may originate from the vertebral body, via spinous, transverse, pedicle, lamina process or from a metaplasia of the connective tissue adjacent to the spinal cord.…”

This study aimed to describe in detail the surgical technique of partial lateral corpectomy (PLC) associated with pediculectomy to treat an in vitro extradural chondroma. A 12-year old female Cocker Spaniel was seen in the hospital with proprioceptive ataxia of hind limbs associated with extradural compression between the 1st and 2nd lumbar vertebrae. The owner opted for euthanasia since the patient's condition changed due to simultaneous illnesses that culminated in a poor prognosis. The patient's body was formally ceded to perform experimental spinal decompression. The technique was effective to completely remove the epidural mass with minimal manipulation of the spinal cord.

RESUMO.-Foi realizado um estudo retrospectivo de cães atendidos no Serviço de Neurologia (SN) do Hospital Veterinário Universitário (HVU), de 2006 a 2015, com o objetivo de identificar cães com neoplasias encefálicas e obter informações a respeito da raça, do sexo, da idade, dos sinais neurológicos, da localização, da evolução clínica, do tipo e origem do tumor e dos achados de exames complementares e de necropsia. Dos 40 cães com neoplasias encefálicas incluídos neste estudo, 67,5% foram classificadas como de origem primária. Cães sem raça definida e Boxers foram os mais acometidos. Os principais sinais clínicos observados incluíram crise epiléptica, alteração de comportamento e andar em círculo. A região tálamo-cortical foi a mais afetada. Quanto ao tipo do tumor, o meningioma (32,5%) e o oligodendroglioma (12,5%) foram os mais encontrados. A evolução dos sinais clínicos variou entre quatro e 210 dias (média de 44 dias).TERMOS DE INDEXAÇÃO: Neoplasias, encéfalo, doenças de cães, caninos, neurologia, tumores intracranianos, patologia, clínica. INTRODUÇÃONeoplasias intracranianas representam uma causa frequente de disfunção neurológica em animais de companhia de meia idade a idosos (Costa 2009, McEntee & Dewey 2013. O diagnóstico para essa afecção vem aumentando nos últimos tempos com a utilização de técnicas de imagens avançadas, como a tomografia computadorizada e a ressonância magnética. Porém, como ambos os procedimentos não são realizados de forma rotineira em nosso país na maior parte das clínicas e hospitais veterinários, existe a impressão de raridade (Costa 2009). As neoplasias encefálicas primárias incluem os que se originam no parênquima encefálico (células da glia e neurônio), nas células da camada interna e externa do encéfalo (plexo coroide) e em elementos vasculares. As de origem secundária (menos comum, incluem neoplasias metastáticas A retrospective study including dogs with brain neoplasms was conducted at the Service of Neurology (SN) of the Veterinary Teaching Hospital, from 2006 to 2015, with the objective to identify and characterize breed, sex, age, neurological signs, the location, the clinical evolution, the type and origin of the tumor and the findings of complementary examinations and necropsy. Of the 40 dogs with brain tumors included in this study 67.5% were classified as primary origin. Mixed breed dogs and Boxers were the most affected. The main clinical signs observed included seizures, behavioral changes and walk in circle. The thalamus-cortex region was the most affected. Regarding the type of the tumor, the meningioma (32.5%) and oligodendroglioma (12.5%) were the most common. The evolution of the clinical signs varied from four to 210 days (mean 44 days).
