View larger version (109K): [in a new window]   FIG 1. CT scan of the brain obtained on day 29, after the IV administration of contrast medium, shows multiple enhancing ring-shaped lesions, consistent with abscesses in both hemispheres, with marked peripheral hypoattenuation, consistent with edema.

View larger version (73K): [in a new window]   FIG 2. CT scans of the brain obtained on postoperative day 8. A, CT scan shows subarachnoid and intraventricular hemorrhage, associated with hydrocephalus. New, irregularly roundish lesions surrounded by the hyperattenuated blood can be seen inside the interpeduncular cistern. B, Contrast-enhanced CT scans show intense enhancement of these lesions, confirming the hypothesis of aneurysms of the basilar and right posterior cerebral arteries.
