Abstract:
:Cranial computed tomography (CT) scans were analyzed in five patients with autopsy documented intracranial aspergillosis. All infections occurred in immunocompromised hosts. Our findings included subtle low attenuation abnormalities, minimal mass effect, and poor contrast enhancement without ring configuration, in the clinical setting of lethargy, fever, and pulmonary infection. The benign CT picture did not clearly depict the aggressive intracranial parenchymal destruction.
