Rare neural crest tumor in teleost species: olfactory neuroblastoma in a spotted pike-characin Boulengerella maculata.

One spotted pike-characin Boulengerella maculata, managed in a public display aquarium for 7 yr, developed a small unilateral pink growth associated with the right nare. The growth eventually extended through both nares after 5 mo. B.

URINARY BLADDER TRANSITIONAL CELL CARCINOMA AND CARCINOMATOSIS IN A LINNAEUS'S TWO-TOED SLOTH, .

A 19-yr-old female Linnaeus's two-toed sloth () with a history of urinary incontinence, ascites, and behavioral changes was euthanized after diagnostic imaging revealed a large bladder mass. On gross necropsy, the sloth had a severely thickened bladder mucosa, partial urinary obstruction, and nonseptic exudate in the peritoneal cavity. Histopathology showed a malignant and highly invasive transitional cell (urothelial) carcinoma with transmural and intra-abdominal invasion and diffuse carcinomatosis.

Ultrasonographic assessment of long-term enterectomy sites in dogs.

Twenty-eight enterectomy sites from 28 dogs were evaluated sonographically 6 months postoperatively or later. The longest time between the enterectomy and sonography was nearly 7 years. The enterectomy site was visible sonograpically in 22/28 (78.

Ultrasonographic measurement of kidney-to-aorta ratio as a method of estimating renal size in dogs.

Renal size is an important parameter in the assessment of renal disease in dogs. However, because of the great variability in body conformation, absolute renal measurements cannot solely be used when evaluating kidneys with ultrasonography. The use of a ratio comparing renal length and aortic luminal diameter (K/Ao) was investigated.
