• Neurosarcoidosis can mimic infection (viral, tuberculosis, or cryptococcus), toxic leukoencephalopathy & malignancies like gliomatosis cerebri or angiocentric lymphoma.

• MRI in neurosarcoidosis often reveals enhancing periventricular white matter lesions, in this case mimicking diffuse gliomatosis cerebri1,2.
