Article Figures & Data
Figures
- fig 1.
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.
- fig 2.
Patient with a defect revealed by CT and a leak revealed by radionuclide cisternography but not by CT cisternography.
A, Radionuclide cisternogram of the head, anterior planar view, shows an abnormal accumulation of radionuclide (arrow) in the left mastoid region.
B, Coronal CT scan of the temporal bone shows a defect (arrow) in the tegmen tympani with adjacent mucosal thickening. The bone and dural defect were confirmed at surgery.
- fig 3.
Patient with a bone defect revealed by CT and a leak evident by CT cisternography but not by radionuclide cisternography.
A, Coronal CT scan of the face shows a large defect (straight arrow) in the right cribriform plate with adjacent mucosal thickening. Nasal pledgets can be seen within the nasal cavity (curved arrow).
B, Coronal CT cisternogram of the same region shows accumulation of contrast medium at the defect and extending into the ethmoidal sinus (arrow). The results of radionuclide cisternography and nasal pledgets were normal. There was no surgical confirmation.
- fig 4.
Patient with a bone defect revealed by CT and positive results of radionuclide cisternography and CT cisternography.
A, Coronal CT scan of the face shows a defect (arrow) of the lateral sphenoidal sinus roof with mucosal thickening filling the sphenoidal sinus.
B, Coronal contrast-enhanced CT cisternogram shows contrast medium extending through the defect (arrow) and within the right sphenoidal sinus (curved arrow). The nasal pledgets indicated a leak in the region of the right sphenoethmoidal recess, although the cisternogram did not show abnormal accumulation of the radionuclide. The defect and CSF leak were confirmed at surgery.
