A 2-year-old spayed female English Setter that arrived in Atlanta on a flight from South Africa was boarded at a nearby quarantine facility. The day following its arrival, the dog appeared to be dead and was brought to the referring veterinarian. The dog's rectal temperature was 41.7°C (107°F) at that time, and cardiopulmonary resuscitation efforts were unsuccessful. No other external abnormalities were noted, and the body was submitted to the Athens Veterinary Diagnostic Laboratory at the University of Georgia for necropsy.
Clinical and Gross Findings
At necropsy, the dog weighed 14.5 kg (31.9 lb) with a body condition score
A 7-year-old 15.9-kg (34.9-lb) spayed female Welsh Pembroke Corgi was evaluated because of respiratory difficulty of approximately 1 month's duration. On examination, the dog was tachycardic and tachypneic with harsh lung sounds and crackles that were loudest in the right ventral lung field. A CBC revealed regenerative anemia; hypercoagulability was suspected because multiple blood samples clotted immediately after they were collected and before a coagulation profile could be performed. Thoracic radiography revealed a mass of soft tissue density in the right caudal lung field that displaced the heart to the left and the remaining right lung
A client-owned 12-year-old 10.3-kg (22.7-lb) female shusui koi (Cyprinus carpio) was evaluated because of an ulcerated mass on the left body wall, hyporexia, and decreased activity.
The patient was anesthetized with a solution of eugenol in water for all examinations and procedures. An approximately 7 × 5-cm smooth, raised, ulcerated, and firm mass was present ventral and lateral to the dorsal fin on the left body wall. Whole-body CT images obtained before and after contrast administration revealed an encapsulated, homogeneous, fat-opaque mass within the muscle. The mass was fat echoic with poor vascularity on ultrasonographic examination. Histologic evaluation of an ultrasound-guided needle biopsy specimen was suggestive of a lipoma.
TREATMENT AND OUTCOME
The mass was excised, and the fish was placed in water with 0.3% salinity for 3 weeks after surgery. Postoperative antimicrobial administration was not indicated, and additional postoperative analgesic administration was considered impractical. The patient had noticeable improvement in appetite and activity with no indication of discomfort immediately following surgery. Five weeks after surgery, the incision site had healed with minimal scarring, and evaluation of CT images revealed no evidence of mass regrowth or regional osteomyelitis.
Antemortem evaluation and diagnosis of a lipoma in a teleost with subsequent excision was described. This report highlighted the logistic challenges associated with anesthesia, advanced diagnostic imaging, and surgery in fish and showed that they can be successfully overcome so that high-level medical care can be provided to such patients.
