"Zoe," a 3 year old female spayed domestic shorthair feline was presented to Red Bank Veterinary Hospital on August 29th, 2007 after having been missing for three days. Clinical signs included sneezing, an acute behavioral change, circling towards the left, right sided proprioceptive deficits, absent right menace response, right sided nasal hypalgesia, in addition to aspects of a right sided hemineglect syndrome. Zoe's lesion was localized to the left proencephalon. Based on Zoe's lifestyle as an indoor/outdoor cat, her history of upper respiratory tract disease, the acute onset of unilateral prosencephalic signs during late August, and the classic MRI findings, a presumptive diagnosis of meningioencephalitis secondary to intracranial Cuterebra migration was made. This paper will discuss the parasite, pathogenesis of disease, related disease, methods of diagnosis, and the treatment protocol.
