Presentation transcript:

Patient 6, a 35-year-old man presenting with headache and bilateral deficits of CN III, VI, VII, X, and XII. The patient had been previously treated with steroids and oral antibiotics for paranasal sinus inflammatory disease. Patient 6, a 35-year-old man presenting with headache and bilateral deficits of CN III, VI, VII, X, and XII. The patient had been previously treated with steroids and oral antibiotics for paranasal sinus inflammatory disease. A, Sagittal T1-weighted MR image (600/11/2) shows diffuse low signal intensity in the clivus, with prominence of preclival soft tissue and thickening of the retroclival dura. B, Axial T2-weighted spin-echo image (2500/80/0.75) demonstrates mild circumferential mucosal thickening in the sphenoid sinus. Abnormal low signal intensity soft tissue is present within the cavernous sinuses bilaterally, and there is mild narrowing of the left cavernous carotid flow void. High signal intensity in the left temporal lobe (arrowheads) is present, presumably due to either focal cerebritis or localized venous ischemia/infarction. C, Axial T1-weighted spin-echo image (600/11/2) demonstrates abnormal soft tissue in the cavernous sinuses bilaterally and swelling of the left temporal lobe with poor definition of adjacent cerebral sulci. The left internal carotid artery appears patent but narrowed. Fat within the orbits and sphenotemporal buttresses is unremarkable. D, Contrast-enhanced axial T1-weighted image (600/11/2) with fat saturation demonstrates dural and leptomeningeal enhancement along the anterior left temporal lobe, as well as expansion of the cavernous sinuses bilaterally and extension of abnormal enhancement along the tentorium. Apparent enhancement of the left orbital fat is secondary to a failure of fat saturation in the inferior orbit of this somewhat rotated patient. Note that the orbital fat is seen to be normal in panel C. Patrick C. Chang et al. AJNR Am J Neuroradiol 2003;24:1310-1316 ©2003 by American Society of Neuroradiology
