What CT findings indicate severe cerebral edema?

Midline shift >5mm, loss of basal cisterns, sulcal effacement, and bilateral hemispheric involvement indicate severe edema. The Marshall CT classification quantifies these findings systematically for research and clinical use.

When is decompressive craniectomy indicated for cerebral edema?

DESTINY II and HAMLET trials support decompressive hemicraniectomy for malignant MCA infarction within 48h of onset in patients <60 years, reducing mortality and improving functional outcomes despite higher rates of severe disability.
