Cryptococcal intracerebral mass lesions: the role of computed tomography and nonsurgical management.

Cephalic computed tomography (CT) is a sensitive technique for defining certain intracerebral diseases. Four patients with cryptococcosis were evaluated with cephalic computed tomography over 3 years. All had focal, intracerebral "contrast-enhanced" lesions consistent with cryptococcal mass lesions, confirmed histopathologically in two. An analysis of 55 cases of cryptococcal intracerebral mass lesions from the literature showed that 18% of patients with these lesions associated with cryptococcal meningitis did not have specific symptoms or signs of focal intracerebral disease or increased intracranial pressure. We therefore recommend that patients with cryptococcal meningitis, regardless of localizing symptoms or signs, be considered for cephalic CT evaluation to ascertain the presence of mass lesions. Three patients in this report were treated with systemic antifungal medication without surgery. Decreased size or disappearance of these lesions was seen on sequential CT scan in all patients. We conclude that selected patients with cryptococcal intracerebral mass lesions may be managed successfully with systemic antifungal therapy alone.
