Abstract
Longitudinally-extensive T2-hyperintense spinal cord lesions (≥3 vertebral segments) are associated with neuromyelitis optical spectrum disorder but occur with other disorders including spinal cord sarcoidosis. When linear dorsal subpial enhancement is accompanied by central cord/canal enhancement the axial post-gadolinium sequences may reveal a “trident” pattern that has previously been shown to be strongly suggestive of spinal cord sarcoidosis. We report a case in which the patient was initially diagnosed with neuromyelitis optical spectrum disorder, but where the “trident” sign ultimately led to the correct diagnosis of spinal cord sarcoidosis.
