Figure. Brain magnetic resonance imaging findings in a 36-year-old immunocompetent man before (A, B, C) and after (D) treatment for cerebral syphilitic gumma, Saitama, Japan. A) Gadolinium-enhanced T1-weighted coronal image shows an enhanced nodular lesion in the left temporal lobe. B) Axial gadolinium-enhanced T1-weighted image shows enhancement within the cisternal segment of both the vestibulocochlear nerve complex and the facial nerve. C) Axial fluid-attenuated inversion recovery images show a hyperintense lesion-like mass in the left temporal lobe. D) Axial fluid-attenuated inversion recovery image shows complete resolution after discontinuation of treatment.
