Abstract Obstructive or nonobstructive hypertensive hydrocephalus is reported in choroid plexus tumors. Choroid plexus tumors typically present as T2‐weighted hyperintense intraventricular masses with occasional cerebr...

Abstract Background Peripheral nerve sheath tumors (PNSTs) are a group of neoplasms originating from Schwann cells or pluripotent cell of the neural crest. Therapeutic options and prognosis are influenced by their degree...

Abstract Background Cervical spondylomyelopathy (CSM) occurs because of compression of the cervical spinal cord, nerve roots, or both, usually affecting young adult to older large and giant breed dogs. Juvenile dogs are ...

Abstract Background Brain imaging suggests the involvement of the limbic system, particularly the cingulate gyrus (GC), in dogs with idiopathic epilepsy (IE). Hypothesis A correlation exists between the side of intericta...

Abstract Background Magnetic resonance imaging is the method of choice for diagnosing spinal cord neoplasia, but the accuracy of designating the relationship of a neoplasm to the meninges and agreement among observers is...

Abstract Background Intracranial neoplasia is relatively common in dogs and stereotactic radiotherapy, surgical debulking, or both, are the most successful treatment approaches. A key component of treatment planning invo...

Abstract Background There is a successful outcome after surgical management of spinal arachnoid diverticula (SAD) in up to 82% of cases. Hypothesis/Objectives We hypothesized that Pugs have favorable short‐term and poo...

Abstract Background In humans, the T2‐weighted (T2W)—fluid‐attenuated inversion recovery (FLAIR) mismatch sign (T2FMM) is a specific imaging biomarker for the isocitrate dehydrogenase 1 (IDH1)‐mutated, 1p/19q non...

Abstract Background The diagnosis of idiopathic epilepsy (IE) in dogs is based on exclusion of other potential causes of seizures. Recently, a novel magnetic resonance imaging (MRI) sequence that utilizes a variant of th...

Abstract Background Gliomas in dogs remain poorly understood. Objectives To characterize the clinicopathologic findings, diagnostic imaging features and survival of a large sample of dogs with glioma using the Comparativ...

Abstract Background Lesions causing refractory epilepsy, often associated with temporal lobe epilepsy (TLE), can be undetectable on standard magnetic resonance imaging (MRI) in dogs. Automated brain volumetry, widely use...

Abstract Background Brain tumor therapeutic responses can be quantified from magnetic resonance images (MRI) using 1‐ (1D) and 2‐dimensional (2D) linear and volumetric methods, but few studies in dogs compare these t...

Abstract Acquired cervical scoliosis previously has been reported in dogs as a clinical sign associated with Chiari‐like malformation and syringomyelia but has not been described with inflammatory central nervous syste...

Abstract Feline infectious peritonitis (FIP) is caused by a mutant biotype of the feline enteric coronavirus. The resulting FIP virus (FIPV) commonly causes central nervous system (CNS) and ocular pathology in cases of n...

Abstract Background Constrictive myelopathy (CM) involving a fibrous band around the spinal cord is a newly recognized disease in pug dogs. Objectives To identify the frequency of CM based on diagnostic imaging supplemen...
