title: Magnetic resonance imaging of the brain for diagnosis of neurocysticercosis in a dog.
abstract: Neurocysticercosis was diagnosed in a 2-year-old spayed Whippet by use of magnetic resonance imaging. The dog was evaluated because of a 3-month history of slowly progressive balance and directional abnormalities, which were indicative of brain stem disease. Magnetic resonance imaging of the brain and CSF analysis were chosen as the best diagnostic modalities for determination of the primary disease. Results of CSF analysis were within reference ranges. Examination of T1-weighted, contrast-enhanced, 3-mm-thick axial, sagittal, and coronal views of the brain revealed multiple cyst-like lesions. The cysts had high-signal-intensity, ring-like peripheral margins and were located in the subdural portion of the left occipital lobe and the dorsal midline and right dorsolateral aspect of the brain stem. A tentative diagnosis of neurocysticercosis was made on the basis of similar findings in human beings with this disease. Treatment with albendazole and prednisone was initiated, and clinical signs resolved during the following weeks. Repeat magnetic resonance imaging confirmed resolution of the disease.
