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.

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.

The purpose of this study was to assess the normal distribution of 18F-fluoro-2-deoxy-D-glucose (FDG) uptake of canine brain structures using a high-resolution research tomography-positron emission tomography (HRRT-PET) and 7 T-magnetic resonance imaging (MRI) fusion system. FDG-PET and T2-weighted MRI of the brain were performed on 4 healthy laboratory beagle dogs. On MRI, regions of interests (ROIs) were manually drawn over 51 intracranial structures, including nine gross structures and 42 detailed structures. Relative standard uptake value ratio (rSUV=SUV of ROI/SUV of whole brain) was calculated for each ROI. The HRRT-PET and 7 T-MRI fusion imaging system demonstrated significant differences in glucose metabolism among various intracranial structures. Among gross structures, the midbrain and the pons and medulla oblongata had the highest uptake (rSUV: 1.12 ± 0.03) and lowest uptake (rSUV: 0.90 ± 0.06) of FDG, respectively. When rSUVs were calculated on detailed regions, the caudal colliculus and the longitudinal fibers of pons had the highest (rSUV: 1.62 ± 0.05) and the lowest (rSUV: 0.63 ± 0.03) glucose metabolism, respectively. Because the high resolution of PET-MRI fusion images provided clearly identifiable metabolic activities of canine brain, the HRRT-PET and 7 T-MRI fusion imaging might be a good tool for evaluation of intracranial diseases in canines.

A 4-year-old intact female Pekingese dog was presented with ataxia and seizure episodes. Based on magnetic resonance imaging and cerebrospinal fluid analysis results, meningoencephalitis of unknown etiology was suspected. The present case survived for 1,096 days under cyclosporine plus prednisolone therapy and was definitively diagnosed with necrotizing meningoencephalitis. This report describes the clinical findings, serial magnetic resonance imaging characteristics and pathologic features of a necrotizing meningoencephalitis and long-term survival after cyclosporine with prednisolone therapy.
