CT findings of intracranial blastomycosis in a dog.

Abstract

Computed tomography (CT) findings in a dog with intracranial blastomycosis were marked periventricular contrast enhancement of the lateral ventricles, the 3rd ventricle, and the mesencephalic aqueduct. The CT appearance correlated with the histopathologic findings, where severe ependymitis was present throughout the ventricular system and there was stenosis of the mesencephalic aqueduct due to an inflammatory infiltrate. CT is therefore recommended as a screening test for intracranial blastomycosis in dogs and also as an imaging modality for follow-up evaluation after treatment. This is particularly true in dogs with systemic or ocular blastomycosis, which appear to be at higher risk of developing CNS involvement.
