CASE 55: MRI BRAIN

10M fever and headache

Findings reveal enhancing cortical exudates in the right perimesencphalic cistern and the Sylvian fissure. These findings are visible on Contrast study - FLAIR sequences predominantly compared to standard T1+ C sequence.

Diagnosis

Pyogenic Meningitis

RAD PEARLS

Gd-DTPA-enhanced MR images are superior to postcontrast CT scans

Contrast enhanced FLAIR sequences are superior to standard T1 Contrast sequences for meningitis

Reason?:it is possible that difference in the CSF protein concentration could have made FLAIR more sensitive
