Abstract

Cerebral syphilitic gummas are rare entities, consisting of masses of granulation tissue that result from an exacerbated cell-mediated inflammatory response to Treponema pallidum, usually arising from the meninges of the convexity. Conventional magnetic resonance imaging and computed tomography findings of cerebral gummas have been reported, but diffusion-weighted imaging findings have not been previously described. In our patient, magnetic resonance imaging revealed a juxtacortical lesion with nodular enhancement, moderately restricted diffusion, a dural tail, and surrounding vasogenic edema. The role of diffusion-weighted imaging findings in the diagnosis of this condition is underscored.
