Tentorium Meningioma: Located near where the brain connects to the brainstem, an area known as the tentorium cerebelli. Diagnosis: Tentorial Mengioma Findings: Rounded enhancing mass located in the infratentorial region as demonstrated on above MR with contrast scans. Relatively homogeneously enhancing lesion is identified with moderate mass effect. Key Points: Tentorial meningiomas are relatively uncommon lesions located along the tentorium, adjacent to the cerebellum. These types of lesions that are Posterior fossa meningiomas include tentorial, clival, cerebellopontine angle and foramen magnum meningiomas.

These types of posterior fossa meningiomas can cause headaches, seizures, and difficulty walking. Purpose: Tentorial meningiomas, comprising approximately 3-6% of all intracranial meningiomas, are complex entities with an intricate relationship to surrounding structures and require multiple surgical approaches. In the present study, the rationale for deciding the approaches for TMs and the perioperative management dilemmas were evaluated. TENTORIAL MENINGIOMAS* By MANNIE M.

This paper discusses about various operative approaches and their overall surgical outcome. Twenty-five meningiomas located at the tentorial notch were surgically treated between 1978 and 1993 at the Neurosurgical Department of Nordstadt Hospital in Hannover, Germany. Nineteen meningiomas were classified as originating from the lateral tentorial incisura (Group I) and six were from the posteromedial tentorial incisura (Group II).
