The case of a 27-year-old man with a 6-week history of headache, mental status changes, and polyradiculopathy attributable to hypoglycorrheic lymphocytic meningitis is presented. Extensive testing for occult systemic sarcoidosis was negative. The presence of noncaseating granulomatous inflammation was established by open brain biopsy, and the patient improved clinically with oral steroid therapy. In individuals with undiagnosed chronic meningitis, brain biopsy may be necessary to rule out isolated neurosarcoidosis.<\/jats:p>","DOI":"10.3171\/jns.1993.78.6.0994","type":"journal-article","created":{"date-parts":[[2009,5,27]],"date-time":"2009-05-27T14:58:28Z","timestamp":1243436308000},"page":"994-996","source":"Crossref","is-referenced-by-count":36,"title":["Biopsy-proven isolated sarcoid meningitis"],"prefix":"10.3171","volume":"78","author":[{"given":"Stephan A.","family":"Mayer","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gregory K.","family":"Yim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen T.","family":"Onesti","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Timothy","family":"Lynch","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Phyllis L.","family":"Faust","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karen","family":"Marder","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Endocrinol Metab Clin North Am","first-page":"645","article-title":"Endocrine complications of sarcoidosis.","volume":"20","author":"Bell","year":"1991"},{"key":"b2","series-title":"JAMA","first-page":"62","article-title":"Isolated CNS sarcoidosis.","volume":"245","author":"Cariski","year":"1981"},{"key":"b3","series-title":"Medicine","first-page":"261","article-title":"Neurosarcoidosis: signs, course and treatment in 35 confirmed cases.","volume":"69","author":"Chapelon","year":"1990"},{"key":"b4","series-title":"J Neurosurg","first-page":"851","article-title":"Presentation of central nervous system sarcoidosis as intracranial tumors.","volume":"63","author":"Clark","year":"1985"},{"key":"b5","series-title":"Ann Intern Med","first-page":"336","article-title":"Neurologic manifestations of sarcoidosis.
