Diagnostic role of Mantoux test site biopsy in neurosarcoidosis

Abstract

We discuss a patient with sarcoidosis presenting with cranial neuropathy and a cerebral mass lesion evident on imaging. Also, we review from the literature six patients with sarcoidosis presenting with cerebral mass lesion. We emphasize the diagnostic role of Mantoux test site biopsy in patients with dominant or isolated neurologic presentation because the involved sites are not easily accessible and Kveim's test antigen is not commercially available.
