Proven pulmonary cryptococcosis due to capsule-deficient Cryptococcus neoformans does not differ clinically from proven pulmonary cryptococcosis due to capsule-intact Cr. neoformans.

We compared the clinical manifestations, laboratory and radiologic findings, and outcomes of eight patients with proven pulmonary cryptococcosis (PC) caused by capsule-deficient Cryptococcus neoformans with those of six patients with PC caused by capsule-intact Cr. neoformans. The presentations and outcomes did not differ significantly between the groups.
