An 8-year-old intact male Belgian Malinois, weighing 37.2 kg, was referred for evaluation due to right side facial paresis, ataxia and a two-month history of decreased cognitive ability. Physical and neurological examinations revealed mild depression, left-sided head tilt, right-sided facial paresis and ataxia. A well-demarcated, broad-based cerebellar mass and hyperostosis were found on CT imaging of the brain. Based on these CT findings, a cerebellar meningioma was strongly suspected. Hydroxyurea and prednisolone were administered; after 4 weeks, there was reduction in mass size as compared to initial CT results. However, the mass size was found to have grown 6 weeks after hydroxyurea treatment. We then prescribed a combination of imatinib mesylate and hydroxyurea. Two weeks following combination treatment, the mass size had reduced significantly. The mass continuously decreased in size until the patient died during anesthesia. Cerebellar transitional meningioma was confirmed by histopathologic examination. To the author’s knowledge, this is the first reported case of imatinib mesylate plus hydroxyurea therapy for the treatment of meningioma in veterinary medicine.

The present study aimed to investigate the technical feasibility of percutaneous endoscopic mini-hemilaminectomy via a uniportal approach, and to evaluate the possibility of decompression and endoscopic examination of the thoracic and lumbar spinal canals in small dogs during such procedures. Fresh canine cadavers of mixed-breed dogs (n=7) were used in this study. Following injection of a barium and agarose mixture (BA-gel) to stimulate intervertebral disc herniation, percutaneous endoscopic mini-hemilaminectomy was performed using a lateral approach to the thoracic and lumbar vertebrae. BA-gel was removed to decompress the spinal cord using an elevator and rongeurs after mini-hemilaminectomy. Pre and post-operative computed tomography (CT) scans were obtained to evaluate surgical outcomes. Intra-operative complications, incision length, and procedure time were recorded. All procedures were completed with clear visualization of the spinal cord and floor of the spinal canal. The mean total operating time was 58.00 ± 18.06 min. Lengths of incision were under 1 cm in all dogs. Intra-operative complications included iatrogenic nerve root injuries caused by the micro-rongeur in two dogs. CT imaging revealed that removal of BA-gel resulted in sufficient spinal cord decompression. Our findings indicated that percutaneous endoscopic thoracolumbar mini-hemilaminectomy is feasible for spinal cord decompression and allows for adequate observation of the spinal canal. Thus, this technique may be an alternative surgical option for treatment of thoracolumbar disk disease in dogs.

A 9-year-old castrated male Shih-tzu dog was referred to us because of chronic vomiting. The patient’s hematological, radiographic, ultrasonographic, endoscopic, and histological examinations were evaluated for diagnosis. Hematologic analysis indicated moderate anemia and azotemia. Based on imaging study, oval-shape mass was identified in gastric pylorus area. A proliferative mass was found on endoscopic examination and we performed biopsy using grasping forceps. The histopathological findings of the biopsy specimens indicated hypertrophic gastritis and Y-U pyloroplasty was performed. However, the histopathological examination of surgically resected mass was identified as tubular adenocarcinoma of stomach. Then carboplatin chemotherapy was performed 4 times for 13 weeks. The clinical sign such as vomiting were resolved gradually after surgery and chemotherapy, and the patient’s condition was managed favorably until recently (30 months after surgery). This case report demonstrated clinical features, imaging studies, endoscopic characteristics, histopathological and immunohistochemical features of gastric tubular adenocarcinoma as early gastric cancer in a dog.

A 4-year-old female Maltese (case 1), a 9-year-old castrated male Shih-Tzu (case 2) and 2-year-old female Pomeranian (case 3) were presented because of neurological signs such as head tilt, ataxia, circling and paresis. Three cases were tentatively diagnosed to meningoencephalitis of unknown etiology based on computed tomography scan and cerebrospinal fluid analysis. All patients were managed with cyclosporine plus prednisolone therapy. The survival times of three patients were 170, 70 and 21 days, respectively. After cases expired, we performed necropsy and histopathological examination for definitive diagnosis. Based on the necropsy, histopathological and immunohistochemical examinations, case 1, 2 and 3 were definitely diagnosed to necrotizing meningoencephalitis, necrotizing leukoencephlaitis and granulomatous meningoencephalitis, respectively. This case report demonstrated that the clinical findings, brain CT characteristics, histopathological and immunohistochemical features of NME, NLE and GME in dogs and discussed about the reason of relatively short survival times under cyclosporine plus prednisolone therapy.
