Spinal neurosarcoidosis mimicking an idiopathic inflammatory demyelinating syndrome.
BACKGROUND
Intramedullary neurosarcoidosis may be the first and only manifestation of the disease and may mimic an idiopathic inflammatory demyelinating syndrome both clinically and on neuroimaging results.


RESULTS
Two patients who were seen initially with a relapsing-remitting neurologic course and a cervical intramedullary lesion on magnetic resonance imaging findings are reported. Both proved to have neurosarcoidosis. A computed axial tomographic scan of the chest showed hilar adenopathy, which provided a clue to the diagnosis.


CONCLUSIONS
Symptoms due to an intramedullary cervical lesion can be the first manifestation of neurosarcoidosis. The clinical course can mimic a demyelinating illness. A high index of suspicion and a search for sarcoidosis at extraneural sites are required for an early diagnosis. Steroid treatment is associated with a favorable outcome.
