{"title":"Clinical and magnetic resonance imaging findings of presumed limber tail syndrome in a cat.","authors":"Marie Avril, Anne-Sophie Bedu, Thibaut Troupel","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>A 4-year-old neutered female domestic shorthair indoor cat was presented with sudden onset of abnormal and painful tail-carriage. The tail was held horizontally for the first centimeters from the base and a flaccid paralysis was evident more distally. Magnetic resonance imaging of the lumbosacral spine and tail revealed a lesion located in the right <i>sacrocaudalis dorsalis lateralis</i> and <i>medialis</i> muscles along the 1st coccygeal vertebrae. The lesion was poorly defined, T2-weighted hyperintense, and T1-weighted isointense compared to surrounding and contralateral muscles and had a strong homogeneous contrast enhancement. The cat began receiving prednisolone and clinical signs progressively improved and disappeared within 2 wk. Clinical presentation and MRI findings were comparable to those previously described in dogs with limber tail syndrome. To the best of our knowledge, limber tail syndrome has not been reported in cats. However, based on this case, we inferred that limber tail syndrome may occur in cats. Key clinical message: Limber tail syndrome could be considered among the differential diagnoses in both dogs and cats presented with acute and flaccid tail paralysis. Limber tail syndrome is essentially a clinical diagnosis. An animal with suspected limber tail syndrome should initially be treated conservatively and, if no improvement or further deterioration are observed, MRI could be considered to refine the diagnosis, as it allows identification of tail muscles and can detect lesions affecting these structures.</p>","PeriodicalId":9429,"journal":{"name":"Canadian Veterinary Journal-revue Veterinaire Canadienne","volume":"66 1","pages":"40-45"},"PeriodicalIF":0.9,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11705180/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142944962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Hepatic <i>Mycobacterium heckeshornense</i> infection in a dog with cavitary lung disease.","authors":"Siheng Xie, Bernard Seguin, Lisa Brownlee, Manuel Boller","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>A 9-year-old neutered male cairn terrier dog was initially presented because of inappetence, increased respiratory effort, and occasional coughing. A cavitary lung mass was diagnosed using CT and removed with lung lobectomy. Histopathology of the mass revealed necrosuppurative inflammation with acid-fast rod bacteria in macrophages, with <i>Mycobacterium</i> spp. a possible cause. Routine bacterial culture of a lung-lesion swab was negative for growth. The dog improved and did not show any clinical signs for 9 mo after the surgery, at which time a second recheck CT scan and bloodwork revealed diffuse hepatopathy and peritoneal effusion. The dog was hospitalized 3 d after this recheck because of signs of acute abdomen with vomiting, melena, polyuria, and polydipsia. Cytology of liver fine-needle aspirates revealed marked pyogranulomatous inflammation with acid-fast rod bacteria in histiocytes; phylogenetic analysis of hsp65 PCR amplicons from that tissue identified sequences identical to <i>Mycobacterium heckeshornense.</i> No other bacteria were isolated on a routine bacterial culture of a liver swab. Hepatic mycobacteriosis was treated with long-term enrofloxacin, clarithromycin, and doxycycline. The dog improved slowly, and the liver enzymes returned to normal after 4 mo of treatment. This is the first reported case of <i>M. heckeshornense</i> infection in a dog. Diseases caused by non-tuberculous mycobacteria such as <i>M. heckeshornense</i> are generally not reportable due to low risk of transmission between and to humans, but the zoonotic potential warrants further research in the future. Key clinical message: Dogs without overt immunodeficiency can be at risk of <i>M. heckeshornense</i> infection and can develop life-threatening pathology affecting multiple organs. However, clinical resolution can be achieved even in a severely affected dog. If <i>Mycobacterium</i> is suspected, it is important to consult with diagnostic laboratories to ensure correct samples are obtained and correct analytical procedures are used.</p>","PeriodicalId":9429,"journal":{"name":"Canadian Veterinary Journal-revue Veterinaire Canadienne","volume":"66 1","pages":"28-34"},"PeriodicalIF":0.9,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11705168/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142945078","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
