“…Cães de grande porte à gigante com aproximadamente 20 a 40 kg são os mais acometidos. As lesões nos membros são normalmente dolorosas e causam claudicação dos membros afetados (Hernández-Guerra et al, 2007). O condrossarcoma apresenta maior predisposição para as raças Pastor Alemão, Boxer e Golden Retriever.…”

RESUMO.O condrossarcoma é uma neoplasia óssea com características malignas, que se desenvolve a partir dos tecidos cartilaginosos, classificado na categoria dos sarcomas, está entre os três tumores que mais acometem a região pélvica dos cães. O objetivo deste relato é descrever o caso de um condrossarcoma localizado na articulação sacro-ilíaca direita num paciente canino, fêmea, de 8 anos de idade, da raça Pastor Alemão. Salientando a importância do exame radiográfico na conclusão diagnóstica, ressaltando que o exame histopatológico é o exame de predileção para o diagnóstico definitivo desta afecção. Palavras chave: Neoplasia, pelve, tecidos cartilaginososChondrosarcoma evolution of sacral joint -iliac in a dog: Case report ABSTRACT. Chondrosarcoma is a malignant neoplasm of bone that develops from the cartilaginous tissues, classified in the category of sarcomas, among the three tumors that most affect the pelvic region of dogs. The objective of this report was to describe the case of a chondrosarcoma located in the right sacroiliac joint in an 8-year-old female canine patient of the German shepherd breed. In this way, we emphasize the importance of the radiographic examination in the diagnostic conclusion, emphasizing that the histopathological examination is the examination of predilection for the definitive diagnosis of this affection.

“…The middle cranial fossa syndrome is a well‐recognized syndrome in dogs characterized by variable impairment of these nerves . In the veterinary literature, this syndrome is usually referred to as cavernous sinus syndrome . However, this term should ideally be discarded, because these cranial nerves are not directly related to the cavernous sinus .…”

“…However, this term should ideally be discarded, because these cranial nerves are not directly related to the cavernous sinus . Twelve of 22 dogs published in the veterinary literature showed unilateral deficits, two cases presented with unilateral signs and became bilateral within days, and six cases had bilateral deficits at presentation . All cases were reported to be secondary to neoplasia at the level of the middle cranial fossa or orbital fissure .…”

“…All cases were reported to be secondary to neoplasia at the level of the middle cranial fossa or orbital fissure . Ten dogs were euthanized at presentation, and for the rest, the mean life expectancy after diagnosis was 7.1 months with the longest survival time of 18 months . Clinical signs deteriorated over this period of time in all cases, precipitating euthanasia .…”

“…Ten dogs were euthanized at presentation, and for the rest, the mean life expectancy after diagnosis was 7.1 months with the longest survival time of 18 months . Clinical signs deteriorated over this period of time in all cases, precipitating euthanasia . For this reason, the inclusion criteria of the current study demanded a minimal follow‐up time of 12 months and only dogs with no deterioration of the neurological signs were included.…”

Ophthalmoplegia/ophthalmoparesis (internal, external, or both) has been reported in dogs secondary to neoplasia affecting the oculomotor nerve and is usually given a poor prognosis. The purpose of this retrospective study was to describe the clinical findings, magnetic resonance imaging (MRI) findings, management, outcome, and follow-up in a group of canine cases with idiopathic oculomotor neuropathy. Inclusion criteria included cases with ophthalmoplegia/ophthalmoparesis (internal, external or both) as sole neuroophthalmologic signs, complete ophthalmic and neurologic examination, head MRI, and a minimum follow-up period of 1 year. Dogs with progressive neurological signs not related to oculomotor neuropathy were excluded. Fourteen cases met the inclusion criteria. All cases were unilaterally affected. Magnetic resonance imaging showed equivocal enlargement of the oculomotor nerve in three cases, mild enlargement in five, and marked enlargement in six. Contrast enhancement was present in 12 cases, being marked in six. When present, the contrast enhancement was focal in eight cases and diffuse in four. The median follow-up time was 25 months. External ophthalmoparesis improved in seven cases, five cases under no treatment and two under systemic corticosteroid therapy. The clinical signs in the other seven cases remained unchanged. Idiopathic oculomotor neuropathy should be included as a differential diagnosis in dogs presenting with unilateral ophthalmoplegia/ophthalmoparesis (internal, external, or both) with the absence of other neurologic and ophthalmic signs, and with the MRI findings restricted to the oculomotor nerve. Idiopathic oculomotor neuropathy has a good prognosis as the clinical signs do not deteriorate and they can improve without treatment.
