Meningiomas are extra-axial tumors and represent the most common tumor of the meninges.They are a non-glial neoplasm that originates from the meningocytes or arachnoid cap cells of the meninges and are located anywhere that meninges are found, and in some places where only rest cells are presumed to be located. Although they are usually easily diagnosed and are typically benign with a low rate

Mar 2, 2017 Introduction: Tentorial meningiomas are notorious for their critical location. Selection of a suitable approach that exposes the

These meningiomas are dichotomized into falcotentorial and torcular. Torcular meningioma are stated to be located in the posterior cranial fossa attached to the confluence of sinuses with or without sinus invasion. • Meningiomas of the posterior cranial fossa is about 9% of all intracranial meningiomas • Tentorial meningiomas is about 30% of the posterior fossa meningiomas • First described by Andral in 1833 • Reviewing the deep venous system and venous drainage of the temporal lobe is the cardinal step when planning for the subtemporal and petrosal approach. ¶ Objective. Report our experience with 27 tentorial meningiomas (TM) surgically treated between 1985 and 1998. Methods. The records of 27 patients with TMs were retrospectively reviewed for clinical presentation, neuroradiological evaluation, surgical treatment and long-term outcome.

Additional images The Challenge: Tentorial Meningioma Nickkie’s tumor was a tentorial meningioma, a rare, benign tumor found along the surface of the tentorium cerebelli in the brain. Because of where the tumor was located, Dr. Friedlander recommended that Nickkie have it removed at UPMC since he and his team had expertly handled such cases before. Posterior fossa meningiomas include tentorial, clival, cerebellopontine angle and foramen magnum meningiomas. Tentorial meningiomas are those located under the surface of the tentorium cerebelli. Clival meningiomas proceed from the clivus bone in the direction of the middle cranial fossa or the direction of the brainstem. In this group, the falco-tentorial meningiomas are considered to be the rarest. CASE REPORT: The paper presents three cases of the tentorial and falco-tentorial junction meningiomas.

Medial tentorial meningiomas protrude along the tentorial incisura into the posterior fossa and compress the posterior brainstem and surrounding neurovascular structures. A tentorial incision along the red line will place the trochlear nerve at risk of injury and should be avoided. The black line defines the route of correct tentorial incision (a).

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.

66-year-old female underwent a left suboccipital craniotomy for resection of a tentorial meningioma. The postoperative course has been difficult, marked by deterioration associated with posterior temporal and cerebellar edema and hemorrhage. First she seems to be in good general conditions showing only a slight strength deficiency in the left upper 2018-02-01 · Tentorial meningiomas comprise 3%–6% of all intracranial meningiomas. 1, 2 Because of their critical relation to the neurovascular structures around the tentorial hiatus, microsurgical resection is challenging. Tentorial herniation is a serious symptom, especially since the brainstem is likely to be compressed as well if the intracranial pressure rises further.

7 public playlist includes this case Meningiomas are the most common benign intracranial tumor. They originate from arachnoid cap cells, which are cells within the thin, spider web-like membrane that covers the brain and spinal cord. The arachnoid is one of three protective layers, collectively known as the meninges, which surround the brain and the spinal cord. Tentorial meningiomas represent about 5% of intracranial meningiomas. Tentorial meningiomas are rare tumors located along the surface of the tentorium cerebella in the brain.
