A 14‐year‐old, female, blue‐fronted Amazon parrot was referred for episodes of regurgitation. The differential diagnosis mainly included bornavirus infection, infectious or traumatic ingluvitis, gastro‐oesophageal reflux, gastritis/enteritis, heavy metal poisoning, metabolic disease (severe hepatic or renal disease), coelomitis, digestive neoplasia, extra‐digestive masses, organomegaly or foreign body. No improvement was noted with symptomatic treatment. Radiographs, avian bornavirus polymerase chain reaction and serology, biochemistry, haematology, crop cytology and ultrasonography failed to provide a definitive diagnosis. Lethargy, weight loss and crop stasis after 1 month motivated computed tomography, which revealed focal thickening of the oesophageal wall. Fine‐needle aspiration under computed tomography guidance of the mass was non‐diagnostic, and the bird died during recovery from anaesthesia. Oesophageal squamous cell carcinoma was confirmed by histopathology. This case illustrates the benefit of advanced diagnostic imaging to investigate chronic refractory regurgitations and describes the use of computed tomography‐guided fine‐needle aspiration in an avian patient.

Cases with a fracture of the os penis in dogs have been reported rarely, and to the authors’ knowledge, traumatic penile amputation has only been reported once. The dog presented in this case report sustained subtotal traumatic penile amputation of unknown origin. Before the presentation, the dog had been in a boarding facility, where no trauma was witnessed. The patient presented with haematuria, discharge from the prepuce, and lethargy. Upon examination, traumatic subtotal penile amputation was diagnosed, and a complete blood count revealed severe regenerative anaemia. Surgical debridement was performed, and the wound healed by second intention. During the recovery period, a urinary catheter was placed to aid in preventing urethral stenosis. Though the animal sustained extensive trauma to its genitals and subsequent anaemia, it survived with a good quality of life and acceptable urinary function.

A 2‐year‐old, female neutered, Labrador Retriever dog was presented with left otalgia. Otoscopic examination revealed a blind ending left external ear canal. Magnetic resonance imaging confirmed an abrupt narrowing of the lateral aspect of the horizontal canal, medial to which the remaining horizontal ear canal and middle ear cavities contained well‐delineated, homogenous, T2w, fluid‐attenuated inversion recovery and T1w hyperintense, non‐contrast enhancing material. A diagnosis of external auditory canal atresia was made based on the imaging findings. Considering the patient's age and absence of preceding trauma, a congenital cause was considered most likely. Surgical treatment by way of a total ear canal ablation with lateral bulla osteotomy was performed. At the re‐check appointment, the surgical site had healed well and there were no associated complications noted; a telephone call with the owner 5 months later documented no clinical concerns.

Multiple closely associated fibroepithelial polyps, also known as acrochordonous plaques, are benign proliferative lesions, described so far only on the dorsal neck and the head of bulldogs and pugs, and on the lumbo‐sacral region of a dobermann. Here, we report for the first time the presence of multiple closely associated fibroepithelial polyps in the external ear canal of three French bulldogs with chronic otitis. In all the cases, lesions presented as a plaque composed of domed shaped, villous or filiform proliferations. The diagnosis was obtained combining video‐otoscopic and histopathological findings. In only one case, these lesions were considered critical for the persistence of the otitis externa, and surgical treatment was recommended. Multiple closely associated fibroepithelial polyps should be set among the differential diagnoses of plaque‐like lesions with an irregular surface in the external ear canal of French bulldogs.

An adult yellow‐footed female tortoise (Chelonoidis denticulata) weighing 7.6 kg was voluntarily surrendered to the environmental police. The history‐taking could not be obtained due to a lack of information. Upon physical examination, a fluid‐filled structure prolapsed through the cloacal opening was observed. The aspirated fluid had a citrine‐yellow colour, suggesting urinary bladder prolapse, which was successfully reduced back into the coelomic cavity with the hydrostatic reduction technique. The following day, prolapse recurrence was observed. In addition, distal two‐thirds of the organ had a darkened coloration. Whole‐body radiographs revealed four eggs ready for oviposition. Partial cystectomy of the prolapsed urinary bladder was done. Pretreatment with calcium followed by oxytocin was used for nonobstructive egg retention, and all eggs were laid. After 2.4 years of the surgery, the tortoise did not experience a recurrence of bladder prolapse.

A 4‐month‐old male domestic shorthair cat with a 36‐h history of acute and progressive painful paraplegia was referred. The neurological examination was consistent with T3‒L3 myelopathy. Magnetic resonance imaging of the thoracolumbar region revealed an extradural mass at the level of T12‒T13 that caused moderate spinal cord compression. The cat underwent T12‒T13 dorsal laminectomy decompressive surgery, and its neurological signs improved shortly after surgery. A diagnosis of epidural spinal steatitis was reached based on histopathological examination of the compressive mass. To the authors’ best knowledge, this is the first description of the magnetic resonance imaging and computed tomographic findings of histopathologically confirmed idiopathic sterile pyogranulomatous inflammation of epidural fat in a cat. Epidural idiopathic sterile pyogranulomatous steatitis should be included as a possible differential diagnosis in young cats with acute and progressive T3‒L3 myelopathy signs.

