Background

In ferrets, osteomas are rare, benign bone-originating tumors that can lead to detrimental clinical signs which negatively impact their quality of life. To date, current reported successful treatments include complete surgical excision for curative intent. Surgical debulking and subsequent radiotherapy was a novel approach to treatment employed in this case.

Case description

A 10-month-old, neutered male, sable ferret (Mustela putorius furo) presented with a firm, immobile, subcutaneous mass (15.6 mm x 14.0 mm x 16.0 mm; rostrocaudal x mediolateral x dorsoventral) originating from the lateral margin of the angle of the left mandible based on computed tomographic (CT) scan. Surgical debulking was performed and the mass was confirmed to be an osteoma on histopathology. To follow, stereotactic radiotherapy was prescribed to treat the residual mandibular mass effect with 8 Gy delivered each day for 3 sequential days (total dose of 24 Gy). There were no apparent early or late adverse effects of radiation and no regrowth was appreciated clinically or on CT scans 141 days post-surgery (106 days post-radiotherapy) and 403 days post-surgery (368 days post-radiotherapy). The ferret died approximately 2 years post-operation due to unknown cause without obvious regrowth of the mandibular mass at the time of death.

Conclusions and case relevance

In this ferret, the combination of surgical debulking and stereotactic radiotherapy resulted in a clinical cure of a mandibular osteoma for at least 2 years. Additional studies with a larger sample size may further elucidate early and late radiation side effects, surgical complications, and long-term outcome.

在雪貂中，骨瘤是一种罕见的良性骨源性肿瘤，可导致有害的临床症状，并对其生活质量产生负面影响。迄今为止，目前报道的成功治疗方法包括完全手术切除以达到治愈目的。手术切除和随后的放射治疗是本病例采用的新治疗方法。病例描述：一只10个月大的绝育雄性貂（鼬鼬），在计算机断层扫描（CT）的基础上，出现了一个坚固的、不可移动的皮下肿块（15.6 mm x 14.0 mm x 16.0 mm；背侧x中外侧x背腹侧），起源于左下颌骨角外侧边缘。手术切除后病理证实肿块为骨瘤。随后，采用立体定向放疗治疗下颌残余肿块效应，每天8 Gy，连续3天（总剂量24 Gy）。放疗后141天（放疗后106天）和403天（放疗后368天）的临床和CT扫描均未发现肿瘤再生。雪貂术后约2年死亡，死因不明，死亡时下颌肿块未见明显再生。结论与病例相关性：在本病例中，手术切除和立体定向放疗相结合，使患者临床治愈了至少2年的下颌骨瘤。更多样本量更大的研究可能会进一步阐明早期和晚期放射副作用、手术并发症和长期结果。

Background

Cardiac troponin I (cTnI), a cardiac-specific biomarker used to detect myocardial injury in mammals, has only undergone cursory investigation in reptiles. This study’s objectives were to determine feasibility of cTnI detection in reptilian cardiac tissue, skeletal muscle, and plasma utilizing two different immunoassays, and compare tissue concentrations between immunoassays and taxonomic groups (chelonians, lizards, snakes).

Methods

Tissue homogenates were created and total protein concentrations determined from cardiac tissue and skeletal muscle collected from 30 individual reptiles representing 25 different species. Heparinized plasma was collected from seven reptiles. Samples were analyzed on both point-of-care (i-STAT) and high-sensitivity (ADVIA) immunoassays when feasible, and standardized concentrations compared between sample type, immunoassay, and taxonomic group.

Results

cTnI was detected above the lower limit of detection (LoD) in cardiac tissues from 24/25 species on the i-STAT and 22/22 species on the ADVIA. Only one sample produced analyzer error, occurring on the i-STAT. Cardiac tissue had significantly higher cTnI in chelonians (p_adj = 0.034) and lizards (p_adj = 0.049) than snakes on the i-STAT, and in chelonians than both lizards (p_adj = 0.015) and snakes (p_adj < 0.01) on the ADVIA. The i-STAT and ADVIA had poor agreement for cardiac tissue samples. Most skeletal muscle samples reported analyzer error (20/30) or concentrations below the LoD (9/30) on the i-STAT. On the ADVIA all skeletal muscle samples were above the LoD (25/25), and four snakes had higher cTnI concentrations in skeletal muscle than cardiac tissue. All plasma samples had detectable cTnI on both immunoassays, but most on the i-STAT were below the LoD.

Conclusions and clinical relevance

At least 22 reptile species have detectable cTnI in cardiac tissue on two different immunoassays. Due to variability between taxonomic groups and immunoassays, establishment of both species-specific and assay-specific reference intervals are warranted for clinical utility.

