A 34-year-old woman presented with a 3-month history of right-sided headaches associated with photophobia and pulsatile tinnitus. Investigations including lumbar puncture revealed elevated opening CSF pressure, increased protein, and presence of monocytosis consistent with an inflammatory/infective process. Brain MRI showed an area of thickened enhancing dura around the venous sinus posteriorly. Ga scintigraphy demonstrated focal intracranial uptake in the posterior occipital region, and biopsy confirmed a chronic inflammatory infiltrate with no granulomas.
