Transient focal neurological deficit in sarcoidosis.

Sarcoidosis presents only infrequently with stroke or focal neurological deficit and recurrent focal neurological deficit is rarer still. This case report describes a patients presenting with episodic non-fluent dysphasia of abrupt onset occurring during a period of 18 months without evidence of seizure activity or macroscopic granulomatous collection. The case illustrates that the presentation of neurosarcoidosis may mimic classic reversible ischaemic neurological deficit.
