Nasomaxillary fibrosarcoma was diagnosed in 3 young horses. Clinical signs included epiphora, facial swelling, dyspnea, unilateral serosanguineous nasal discharge, or an external mass. Physical examination, radiography, and cytology were important diagnostic adjuncts. The definitive diagnosis in each case was based on biopsy. In one case, surgical removal of the tumor and extensive curettage of the affected sinus resulted in extended remission from neoplastic disease.  相似文献   

Urethral recess in two male llamas   总被引：1，自引：0，他引：1  

K I Timm  B J Watrous 《Journal of the American Veterinary Medical Association》1988,192(7):937-938

Contrast radiography revealed a urethral recess in 2 male llamas, and, in 1, an incidental cyst in the wall of the pelvic urethra. The urethral recess was similar to that found in cattle, sheep, goats, and camels. The presence of a urethral recess in llamas makes catheterization of the urinary bladder as difficult in this species as it is in the other species with urethral recesses.  相似文献   

Cystic calculi in two horses

The use of real-time ultrasound for examination of the bladder was a useful diagnostic aid in 2 cases of cystic calculi. The ultrasound procedure revealed that a firm mass palpated per rectum in the bladder of one horse was a calculus. In the other horse, ultrasound revealed additional small uroliths. To remove the uroliths in both horses, laparocystidotomy via a ventral paramedian approach was chosen because it provided the best access to the bladder lumen. The calculi were analyzed by qualitative chemical analysis and quantitative crystallography. Results differed between analysis methods. Crystallography revealed that the mineral composition of both calculi was pure calcium carbonate. Chemical analysis erroneously indicated that the calculi contained phosphate, magnesium, and oxalate.  相似文献
