The head and cranial portion of the neck of a 1-week-old sexually intact male polycerate (multihorned; 4-horned in this case) Jacob sheep (Ovis aries), the product of a 4-horned ram and a 4-horned ewe breeding, was presented for postmortem examination. The lamb had been born weak and unable to stand. Gradually, the animal lost its ability to eat and died shortly after. This lamb was 1 in a set of triplets. Within the triplet group, 1 lamb was born dead (horn number not specified) and 1 male 4-horned lamb was clinically normal. Breeding of this sire to
A 2-year-old 340-g sexually intact male bearded dragon (Pogona vitticeps) that was a red morph was referred because of a 1-month history of vomiting and regurgitation and a 1-day history of hematemesis. The animal had been mildly lethargic and inappetent after exiting brumation. Blood work performed by the referring veterinarian revealed severe leukocytosis (32.3 X 103 WBCs/μL; reference range,1 1.45 X 103 to 19.0 X 103 WBCs/µL) and severe hyperglycemia (1,339 mg/dL; reference range,2 108 to 333 mg/dL). Results were negative for a direct fecal smear and
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.
