Neurosarcoidosis as a Cause of Longitudinally Extensive Myelitis: Neuroimaging Clues for Diagnosis

The clinical presentation of neurosarcoidosis is highly variable, and in rare instances, isolated spinal cord involvement may be the sole clinical manifestation. Extensive spinal cord involvement revealed on magnetic resonance imaging (MRI) of the spine is a key finding in spinal neurosarcoidosis. The presence of longitudinally extensive transverse myelitis, defined as lesions extending more than three vertebral segments on MRI spine, implies a wide differential diagnosis and neurosarcoidosis as a cause may be easily overlooked with grave consequences
