Prevalence, clinical presentation and MRI of intervertebral disc herniations in cats.

Objectives: The aims of this study were to evaluate the prevalence and to describe the clinical and diagnostic imaging features of the different types of feline intervertebral disc herniation (IVDH).

Methods: Medical records and imaging studies were retrospectively reviewed for cats diagnosed with IVDH between January 2008 and October 2020. Information obtained from the clinical records included signalment, clinical presentation, the presence of spinal hyperaesthesia and neurolocalisation.

Malignant Nerve Sheath Tumor of the Hypoglossal Nerve in a Maltese Dog.

A 4 yr old male Maltese dog presented with a 1 wk history of intermittent neck pain and progressive difficulty walking. Neurologic evaluation was consistent with a left-sided brainstem lesion. On oral examination, left lingual hemiatrophy was evident suggesting hypoglossal nerve involvement.

Clinical, MRI, and Histopathological Features of Hypothalamic Neuronal Hamartoma in a Young Vizsla.

Human hypothalamic neuronal hamartomas are rare, nonprogressive, congenital malformations of the hypothalamus that do not expand or metastasize to other locations. A 1 yr old female vizsla was presented for progressive intracranial multifocal neurological signs present since adoption at 3 mo of age. MRI of the brain showed an ill-defined, intra-axial, space-occupying, nonenhancing lesion located in the ventral middle cranial fossa.

Pneumopericardium, pneumomediastinum, pneumothorax and pneumoretroperitoneum complicating pulmonary metastatic carcinoma in a cat.

This report describes a case of severe spontaneous tension pneumopericardium with concurrent pneumomediastinum, pneumothorax and retropneumoperitoneum in a cat presenting with dyspnoea and signs of cardiac tamponade secondary to metastatic pulmonary carcinoma. Spontaneous pneumopericardium is an extremely uncommon condition consisting of pericardial gas in the absence of iatrogenic/traumatic causes. In humans, it has been described secondary to pneumonia or lung abscess and very rarely secondary to pulmonary neoplasia.
