  • Title: Arachnoid granulations--computerized tomography and magnetic resonance imaging features: a case report.
    Author: Chen SS, Shao KN, Chiang JH, Chang CY, Lao CB, Lirng JF, Teng MM.
    Journal: Zhonghua Yi Xue Za Zhi (Taipei); 1999 Jan; 62(1):46-50. PubMed ID: 10063712.
    Abstract:
    A 71-year-old woman had arachnoid granulations found in the straight and transverse sinuses on computerized tomography (CT) and magnetic resonance imaging (MRI). The arachnoid granulations appeared as low-density masses on CT. They gave low signals on T1-weighted MR images and high signals on T2-weighted images. Arachnoid granulations are usually of no clinical significance. They have characteristic CT and MRI manifestations and should not be mistaken for sinus thrombosis or intrasinus tumors.
