Q
Cerebral abscess
A
The early stages of cerebritis and abscess formation are associated with nonspecific symptoms, including low-grade fever, headache, and lethargy.
CT with contrast and MRI are the most reliable methods of demonstrating cerebritis and abscess formation. MRI is the diagnostic test of choice.
MRI T2 weighted images indicate increased signal intensity. An abscess cavity shows a ring-enhancing lesion by contrast CT, and the MRI also demonstrates an abscess capsule with gadolinium administration.
