This paper describes a small intracranial aneurysm incidentally found in a 24-month-old Nova Scotia Duck Tolling Retriever evaluated for a recent history of lethargy, fever, and cervical pain. The clinicopathological analysis revealed leukocytosis, and increased haptoglobin and C-reactive protein consistent with severe flogistic process. Nonenhanced computed tomography of the brain and cervical spine showed a diffuse encephalopathy and moderate cervical syringohydromyelia. Computed tomography angiography series of the brain showed a small saccular dilation at the joining point of the two rostral cerebral arteries consistent with a small aneurysm. Cerebrospinal fluid examination led to the final diagnosis of aseptic meningitis. The dog was discharge with a long-term corticosteroid therapy for the meningitis. At two-month follow-up evaluation, the cerebrospinal fluid examination was normal and the computed tomography of the brain showed no abnormalities except for the stable aneurysm. To our knowledge, this is the first description of a spontaneous cerebral aneurysm in dogs and serves to broaden the spectrum of cerebrovascular diseases in this species.

AbstractWe report the case of a 4-year-old boy suffering from a cerebral form of toxocariasis. High serum titres of anti-Toxocara antibodies indicated that the primary infection was induced by a high number of Toxocara eggs and that the larvae did not penetrate to cerebrospinal fluid due to the hematoencephalic barrier. MRI of the patient’s brain showed multiple focal lesions spread diffusely in almost all parts of the brain, predominantly paraventricularly. These might be eosinophil-rich granulomatous infiltrates enclosing larvae. Extensive morphological changes were the cause of serious neurological symptoms, most of them being reversible after follow-up therapy. Radiology proved to be useful diagnostic method, but the specific serological assessment had a key role for the final diagnosis. In conclusion, diagnosis of this patient was intracranial primary Toxocara infection with central quadruparesis and parainfective myocarditis.

Background: Until the 70s, cerebrovascular diseases (CVDs) were neglected to the lack of resources. However, due to the advancement of technology, several imaging tests have appeared, such as magnetic resonance and computed tomography, which facilitated the diagnosis and the understanding of the pathophysiology of each disease. Objectives: The objective of this work is to identify the main CVDs signs and symptoms. Methods: An integrative literature review was carried out based on selected articles from Google Scholar, PubMed and SciELO, using the terms headache, cerebrovascular disease, neurology. Results: CVDs are characterized by causing damage to brain vessels, due to changes in blood flow momentarily or permanently in an area of the brain, allowing them to be classified as ischemic or hemorrhagic. In ischemic there is a blockage of blood flow and, consequently, of oxygen to areas of the brain, in hemorrhagic rupture of a vessel occurs and, with this, blood leakage. Therefore, it is necessary to recognize the signs and symptoms early, in order to prevent loss of neurological function, movements on one side of the body and the presence or absence of headaches in both patients, with ischemic CVD and hemorrhagic CVD prevent rapid loss of consciousness accompanied by severe headache. Such signs and symptoms associated with the patient’s family history and lifestyle can help in the diagnosis of this disease. Conclusion: Therefore, it is important to recognize the signs and symptoms of CVDs, in order to determine the treatment and advise the patient, which will guarantee a better prognosis.
