The authors present the case of a 78-year-old woman who developed righ
t lower-extremity paralysis after a focal seizure. Neuroradiological s
tudies revealed a small parasagittal meningioma, which at the time of
resection was found to contain a bacterial intratumoral abscess second
ary to Proteus mirabilis. This is only the second reported case of int
ratumoral abscess formation in a meningioma and the first such occurre
nce to be reported in an otherwise healthy, immunocompetent individual
.
