Abstract

Abstract A 2-yr-old female bearded dragon (Pogona vitticeps) presented to the clinic exhibiting lameness and significant swellings bilaterally in the carpal region. On physical examination the lizard was determined to be in obese body condition and pododermatitis was observed on the palmar aspects of both carpi. The rest of the examination was unremarkable. Radiographs revealed opacities present in both carpal joints with possible fluid accumulation. Biochemistry revealed hypercalcemia and hyperphosphatemia. A joint aspirate was performed and submitted for cytology and culture. The sample was sterile and only inflammatory cells were seen. Despite these results, the swelling initially improved with daily lincomycin 5 mg/kg intramuscularly (IM) but recurred after 1 month, and the lizard was referred to a specialist center for further investigations. A tissue biopsy was performed and submitted for histology and culture. Histopathologic examination revealed periarticular soft tissue ectopic bone characterized by a proliferation of ectopic cartilage and both lamellar and woven bone with hematopoietically active bone marrow within a fibrous connective tissue stroma. Bacterial culture revealed a scant growth of Staphylococcus aureus and Serratia marcescens. The lizard received ceftazidime 20 mg/kg every 72 h IM for 3 wk. Clinical signs resolved until 8 months later when the swellings returned.
2岁大胡子龙腕骨上软组织异位骨化
摘要一只2岁的雌性须龙(Pogona vitticeps)向临床展示跛行和显着肿胀的双侧腕区。在体格检查中,这只蜥蜴被确定为肥胖的身体状况,并在两只腕部的掌部观察到足皮炎。考试的其余部分都很平常。x线片显示双侧腕关节混浊,可能有积液。生物化学显示高钙血症和高磷血症。进行联合抽吸并提交细胞学和培养。样品无菌,只见炎性细胞。尽管有这些结果,肿胀最初通过每日5 mg/kg肌肉注射林可霉素(IM)得到改善,但1个月后复发,蜥蜴被转到专家中心进行进一步调查。进行组织活检,并提交组织学和培养。组织病理学检查显示关节周围软组织异位骨,其特征是异位软骨、板层骨和编织骨增生,在纤维结缔组织基质中有造血活性的骨髓。细菌培养显示少量金黄色葡萄球菌和粘质沙雷氏菌生长。给予头孢他啶20 mg/kg,每72 h IM,连续3周。临床症状消退,直到8个月后肿胀复发。
