CSF rhinorrhea following head trauma in a 42-year-old woman. Coronal T1-weighted MR cisternogram obtained after intrathecal administration of gadopentetate dimeglumine (Gd-DTPA) shows contrast leakage (arrow) extending from the cranial subarachnoid space into the ethmoid air cell region from a defect in the right side of the cribriform plate.

CSF rhinorrhea in a 39-year-old man after sellar region surgery. A, Coronal thin-section CT scan reveals a defect in the right side of the sphenoid sinus (arrow) and opacification of the right sphenoid sinus. B and C, Coronal and axial T1-weighted fat-saturated MR cisternograms obtained after the intrathecal administration of Gd-DTPA show contrast leakage (arrows) extending from the cranial subarachnoid space into the right sphenoid sinus.

CSF rhinorrhea and otorrhea following head trauma in a 15-year-old adolescent boy. A, Axial thin-section CT scan shows a defect in the left petrous temporal bone (arrow) and opacification of the left middle ear cavity. B and C, Coronal and axial T1-weighted fat-saturated MR cisternograms show contrast leakage in the middle ear cavity and eustachian tube (arrows).

CSF rhinorrhea following head trauma in a 32-year-old woman. A–C, Axial, coronal, and left parasagittal T1-weighted fat-saturated MR cisternograms obtained after the intrathecal administration of Gd-DTPA show contrast leakage (arrows) extending from the cranial subarachnoid space into the left infratemporal fossa.

CSF rhinorrhea following head trauma in a 35-year-old man. A, Coronal thin-section CT scan reveals a defect in the roof of the sphenoid sinus (arrow) and opacification of the right sphenoid sinus. B, A coronal T1-weighted fat-saturated MR cisternogram obtained after the intrathecal administration of Gd-DTPA shows contrast leakage (arrow) extending from the cranial subarachnoid space into the right sphenoid sinus. C, After repair of the dural rupture, suspected CSF rhinorrhea recurred 1 week later and the patient underwent control MR cisternography. Images obtained in the first hour show probable leakage (arrow). D and E, Leakage becomes obvious in late images taken in the third and fifth hours (arrows).
