Fungal mycotic aneurysm in a patient with

backgroundCentral nervous system involvement due to aspergillosis is an extremely serious entity, particularly in patients with severe neutropenia, hematological diseases, or post-transplant cases. Immunocompetent patients can be infected by intense exposure, particularly iatrogenic after invasive procedures. CASE DESCRIPTION: We present the case of a 26-year-old male with a 1 year appendectomy background, which required epidural anesthesia. After that surgery, insidious headache presented, requiring mild analgesics for adequate control. In the following weeks, headaches increased and tomographic imaging revealed hydrocephalus. A ventriculoperitoneal shunt was placed, and empirical treatment for neurocysticercosis was established, but diagnosis was never confirmed. Sequentially, shunt dysfunction occurred twice, for which shunt replacement was performed. Cerebrospinal fluid and shunt's catheter were cultured. Some days later, a filamentous fungus was isolated and finally identified as

conclusionCerebral aspergillosis is a serious disease with high mortality in patients, particularly those without identifiable risk factors. The iatrogenic forms are serious, due to the delay of clinical diagnosis. It is important to have a high index of suspicion in patients with a history of invasive procedures such as epidural anesthesia or surgery, and who develop a persistent chronic headache or chronic meningitis.
