TLDR
It was found that lesion location was predictive of tumor type with diffuse cerebral or brainstem involvement predictive of lymphoma and third ventricle involved predictive of meningioma.Abstract:
The purpose of this study was to determine the frequency of different tumor types within a large cohort of cats with intracranial neoplasia and to attempt to correlate signalment, tumor size and location, and survival time for each tumor. Medical records of 160 cats with confirmed intracranial neoplasia evaluated between 1985 and 2001 were reviewed. Parameters evaluated included age, sex, breed, FeLV/FIV status, clinical signs, duration of signs, number of tumors, tumor location(s), imaging results, treatment, survival times, and histopathologic diagnosis. Most of the cats were older (11.3 +/- 3.8 years). Primary tumors accounted for 70.6% of cases. Metastasis and direct extension of secondary tumors accounted for only 5.6 and 3.8% of cases, respectively. Twelve cats (7.5%) had 2 or more discrete tumors of the same type, whereas 16 cats (10.0%) had 2 different types of intracranial tumors. The most common tumor types were meningioma (n = 93, 58.1%), lymphoma (n = 23, 14.4%), pituitary tumors (n = 14, 8.8%), and gliomas (n = 12, 7.5%). The most common neurological signs were altered consciousness (n = 42, 26.2%), circling (n = 36, 22.5%), and seizures (n = 36, 22.5%). Cats without specific neurological signs were common (n = 34, 21.2%). The tumor was considered an incidental finding in 30 (18.8%) cats. In addition to expected relationships (eg, meninges and meningioma, pituitary and pituitary tumors), we found that lesion location was predictive of tumor type with diffuse cerebral or brainstem involvement predictive of lymphoma and third ventricle involvement predictive of meningioma.read more

Canine intracranial primary neoplasia: 173 cases (1986-2003).
TL;DR: Based on the results of this study, thoracic radiographs and abdominal ultrasonography may be indicated to look for extracranial neoplasia prior to advanced imaging of the brain or intracranial surgery.

Feline lymphoma in the post-feline leukemia virus era
TL;DR: A significant decrease in the importance of FeLV-associated types of lymphoma in cats is confirmed and Associations of intestinal lymphoma and inflammatory bowel disease and diet should be further considered.

TL;DR: MRI is an excellent diagnostic tool for the detection of brain tumors in cats, and it provides important information to aid in the diagnosis of tumor type.

TL;DR: Treatment methods for meningiomas involve a combination of de-bulking surgery, chemotherapy and radiotherapy, and detailed accounts of several treatment protocols have been reported.

TL;DR: Improvements in treatment planning and radiation delivered to the tumor, while sparing the normal tissues, should improve local control and decrease potential radiation related problems to the CNS.

Analysis of Survival in a Retrospective Study of 86 Dogs with Brain Tumors
TL;DR: Both the mild and moderate groups had a more favorable prognosis compared with dogs who had severe initial neurologic impairment, and those dogs who were treated with cobalt-60 radiation, with or without other combinations of therapy, lived significantly longer than those who received surgery, or dogs who received symptomatic treatment.

TL;DR: Results of necropsy examination in ten cats revealed a large pituitary acidophil adenoma, marked left ventricular and septal hypertrophy, dilated cardiomyopathy, arthropathy affecting the shoulder, elbow, or stifle, and glomerulopathy characterized by expansion of the mesangial matrix and variable periglomerular fibrosis.

TL;DR: During the HAART era, AIDS-related primary CNS lymphoma showed a strong decline, toxoplasmic encephalitis remained stable, and progressive multifocal leukoencephalopathy showed a slight increase, and focal white matter lesions without mass effect or contrast enhancement became the most frequently seen focal brain lesion.
