Contrast-enhanced CT scans show increased enhancement at the right cavernous sinus.A, Contrast-enhanced CT scan obtained in 1994 shows that the right tentorium is thickened with homogeneous enhancement due to an inflammatory reaction of the pachymeninges.B, Contrast-enhanced CT scan obtained at a more caudal level shows that involvement of the right cavernous sinus correlates with the patient’s symptom of optic neuropathy.
