MRI brain examination of a 48-year-old male with meningoencephalitis, vasculitis, and extradural fluid collection. Axial DWI (A) and ADC (B) images show acute left thalamic (white arrow) and tiny right basal ganglia lacunar infarcts secondary to vasculitis. Axial FLAIR image (C) shows a cortical high signal in bilateral higher parietal lobes suggestive of epidural collection and underlying cerebritis (star). Axial T2-weighted image (D) shows a hyperintense signal in the left thalamus and basal ganglia secondary to vasculitis.

MRI brain examination of a 48-year-old male with meningoencephalitis, vasculitis, and extradural fluid collection. Postcontrast MRI axial T1 (A), GRE sagittal (B), GRE axial (C), and GRE coronal (D) images show diffuse leptomeningeal enhancement, enhancing basal exudates and high biparietal epidural fluid collection (white arrow) with cerebritis.

Follow-up MRI brain examination after one month. Axial T2 (A), DWI (B), FLAIR (C), and postcontrast T1-weighted (D) images show significant interval improved leptomeningeal enhancement, resolution of epidural collection (not shown), and interval new communicating hydrocephalus.

Repeat MRI brain (Figure 3) showed significant improvement in leptomeningeal enhancement and resolution of epidural collection; however, there was a new communicating hydrocephalus.