Perineal urethrostomy was carried out in a Golden Guernsey goat to relieve urethral obstruction associated with urethral calculi. The surgery was successful, but post‐surgical complications developed, including haemorrhage and failure of the penile stump to heal. Revision surgeries were carried out with a successful surgical resolution. Bacterial cystitis subsequently developed, and Proteus spp. and Trueperella pyogenes were identified. Treatment of the bacterial cystitis proved challenging, and intense management was required. Survival post‐surgery was over 3.5 years.

An 8‐h‐old Arabian foal was presented for evaluation of progressive weakness since birth. The foal presented laterally recumbent with pale and muddy mucous membranes, a grade III/VI left basilar murmur, and an irregularly, irregular rhythm. Transthoracic echocardiogram along with an electrocardiogram (EKG) was performed. Atrial fibrillation was recorded throughout the examination. The left and right atria were both significantly enlarged. A right to left shunt across the atrial septum was confirmed via an intravenous injection of agitated saline. The tricuspid valve was rudimentary without apparent atrioventricular flow and no ventricular septal defect was appreciated. The animal was euthanased, and necropsy found dysplasia of the tricuspid valve, a hypoplastic right ventricle with pulmonary valve atresia, and an intact ventricular septum. This condition is similar, both haemodynamically and in terms of prognosis, to tricuspid atresia, which has been described previously in Arabian foals, with the exception that there is the complete absence of connection between the atrium and ventricle in the case of tricuspid atresia. Of 14 previously reported cases of tricuspid atresia in neonatal foals, nine were Arabian foals. Further investigation into the possibility of hypoplastic right ventricle as a familial condition in the Arabian breed should be considered.
一匹 8 h 大的阿拉伯小马驹因出生后逐渐虚弱而前来就诊。小马驹呈侧卧位，粘膜苍白浑浊，左基底动脉杂音为 III/VI 级，心律不齐。医生对其进行了经胸超声心动图检查和心电图检查。整个检查过程都记录到心房颤动。左心房和右心房均明显增大。通过静脉注射生理盐水，确认了房间隔存在右向左分流。三尖瓣不发育，没有明显的房室血流，也没有发现室间隔缺损。动物被安乐死，尸体解剖发现三尖瓣发育不良，右心室发育不良，肺动脉瓣闭锁，室间隔完整。这种情况在血流动力学和预后方面都类似于三尖瓣闭锁，而三尖瓣闭锁曾在阿拉伯马驹中出现过，不同之处在于三尖瓣闭锁的病例心房和心室之间完全没有连接。在之前报道的 14 例新生马驹三尖瓣闭锁病例中，有 9 例是阿拉伯马驹。应考虑进一步调查阿拉伯种马右心室发育不全是否可能是一种家族性疾病。

An 8‐year‐old, female, neutered labrador retriever presented for surgical excision of a subcutaneous mast cell tumour and extirpation of the right inguinal and right medial iliac lymph nodes. Histology confirmed a completely excised, low mitotic count subcutaneous mast cell tumour with lymph node metastasis. Vinblastine and prednisolone were administered as adjunctive chemotherapy. Six weeks post‐operatively, the dog presented dehydrated, tachycardic and pyrexic, with haematochezia, vomiting and abdominal pain. Coeliotomy revealed a communication between the jejunum and the proximal right ureter, with no obvious aetiology identified. Right ureteronephrectomy was performed, with debridement and closure of the affected jejunum. Histopathology reported a subacute to chronic neutrophilic and necrohaemorrhagic pyelonephritis and haemolytic Escherichia coli, resistant to amoxicillin clavulanate, was cultured. The dog recovered and re‐started the chemotherapy protocol following restaging 2 months post‐operatively. Unfortunately, 7 weeks after starting this protocol, the patient developed acute necrotising pancreatitis following dietary indiscretion and was electively euthanased.

A 10‐year‐old male neutered Bichon Frise presented for assessment of right unilateral exophthalmos. The ophthalmological assessment revealed signs of retrobulbar disease. Computed tomography of the head showed a cavitary, well‐defined, fluid‐filled structure, which displayed a strong peripheral rim of contrast enhancement, and was centred around the tooth roots of the right maxillary first and second molar teeth (109 and 110). Focused ultrasound‐guided fluid sampling and fine needle aspirates were obtained for diagnostic purposes. After discussing the case with a veterinary dentist, extraction of the 109 and 110 and debridement of the cyst were performed. Histopathology supported the suspicion of a radicular cyst. Radicular cysts, despite being benign lesions, need to be included as a possible differential in cases with exophthalmos due to their potential retrobulbar mass effect.
