Cb. Crocker et Dm. Rings, LYMPHOSARCOMA OF THE FRONTAL-SINUS AND NASAL PASSAGE IN A COW, Journal of the American Veterinary Medical Association, 213(10), 1998, pp. 1472
Lesions of the frontal sinus in cattle may be inapparent radiographica
lly, even when severe enough to cause debilitating neurologic disease.
Lymphosarcoma of the frontal sinus and nasal passage should be consid
ered when clinical and neurologic signs compatible with chronic fronta
l sinusitis are present or when signs are not entirely compatible with
encephalomyelitis.
