brain abcess Flashcards
1
Q
what are four stages of abcess formation
A
1- early cerebrit is (day 1-3) involves minimal central
necrosis and surrounding edema, with subtle radiographic
features.
2- late cerebrit is (4-9 days), with early discontinuous sparse enhancement.
3-early capsule formation (day 10-14), fibroblasts create a thin capsule that
exhibits contrast enhancement on computed tomography
4- (day 15) The late capsule stage
displays greater contrast enhancement along a thicker

Q
what are MR spect findings
A
The existence of resonance peaks for succinate,
acetate, lactate, and amino acids (such as valine and leucine)
within the central cavity suggests the presence of a brain abscess.
