Microsurgical approaches are the procedures of choice for high-risk patients with lesions requiring surgical treatment. The use of a microscope reduces the extent of the surgical invasion, thus minimizing the handling of healthy tissues. The authors present a surgical approach described for the first time in 1981, which has been used for the past 17 years in more than 260 patients with different tumors and vascular lesions of the anterior cranial fossa. The modification set forth in this article makes better exposure possible, allows more space for instrument handling, and improves cosmetic results. This particular report was based on the treatment of 41 patients who were observed for longer than 3 months. All of the patients were satisfied with the cosmetic result.

Sixteen patients were identified. Mean age of presentation was 8.8. An increased frequency of complications was observed in younger patients and longer survival rates in patients with greater resections; main mode of presentation was directly related to intracranial hypertension; size of tumor was not related to evolution or outcome. Modern histological classifications especially designed for children are deemed necessary to accurately diagnose GBM.

The precise and diligent evaluation of a lesion caused by an animal bite may prevent further life-endangering complications. To the best of our knowledge, there are no reports about cerebellar abscess caused by a dog bite. When cranial lesions are penetrating, an abscess must to be considered. We insist on the importance of medical evaluation and adequate treatment of such lesions.
