Brain MRI. (a) Axial T2 weighted: three nodular lesions, two in right frontal lobe and one in the left occipital lobe, with hypointense central core, hyperintense peripheral margin, and vasogenic oedema. (b) Axial T1 + gadolinium: ring-enhancing lesions and absent leptomeningeal enhancement.

Brain MRI disclosed three ring-enhancing T1 and T2 hypointense cortical lesions, two located in the right frontal lobe and one in the left occipital lobe, associated with vasogenic oedema and absent leptomeningeal enhancement (Figure 1).
Histologic examination of mesenteric lesion: multiple and noncaseating granulomas with a predominantly perivascular distribution (Hematoxylin and Eosin stain, magnification x40, x100, and x200).
