Three patients with cerebral cryptococcosis and concomitant neurosarcoidosis had CSF-CXCL13 levels considerably above the threshold (1380 pg/mL, 2307 pg/mL, 45,609 pg/mL), similar to in one patient with aspergillosis and CNS involvement (480 pg/mL). The gene discussed is CXCL13; the disease is aspergillosis.
