ObjectiveCoccidioidomycosis is a fungal infection endemic to the southwestern United States. Hydrocephalus can develop after intracranial dissemination, and management of this disease entity is difficult. We present our institutional experience with shunting coccidioidomycosis-related hydrocephalus.MethodsA cohort of patients with coccidioidomycosis-related hydrocephalus undergoing an intracranial shunt placement were retrospectively identified over a 24-year period. Demographics and treatment characteristics were obtained from the electronic medical record.ResultsThirty patients undergoing 83 procedures were identified, with a median follow-up of 19.4 months. The average age of the cohort was 43 years at the time of initial shunt placement. Most patients (66.7%) had ≥1 shunt failure, and the average number of revisions required was 2.6 for patients who had shunt failure. The average shunt valve pressure threshold required was 5.5 cm H2O, and patients who harbored the disease for a longer period (>7 months) had a lower pressure setting for initial shunt valves. Shunts without an antisiphon component were more likely to be failure free on multivariate analysis (odds ratio, 9.2; 95% confidence interval, 2.4-35.7). Death was associated with a longer diagnosis-to-shunt time interval, and patients having been diagnosed with intracranial disease for more than 10 months before shunt placement had significantly higher rates of death on follow-up.ConclusionsPatients with coccidioidomycosis-related hydrocephalus typically have normal to low pressure setting requirements, high shunt failure rates, prolonged hospitalizations, and mortality. In this disease context, shunt valves without an antisiphon component are associated with lower shunt failure rates.Copyright © 2020 Elsevier Inc. All rights reserved.
