Imaging of neurosarcoidosis: common, uncommon, and rare.
Sarcoidosis is an idiopathic inflammatory disease that may affect any organ system and have protean manifestations. Neurosarcoidosis refers to involvement of the central nervous system and may occur in patients with known sarcoidosis, or be the initial manifestation of the disease. In the latter, it can be a source of considerable confusion, given the non-specific imaging appearance. The aim of this review is to describe the imaging spectrum of neurosarcoidosis, including follow-up imaging and superimposed infections, which may occur secondary to immunosuppression. An increased awareness of this great mimicker could potentially expedite diagnosis and reduce morbidity.
