Abstract:
Objective To analyze the clinical features of patients with uncommon fungal infections in central nervous system (CNS).Methods Thirty-five patients with uncommon CNS fungal infections who were admitted to Huashan Hospital from 1997 to 2010 were retrospectively reviewed.The pathogens,symptoms and signs.treatments of patients were evaluated.The data were analyzed by rank sum test and Fisher'S exact test.Results Twenty-nine of the 35 patients met the definition criteria of prover CNS fungal infections,while the other 6 had probable diagnosis.Predisposing factors were found in 86% of all patients.The most common pathogens were Aspergillus and Candida species.The symptoms and signs commonly occurred including fever(22 cases),headache(19 cases), cranial neuropathy(12 cases),and meningeal irritation sign(12 cases).High white blood cell count,high protein level,and low glucose level were the main findings of cerebrospinal fluid (CSF) analysis.Patients with cerebral aspergillosis were more frequently accompanied with immunocompromised conditions, and they often got CNS aspergillosis from hematogenous dissemination or direct extension of paranasal sinus infection.Cerebral granuloma and abscess were the common clinical characteristics of CNS aspergillosis.Cerebral candidiasis often arose from neurosurgical surgery or traumatic brain injury,and these patients were usually presented with meningitis.All patients were treated with antifungal drugs and (or) surgical intervention and 77%(27/35) of the patients achieved complete or partial responses. Antifungal agents combined with surgical resection might improve outcome of patients with CNS aspergillosis; while removal or replacement of drainage tubes in combination with antifungal treatment showed satisfactory efficacy in patients with cerebral candidiasis who usually had shunt manipulation. Conclusions The incidence of CNS fungal infection, such as cerebral aspergillosis and candidiasis, is increasing. Early diagnose and therapeutic intervention are crucial for improving outcome.
