Patient:
40 Years, female
Clinical History:
- A 40 year-old female presented with
- H/O SUDDEN ONSET UNCONSCIOUSNESS
- H/O FEVER /VOMITING
- H/O GENERAL BODY PAIN/WEAKNESS
- NO H/O TRAUMA /FALL
Imaging Findings:
Plain and contrast MRI Brain was advised which showed Bilateral Symmetrical areas of cortical thickening with edema in bilateral medial temporal lobes, limbic cortex and hippocampus. It appears as hypo-intense signal on T1 WI , hyper-intense signal on T2 and T2 FLAIR images. It shows and restricted diffusion with corresponding low ADC values. No obvious enhancement noted post contrast. (Fig. 1, 2, 3, 4 and 5- red arrow).
