Can a planum sphenoidale be a meningioma?

Can a planum sphenoidale be a meningioma?

Morphology and signal characteristics of the mass lesion arising from planum sphenoidale are consistent with a sprasellar meningioma, which was proved after surgical resection. the identification of normal pituitary gland separate from the mass excludes pituitary origin.

Is there a hyperdense midline mass in Planum sphenoidale?

Planum Sphenoidale Meningioma. Unenhanced axial CT of the base of the skull shows a hyperdense midline mass (white arrows) arising from the planum sphenoidale region. Meningiomas of the Tuberculum Sellae and Planum Sphenoidale: A Review of 83 Cases. JE Finn, LA Moun.

What kind of MRI is used for meningioma?

On MRI, the meningioma appears hypo to isointense on T1-weighted imaging and possesses variable signal intensity on T2-weighted images. Gadolinium MR imaging demonstrates intense homogeneous or heterogeneous-enhancement of the tumor, with well-circumscribed margins.

What are the chances of developing a meningioma?

Patients with neurofibromatosis type 2 (NF-2) have a 50% chance of developing one or more meningiomas On unenhanced studies. They are isodense to slightly hyperdense

Is there a surgical technique for Planum sphenoidale?

Background: The resection of planum sphenoidale and tuberculum sellae meningiomas is challenging. A universally accepted classification system predicting surgical risk and outcome is still lacking. Objectives: We report a modern surgical technique specific for planum sphenoidale and tuberculum sellae meningiomas with associated outcome.

Is the planum part of the sphenoid bone?

The planum sphenoidale is a common term for the anterior horizontal part of the superior surface of the body of the sphenoid bone. It is known in the Terminologia Anatomica (2019) as the jugum sphenoideum or sphenoidal yoke 1. It forms part of the anterior skull base, separating the anterior cranial fossa from the sphenoid sinuses.
