Intracranial Candida parapsilosis infection occurring 2 years after burr-hole drainage for chronic subdural hematoma: a case report
Abstract
Background: Chronic subdural hematoma (CSDH) is a common condition affecting patients undergoing neurosurgical treatment for which burr-hole drainage remains the standard treatment. Postoperative fungal infections following this procedure are extremely rare, but can lead to severe consequences.
Case description: A 66-year-old male with a history of hypertension and schizophrenia underwent bilateral burr-hole drainage for bilateral frontotemporoparietal CSDH at another hospital 2 years prior to presentation. In the intervening years following this procedure, he experienced recurrent headaches, developed involuntary tongue protrusion and limb shaking, and suffered one episode of seizure 10 days before admission. Imaging suggested recurrence and possible organization of the bilateral CSDH. Bilateral craniotomy for hematoma evacuation was performed. Intraoperative examination revealed the organization and thickening of the subdural hematoma membrane, with a maximum thickness of approximately 1 cm. Postoperative pathological examination unexpectedly revealed structures suggestive of fungal hyphae. Subsequent cerebrospinal fluid culture confirmed the presence of Candida parapsilosis infection, establishing the definitive etiological diagnosis. The patient was successfully cured through surgical evacuation, antifungal therapy consisting of sequential voriconazole and fluconazole treatment, temporary lumbar drainage, and comprehensive management of complications, although the course…
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
