Stereotactic biopsy of a brain lesion caused by .

Background: Invasive fungal infections are an increasing problem in immunosuppressed patients. In patients with the central nervous system involvement, there is a high case fatality rate. There is a very limited experience with infections caused by (HA) in such cases and most often diagnosis is only confirmed postmortem.

Case Description: We report the case of a 53-year-old woman with acute myeloid leukemia. After primary therapy with daunorubicin, cytarabine, and gemtuzumab ozogamicin, the patient developed pneumonia and later neurological symptoms caused by multiple gadolinium-enhancing brain lesions in magnetic resonance imaging (MRI). Stereotactic biopsy of a frontal precentral lesion was performed and revealed HA infection. The patient died in the further course secondary to cardiopulmonary problems.

Conclusion: Stereotactic biopsy is a safe way to establish the diagnosis of unclear lesions such as HA infection. We recommend to perform stereotactic biopsy early in immunocompromised patients with brain lesions to guide further treatment.