心肌肌钙蛋白I （cTnI）是一种用于检测哺乳动物心肌损伤的心脏特异性生物标志物，在爬行动物中只进行了粗略的研究。本研究的目的是确定利用两种不同的免疫分析法在爬行动物心脏组织、骨骼肌和血浆中检测cTnI的可行性，并比较免疫分析法和分类类群（龟类、蜥蜴、蛇）之间的组织浓度。方法建立组织匀浆，测定取自25种30只爬行动物的心脏组织和骨骼肌的总蛋白浓度。从7只爬行动物身上采集肝素化血浆。在可行的情况下，采用即时护理（i-STAT）和高灵敏度（ADVIA）免疫分析法对样品进行分析，并在样品类型、免疫分析法和分类组之间进行标准化浓度比较。结果在i-STAT上24/25种和ADVIA上22/22种的心脏组织中，sctni均高于检测下限（LoD）。只有一个样本产生分析器错误，发生在i-STAT上。在i-STAT上，龟类（padj = 0.034）和蜥蜴（padj = 0.049）的心脏组织cTnI显著高于蛇，在ADVIA上，龟类的心脏组织cTnI显著高于蜥蜴（padj = 0.015）和蛇（padj < 0.01）。i-STAT和ADVIA对于心脏组织样本的一致性较差。大多数骨骼肌样本报告分析仪误差（20/30）或浓度低于i-STAT上的LoD（9/30）。在ADVIA上，所有骨骼肌样本都高于LoD(25/25)，并且有四条蛇的骨骼肌中的cTnI浓度高于心脏组织。所有血浆样品在两种免疫分析中均可检测到cTnI，但大多数i-STAT低于LoD。结论及临床意义至少22种爬行动物在两种不同的免疫分析中可检测到心脏组织中的cTnI。由于分类组和免疫测定之间的差异，建立物种特异性和测定特异性参考区间是临床应用的必要条件。

Background

Ectopia cordis is a congenital malformation characterized by the partial or complete externalization of the heart through a defect in the body wall, typically resulting from a failure of midline fusion during embryogenesis. Ectopia cordis is a rare anomaly found in humans, livestock, and companion animals, with only a few documented cases in reptiles.

Case description

This report details the successful surgical correction of ectopia cordis in a neonatal ball python (Python regius). The python was presented immediately posthatching, with the heart located completely outside of the body cavity but in the correct mid-cervical anatomical position. The heart and pericardium were macroscopically unremarkable, except for the presence of reactive fibrinous deposits on the pericardial serosa. Echocardiography confirmed normal cardiac morphology and function without septal or valvular abnormalities. After excision of the fibrin, repositioning of the heart into the coelomic cavity and closure of the body wall were performed. Postoperatively, the python received antimicrobial prophylaxis, supportive care, and remained hospitalized until the first ecdysis and spontaneous feeding were observed. During a one-year follow-up period, the python showed normal feeding behavior and a comparable length and body weight to its clutchmate. Repeated echocardiographic examinations demonstrated normal cardiac function, with no evidence of fibrotic pericardial adhesions.

Conclusions and case relevance

This report documents the first successful treatment of ectopia cordis in a reptilian species, and represents only the third such case described in the veterinary literature.

心外翻是一种先天性畸形，其特征是心脏通过体壁缺陷部分或完全外翻，通常是由于胚胎发生时中线融合失败造成的。心异位是一种罕见的异常，在人类，家畜和伴侣动物中发现，只有少数记录的爬行动物病例。病例描述：本报告详细介绍了新生儿球蟒（巨蟒）心脏异位的成功手术矫正。这条蟒蛇立即被呈现，心脏完全位于体腔外，但在正确的颈中解剖位置。除了心包浆膜上有反应性纤维沉积外，心脏和心包在宏观上不明显。超声心动图证实心脏形态和功能正常，无间隔或瓣膜异常。切除纤维蛋白后，将心脏重新定位到体腔内并关闭体壁。术后，蟒蛇接受抗菌预防治疗和支持性护理，并一直住院，直到观察到第一次蜕皮和自发进食。在一年的随访期间，蟒蛇表现出正常的摄食行为，其长度和体重与其配偶相当。多次超声心动图检查显示心功能正常，无纤维化心包粘连的证据。结论和病例相关性：本报告是首例成功治疗爬行动物心异位的病例，也是兽医文献中第三例此类病例。

Background

Middle ear diseases are commonly observed in guinea pigs. However, due to the small anatomical structures and the need for anaesthesia, X-ray diagnostics are often risky for the patients and offer limited diagnostic value. This study aimed to describe CT abnormalities of the outer, middle and inner ear and to determine the prevalence of ear diseases in guinea pigs. Additionally, the study evaluated potential predisposing factors for ear abnormalities, such as age, breed and other head pathologies.

Methods

Medical records of guinea pigs that had undergone CT scans between June 2020 and July 2025 were retrospectively reviewed and categorized based on the indication for the CT scan (i.e., ear-related clinical signs vs nonear related conditions). Each CT study was assessed for abnormalities in the ears, upper respiratory tract, dentation and – in the case of full-body CT studies – the thorax and abdomen.

