An 11-year-old female cat presented for chronic vomiting. Endoscopy revealed an altered gastric mucosa and spontaneous formation of linear gastric tears during normal organ insufflations. The histopathological diagnosis was atrophic gastritis with Helicobacter pylori infection. Medical treatment permitted a complete resolution of clinical signs. The linear tears observed resembled gastric lesions rarely reported in humans, called "Mallory-Weiss syndrome". To the authors' knowledge this is the first report of spontaneous linear gastric tears in animals.

A five-year-old male Persian cat was referred for chronic weight loss, polyphagia and clay-coloured voluminous stools. Serum biochemistry showed elevated liver enzyme activity, hypocholesterolaemia and hypocobalaminaemia. On abdominal ultrasound, a thickened small intestinal wall and tortuous biliary tract were detected. Surgical biopsies of the small intestine, liver and pancreas with concurrently low serum trypsin-like immunoreactivity allowed a final diagnosis of pancreatitis, inflammatory bowel disease, cholangiohepatitis and exocrine pancreatic insufficiency. The cat was treated with antibiotics, prednisolone, oral pancreatic enzymes and parenteral cobalamin. At one-year follow-up, medical treatment has led to a complete resolution of clinical signs.

The medical records of 14 Italian wolves (Canis lupus italicus) with a vertebral fracture or luxation (SFL) between C1 and L7 treated at Ospedale Veterinario San Michele from 2017 and 2022 were reviewed. The most common cause of SFL was “road traffic accident”. Neurological signs were graded from 0 to 6 using a modified Frankel scale. Spinal fractures occurred in C1–C5 in 1 case, in T3–L3 in 11 cases and in L4–L7 in 2 cases. Six wolves were euthanized without treatment because they presented paraplegia without deep pain perception (DPP). Two animals with motor function were treated conservatively, and later on one of them was euthanized because of neurological impairment. Six wolves were surgically treated. Seven wolves had good neurological recovery, and six of them were released into the wild. Our results suggest that wolves with DPP before surgery may have a good functional recovery.

An adult neutered male Bengal tiger (Panthera tigris tigris) presented with abnormal gait. Neurological examination showed poor left ambulatory hemiparesis, spontaneous proprioceptive deficit in the left anterior limb, and decreased flexor reflex in the forelimbs. The neurological symptoms suggested a caudal cervical spinal cord lesion. Pathological findings included increased cholinesterase and protein levels in the cerebrospinal fluid. Computed tomography examination revealed C2-C3 intervertebral disc herniation, C5-C6 intervertebral disc herniation associated with a reduction of the intervertebral space, and mild ventral dislocation of the C6 vertebra compared to C5. In addition, severe bilateral shoulder osteoarthritis and a hypoattenuating nodule in the left thyroid gland with an open etiology were observed. These findings were interpreted as indicating cervical spondylomyelopathy (CSM). Treatment included analgesic and steroidal anti-inflammatory therapy as well as movement restriction. Follow-up at 4 weeks showed modest improvement. Thus, CSM should be included in the differential diagnosis of tigers with neurological cervical signs.
