1 Two patients with bone defects on high-resolution CT and normal results of radionuclide cisternography and CT cisternography. Two patients with bone defects on high-resolution CT and normal results of radionuclide cisternography and CT cisternography. A, Coronal CT scan shows a defect (arrow) in the right cribriform plate with adjacent mucosal thickening.B, Coronal CT scan of the temporal bone shows a large defect (arrow) in the tegmen mastoideum and mucosal thickening in the postsurgical mastoid bowl. No contrast accumulation is seen in the mastoid defect. Surgery confirmed the defect and leak in this patient. Jeffrey A. Stone et al.
