1 Sagittal enhanced 3D TOF image through the right side of the Meckel cave in a 53-year-old-man.
Sagittal enhanced 3D TOF image through the right side of the Meckel cave in a 53-year-old-man. Enhancing ganglion (thick white arrow) is shown at the anteroinferior margin of the cave, in continuity with the dural wall (white arrowhead). Superior and inferior lips of the ganglion (thin white arrows) are well depicted. No sensory rootlets are seen in the trigeminal cistern (TC). Ophthalmic nerve (V1) and maxillary nerve (V2) are hypointense, linear structures surrounded by strongly enhancing venous channels (black arrowheads) in the lateral wall and along the inferior border, respectively, of the cavernous sinus. V2 enters the foramen rotundum (FR), while V1 passes to the superior orbital fissure (SOF). CA = carotid artery, PC = prepontine cistern, TE = cerebellar tentorium, TL = temporal lobe.
