RESUMO

A 12-year-old female African Clawed Frog (Xenopus laevis) displayed lethargy and anorexia for 1 week. Radiographs detected a moderately reduced volume of aerated lung with lobulated margins with the left lung predominantly affected. Transcelomic ultrasound revealed marked consolidation of the left lung. Postmortem examination confirmed suppurative and histiocytic pneumonia, worse in the left lung, caused by Mycobacterium chelonae. Given that amphibian pulmonary consolidation and celomic effusion can have similar radiographic findings, ultrasound may be helpful to differentiate.

RESUMO

A 12-year-old blue-fronted Amazon parrot (Amazona aestiva) of unknown sex (case 1) and a 14-year-old female hybrid Catalina macaw (Ara ararauna × Ara macao) (case 2) were evaluated and treated for an open tarsometatarsal fracture and a tibiotarsal fracture, respectively. In case 1, 1 month of external coaptation resulted in a delayed union, significant osteolysis, and presumptive osteomyelitis, which led to the decision to treat with a key ring fixator. In case 2, a key ring fixator was chosen for fracture repair because of presumed resistance to destruction by the bird. In both cases, fractures were stabilized with makeshift circular external fixators composed of key rings, K-wires, orthopedic wire, and acrylic resin. After key ring fixator removal, radiographs confirmed complete bone healing. Both patients had acceptable function of the affected limbs 5 years (case 1) and 2 years (case 2) after their procedures. The key ring fixator described in this report is a viable option for fracture repair in pelvic limbs of moderately sized birds (300-1500 g).

RESUMO

A 2 year old, spayed female African serval was evaluated for a history of abdominal distention. Physical examination findings were consistent with cranial abdominal masses and anemia. Abdominal imaging revealed soft tissue opacity masses in the cranial abdomen and hypoechoic cysts arising from the liver parenchyma. Conservative management failed to improve clinical signs, and a midline exploratory laparotomy was performed. Three large hemorrhagic cysts were visualized occupying a significant amount of the liver parenchyma. The cysts were drained, omentalized and partially closed with a surgical stapler and suture. Histopatological evaluation of the resected tissue was consistent with a chronic hepatic hematoma. The patient recovered well and was discharged 3 days postoperatively. Two years later, the patient was readmitted with the same clinical signs and large multiple hepatic cysts involving most of the liver lobes. These were surgically omentalized similarly to the previous surgery and the patient recovered well postoperatively. Two years later, return to normal life and no recurrence of the cysts was reported.

RESUMO

To determine risk factors and seasonal trends of lead poisoning in bald (Haliaeetus leucocephalus) and golden (Aquila chrysaetos) eagles, blood lead levels were evaluated in eagles admitted from the inland Pacific Northwest region of the United States to the Raptor Rehabilitation Program, College of Veterinary Medicine at Washington State University from 1991 to 2008. Admissions were from Washington (32 bald eagles, 27 golden eagles), northern Idaho (21 bald eagles, 25 golden eagles), northeastern Oregon (5 bald eagles, 6 golden eagles), Montana (2 bald eagles), Alaska (1 bald eagle), and unrecorded (6 bald eagles, 5 golden eagles). In these birds, 48% (22/46) of bald and 62% (31/50) of golden eagles tested had blood lead levels considered toxic by current standards. Of the bald and golden eagles with toxic lead levels, 91% (20/22) and 58% (18/31) respectively, were admitted after the end of the general deer and elk hunting seasons in December. Coyote hunting intensifies with the end of the large game hunting seasons and coyote carcasses left in the field and contaminated with lead bullet fragments become readily available food sources, exposing scavenging bald and golden eagles to high risk of acute lead poisoning.

RESUMO

CASE DESCRIPTION: A 2-month-old male degu was treated for preputial damage and lateral penile displacement that occurred during attempted castration. CLINICAL FINDINGS: Bruising and swelling of the prepuce and severe edema to the left of the prepuce were evident. The penis could not be extruded from the prepuce. Radiography revealed a large bladder. Contrast medium injected into the prepuce filled the peripreputial subcutaneous tissues. TREATMENT AND OUTCOME: During surgical exploration through a peripreputial approach, the penis was found to be completely separated from the prepuce and located in the adjacent subcutaneous tissue. The penis was repositioned in the prepuce and anchored with a suture at its base. The following day, the preputial orifice was crusted over, urine was leaking from the incision, and the penis could not be extruded from the prepuce. The anchoring suture was removed, and the tip of the penis was sutured to the preputial orifice so that the penis protruded slightly from the prepuce. Urination was normal after the second surgery. Two years later, the preputial orifice remained adhered to the distal portion of the penis and the exposed penile tissue was healthy. CLINICAL RELEVANCE: Penile displacement from the prepuce is an unusual complication of castration in degus. The surgical technique used in this animal may be an effective means of repair. Permanent exposure of the tip of the penis may be well-tolerated in degus.

RESUMO

Three bald eagles (Haliaeetus leucocephalus) found along highways and unable to fly were presented for evaluation. All eagles exhibited sternal recumbency, as well as flaccid hind limb and tail paralysis. Vertebral column and spinal cord trauma were suspected as the cause. One bird died, whereas the remaining 2 birds were stabilized for diagnostic imaging studies. All 3 birds were evaluated by radiography and magnetic resonance imaging (MRI) for diagnosis and for prognosis in the live birds. Radiographic findings in all 3 birds were inconclusive, whereas MRI results showed extensive damage of the spinal cord and vertebral column, precluding functional recovery. The 2 surviving birds were euthanatized. In all birds, MRI assessments correlated well with necropsy and histopathologic findings.

RESUMO

A 5-year-old male castrated ferret was presented to the Washington State University College of Veterinary Medicine for evaluation of progressive hair loss and a large, rapidly growing ventral neck mass. The patient had been diagnosed previously with an insulinoma, which was managed medically. Fine-needle aspirates of the neck mass were performed. The cytologic results were most consistent with epithelial neoplasia, likely a carcinoma; thyroid origin was considered likely based on tumor location and cell morphology. The tumor grew rapidly, and the owners elected euthanasia 1 week after examination. At necropsy, a circumscribed, ovoid mass disrupted the right cervical musculature next to the right lobe of the thyroid gland. Histopathologic evaluation revealed an infiltrative mass consisting of cuboidal cells arranged in solid sheets and irregular follicles enclosing colloid. The cells were large, with prominent nucleoli, and had a high mitotic rate. The histopathologic diagnosis was consistent with thyroid follicular adenocarcinoma. Immunochemical findings confirmed thyroglobulin production by neoplastic cells, but to a lesser extent than in normal ferret thyroid tissue. To our knowledge, this is the first case of thyroid follicular adenocarcinoma to be reported in a ferret, with only 1 other case of thyroid carcinoma, a C-cell carcinoma, described previously.
