Delay in the diagnosis of meningiomas of the tuberculum sellae meningioma and planum sphenoidale meningioma is detrimental to the patient in terms of visual recovery, morbidity and mortality. Early accurate diagnosis of these tumors is possible through the use of neuroimaging which is recommended for all patients with unexplained impairment of vision ¹⁾.

Neuroimaging characteristics on CT include a homogenously and avidly contrast-enhancing, extra-axial mass, with a well-defined border and broad dural attachment and/or dural tail. The tumor is associated with moderate circumferential edema and mass effect. There may be an area of central calcification within the tumour and hyperostosis of adjacent bony structures may be evident.
