====== Toxoplasma abscess ======

CT/MRI findings in toxoplasma abscess


1. most common findings: large area (low density on CT) with mild to moderate edema, ring enhancement with IV contrast in 68% compatible with abscess (of those that did not ring-enhance, many showed hypodense areas with less mass effect, with slight enhancement adjacent to the lesion), well-circumscribed margins

2. most commonly located in [[basal ganglia]] are also often subcortical

3. often multiple (typically > 5 lesions) and bilateral

4. usually with little to moderate mass effect (in BG, may compress [[third ventricle]] and Sylvian
aqueduct, causing obstructive hydrocephalus)

5. most patients with toxoplasmosis had evidence of cerebral atrophy
