Brain MRI. (A to D) The first MRI. Initial outside brain MRI was not remarkable, except bilateral mastoiditis and extensive sinusitis. (E to H) The second MRI. Repeated brain MRI after 5 months shows new meningeal thickening with enhancement around the tentorium cerebelli, inferior aspect of frontotemporal lobe adjacent to sinuses and nasopharynx. Also diffuse sinusitis in bilateral frontal, ethmoid, sphenoid, and maxillary sinuses were still existed.
