In spite of significant advancements in imaging technology, monitoring, and microsurgical techniques, complete and safe removal of tentorial meningiomas remains a challenge for most neurosurgeons. Classifications of tentorial meningiomas are revised. The combined supra/infratentorial approach to resect tentorial meningioma is discussed. This approach provides a wider exposure of the supra/infratentorial region with less brain retraction. With this approach the occipital lobe and the cerebellum are exposed along the tentorium. Two illustrative cases are presented. The patients were studied with computerized tomography, magnetic resonance and angiography. The anatomy of the transverse sinus and the confluence of the sinus could be appreciated with these studies. The operative technique is described stepwise. Emphasis is placed on pre-operative evaluation and surgical technique, leading to a total surgical removal of the lesion with margins of safety. The goal of surgical treatment of tentorial meningiomas is their complete and safe removal. With this unique approach we sought to confirm that it offers a safe means of resection not only the neoplasm but also the infiltrated dura.

INTRODUCTION: Craniopharyngiomas (CF) are benign tumors, which can be cured by total resection; however, this is not always possible to achieve, thus leading to tumor recurrence. When these tumors achieve disproportionate growth, the treatment is even more difficult, fortunately grotesque CF are not frequent, making experience and data collection more arduous to obtain. CASE REPORTS: Four patients are presented here to illustrate the need for the use of a new term, "monstrous craniopharyngioma," which is proposed with the aim of making the evaluation of the different kinds of treatment available more accurate. CONCLUSIONS: Craniopharyngiomas that have grown into more than one cranial fossa with mixed solid and cystic components pose a special challenge for resection, and therefore a systematic classification and approach are required in order to obtain the best surgical results.
