Central nervous system aspergillosis has increased dramatically in recent years. Most of the cases are immunocompromised patients infected from a primary site, usually the lungs or paranasal sinuses, and the organism may spread to the central nervous system. Different neuroimaging patterns that have been reported vary depending on the immunological status of the patients and on the age of the lesions. Description of typical radiological patterns in cerebral aspergillosis patients may be helpful in establishing early diagnosis and treatment. In this case report, we present magnetic resonance images of cerebral aspergillosis and the contribution of diffusion-weighted magnetic resonance imaging to the diagnosis.
