A 9‐year‐old Simmental cow presented with watery diarrhoea, crusty skin lesions, loss of appetite and hepatomegaly. Suspecting severe liver disease, the cow was euthanased due to poor prognosis. During gross postmortem examination, large numbers of multifocal to coalescing nodules often with soft necrotic centres ranging from miliary to 7 cm in size were present in the liver, lung, mesentery, peritoneum and lymph nodes. These features were suggestive of bovine tuberculosis. However, direct tissue smears stained by Ziehl Neelsen stain were negative for the presence of acid‐fast bacteria, and subsequent histopathological and immunohistochemical investigations confirmed the presence of metastasizing cholangiocarcinoma. This case reminds clinicians and pathologists to keep an open mind during the diagnostic process and serves to highlight the value of histopathology in diagnosing seemingly characteristic gross lesions.","PeriodicalId":23496,"journal":{"name":"Veterinary Record Case Reports","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142247956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our objective was to evaluate epidural efficacy before surgery using nociceptive threshold measurement. Nociceptive thresholds were measured with transdermal electrical stimulation via the Dolosys Pain Tracker device. The dog received epidural ropivacaine and morphine, resulting in a cessation of withdrawal response and electromyographic activity. This effect was confirmed under anaesthesia. Postoperatively, the dog recovered without relevant complications. In conclusion, nociceptive threshold measurement using the Dolosys Pain Tracker device allowed immediate confirmation of epidural efficacy, reducing the risk of intraoperative analgesic inadequacy. This approach may enhance surgical pain management in challenging cases.","PeriodicalId":23496,"journal":{"name":"Veterinary Record Case Reports","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142247959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There was no evidence of mass recurrence, and general and neurological examination remained normal at 9‐month follow‐up. While the majority of intraocular neoplasms are benign, a malignant neoplasm must be considered in all cases of intraocular mass. Differentiation between benign and malignant intraocular neoplasms is challenging and often requires enucleation with histopathology to confirm diagnosis. Tumour staging should be considered in the event of a malignant nerve sheath tumour. Finally, uveal malignant nerve sheath tumour should not only be considered in blue eyed dogs, but also in brown eyed dogs as in the present case.","PeriodicalId":23496,"journal":{"name":"Veterinary Record Case Reports","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2024-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142247996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three months later, the kitten re‐presented for investigation of acute onset ventral abdominal discomfort and bruising. On presentation, clinical examination revealed omphalitis and subcutaneous bruising, with no evidence of an umbilical stoma. Ultrasonography demonstrated a patent urachus communicating with the subcutaneous tissue space, resulting in accumulation of urine at the level of the umbilicus. A ventral midline coeliotomy was performed to allow resection of the urachal remnant, including a partial cystectomy.

Surgical stabilisation of the right shoulder arthrodesis was achieved with two 2.4 mm Synthes locking compression plates and two 2.4 mm inter‐fragmentary positional screws. Short‐term follow‐up indicated adequate bone healing with good alignment and implant integrity. Subsequent long‐term phone follow‐up 22 months after surgery revealed a successful outcome with no visible stiffness and only a mechanical lameness.
