Abstract

Four small breed dogs were admitted with seizures. Magnetic resonance imaging (MRI) of the brain revealed dilation of the olfactory bulb cavity as well as enlargement of the lateral ventricles. These findings demonstrate that dilation of the olfactory bulb cavity can occur concurrent with hydrocephalus. This is the first description of the clinical and MRI features of dilation of the olfactory bulb cavity concurrent with hydrocephalus in dogs.

  Fig. 1 MR images obtained from patients. (A-D) Transverse T1-weighted images (WI) of Case 1, 2, 3, and 4 show the enlarged lateral ventricles, respectively. (E-H) Dorsal T1-WI of Case 1, 2, 3, and 4 show hypointensity lesion (arrows) in olfactory bulb, respectively.
