Abstract

Magnetic resonance (MR) has become the most important imaging method in the diagnosis of intracranial meningeomas. The aim of this study was to present the characteristics of meningiomas. Thirty patients with histologically proven intracranial meningiomas were studied. There were 20 female and 10 male patients (median=53±15 years). All MR examinations were performed on the MR apparatus, the strength of which is 1.5T. All patients were scanned with T1, T2-weighted imaging (T1WI, T2WI), FLAIR and contrast-enhanced T1WI. Most of the tumors showed on T1WI the isointense signal (80%) and hypointense signals (20%). On T2WI, most of tumors showed isointense signal (80%) and hyperintense signal (20%). On FLAIR, the majority of tumors showed isointense signal (80%) and hyperintense signal (20%). After contrast administration, significantly intensive sign in contrast-enhanced T1WI was observed in 90% of the tumors, while 10% showed moderate enhancement. Supratentorial lesions were found in 83,34% of cases and infratentorial lesion were demonstrated in 16,66% of cases. MRI characteristics of intracranial meningiomas are various. Intracranial meningiomas usually show isointense and hypointense signals on T1WI; isointense and hyperintense ones on T2WI; isointense and hyperintense ones on FLAIR images, with intense enhancement after contrast administration. The most common is supratentorial localisation.
