Learning objectives: To review the most common Magnetic Resonance Imaging (MRI) features of neurosarcoidosis.
Background: Sarcoidosis is an inflammatory multisystem disorder of unknown aetiology characterised by the presence of non-caseating granulomas in tissues. Practically, no organ is immune to sarcoidosis but it most commonly affects the lungs and lymph nodes. When sarcoidosis affects the brain it is termed neuros[...]
Findings and procedure details: Leptomeningeal involvement Leptomeningeal involvement occurs with predilection for the basilar cisterns in about 40% of patients with neurosarcoidosis. Gadolinium enhancement can be diffuse or nodular on post-contrast T1 weighted MRI (Fig. 1). H[...]
Conclusion: Neurosarcoidosis has a wide spectrum of imaging features that mimic both benign and malignant conditions. MRI is highly sensitive for detecting neurosarcoidosis, but is not specific. This pictorial review has highlighted salient features which should raise the suspicion of a potential diagnosis of n[...]