Results

CT scans of 55 guinea pigs were analysed. Sixteen guinea pigs (29.09%) exhibited changes in a total of 25 middle ears (25/110). From the age of 5.6 years onward, middle ear pathologies were consistently bilateral and involved both the dorsal and ventral bullae. The prevalence of middle ear disease increased significantly with age. Additionally, 3 guinea pigs (5.45%) showed abnormalities in the external ear canal and cochlea. A correlation was found between middle ear pathologies and ipsilateral dental disease.

Conclusions and clinical relevance

CT is a reliable imaging modality for detecting ear abnormalities in guinea pigs. Notably, 54 out of 55 animals underwent CT scanning without the need for general anaesthesia. The findings indicate that ear pathologies are common in guinea pigs, although their clinical relevance remains uncertain.

背景：中耳疾病在豚鼠中很常见。然而，由于解剖结构小，需要麻醉，x线诊断对患者来说往往是有风险的，诊断价值有限。本研究旨在描述豚鼠外耳、中耳和内耳的CT异常，并确定耳部疾病的患病率。此外，该研究还评估了耳朵异常的潜在易感因素，如年龄、品种和其他头部病变。方法回顾性分析2020年6月至2025年7月期间接受CT扫描的豚鼠病历，并根据CT扫描的适应症（即耳部相关临床体征与非耳部相关病症）进行分类。每一项CT研究都评估了耳朵、上呼吸道、牙列的异常，在全身CT研究的情况下，评估了胸部和腹部的异常。结果分析了55只豚鼠的ct扫描结果。16只豚鼠（29.09%）共25只中耳（25/110）出现变化。从5.6岁开始，中耳病变一直是双侧的，并累及背侧和腹侧大泡。中耳疾病的患病率随着年龄的增长而显著增加。3只（5.45%）豚鼠出现外耳道及耳蜗异常。发现中耳病变与同侧牙病之间存在相关性。结论和临床意义ect是一种可靠的检测豚鼠耳部异常的成像方式。值得注意的是，55只动物中有54只在不需要全身麻醉的情况下进行了CT扫描。研究结果表明，耳部病变在豚鼠中很常见，尽管其临床相关性尚不确定。

Dystocia secondary to ectopic pregnancy in a Kenyan sand boa (Eryx colubrinus) 肯尼亚沙蟒异位妊娠继发难产

IF 0.6 4区农林科学 Q4 VETERINARY SCIENCES

Journal of Exotic Pet Medicine

Pub Date : 2026-01-01 Epub Date: 2025-12-26 DOI: 10.1053/j.jepm.2025.12.006

Background

This is the first published description of successful surgical management of dystocia secondary to ectopic pregnancy in a Kenyan sand boa.

Case description

A 7-year-old intact female Kenyan sand boa (Eryx colubrinus) presented with a history of unusual behavior and the passage of 7 infertile ova 3 days prior. On physical examination, coelomic palpation revealed fluid distention and multiple firm structures in the mid-to-caudal coelom. Radiographs revealed homogeneous fluid and or soft tissue distention of the coelomic cavity, with multifocal ill-defined heterogenous mineral opacities in the central and caudal thirds of the body, interpreted as fetuses. The following day, exploratory surgery confirmed the presence of coelomic effusion and necrotic ectopic fetuses. Extensive flushing and debridement were performed, followed by ovariosalpingectomy. Postsurgical radiographs revealed additional fetuses remaining in the caudal third of the coelomic cavity. A revision procedure was performed, and the remaining fetuses were successfully removed. One year after initial presentation, the snake remains healthy with no further health concerns.

Conclusion and case relevance

Dystocia and ectopic pregnancy are rarely reported in viviparous reptiles. Dystocia secondary to ectopic pregnancy should be considered as a differential in viviparous reptiles presented with health and reproductive concerns.

背景：这是肯尼亚沙蟒异位妊娠难产成功手术治疗的首次报道。病例描述：1例7岁完整雌性肯尼亚沙蟒（Eryx colubrinus）， 3天前出现异常行为史和7个不孕卵子。体格检查时，体腔触诊显示体腔中尾部有液体扩张和多个坚固的结构。x线片显示体腔均匀的液体和/或软组织扩张，在身体的中央和尾部三分之一处有多灶不明确的异质矿物混浊，解释为胎儿。第二天，探查手术证实存在体腔积液和坏死性异位胎儿。进行了广泛的冲洗和清创，随后进行了卵巢输卵管切除术。术后x线片显示额外的胎儿留在体腔尾三分之一处。进行了翻修手术，成功地取出了剩余的胎儿。在初次出现一年后，蛇仍然健康，没有进一步的健康问题。结论：在胎生爬行动物中，宫外孕和宫外孕的发生率较低。继发于异位妊娠的难产应被认为是胎生爬行动物出现健康和生殖问题的差异。

Postsurgical radiographs revealed additional fetuses remaining in the caudal third of the coelomic cavity. A revision procedure was performed, and the remaining fetuses were successfully removed. One year after initial presentation, the snake remains healthy with no further health concerns.</div></div><div><h3>Conclusion and case relevance</h3><div>Dystocia and ectopic pregnancy are rarely reported in viviparous reptiles.
