Computed tomographic characteristics of frontal sinus ossifying fibroma in a dog.

A 10-year-old female spayed Kelpie cross was presented to The Austin Vet Specialists for further investigation of a mineralized, lobulated frontal sinus mass that had previously been detected radiographically. Computed tomography (CT) revealed a large, expansile, well-defined, heterogeneously mineral attenuating mass invading both frontal sinuses. The mass was surgically debulked via a frontal sinusotomy approach.

Shape of the feline cerebellum and occipital bone related to breed on MRI of 200 cats.

Objectives The MRI features of the feline cerebellum and occipital bone have not previously been described in the literature. The aims of this study were three-fold. Firstly, to document variations in cerebellar shape on MRI in neurologically normal cats to support our hypothesis that crowding of the contents of the caudal fossa or herniation of the cerebellar vermis through the foramen magnum occurs frequently as an anatomical variant.

Rapid vascular uptake of contrast during a retrograde urethro-cystogram in a cat with chronic lower urinary tract disease.

Case Summary: A 9-year male neutered domestic longhair cat was referred to our hospital for investigation of recurrent urinary tract obstruction. The clinical signs had started 12 months earlier and the cat had been catheterised on multiple occasions. Clinical examination and abdominal ultrasound of the abdomen was unremarkable but examination of the penis revealed it to be prolapsed and extremely erythematous and friable.
