  • Title: [Computed tomography in the diagnosis of intracranial meningiomas].
    Author: Vavilov SB, Shmyrev VI, Levina GIa, Sozykin VA.

    Abstract:
    CT scans in 91 patients revealed the increased density ovoid or circular structures with sharply defined borders to be most characteristic of the intracranial meningiomas. However, these often had densities very low or indistinguishable against the background of the surrounding tissues' absorption coefficients. Irrespective of the initial tumor density CT will reveal the contrast media accumulating in it, diffuse as a rule. Perifocal edema is also typical of the meningiomas, manifested by the early detected shifts and compression fo different brain structures. CT and pathological data compared, the structural features of the meningiomas were identified which determine their density, borders and contrasting media accumulation.
