CT
Toxoplasmic encephalitis is the most common cause of intracerebral mass lesions and is thought to be caused by reactivation of chronic infection. Typically cerebral toxoplasmosis manifest as multiple lesions, with a predilection for the basal ganglia, thalami, and corticomedullary junction. Intracerebral mass lesions can be diagnosed using CT scan. Findings of CT brain include:
- Multiple hypodense regions predominantly in the basal ganglia and at the corticomedullary junction.
- Size is variable, from less than 1 cm to more than 3 cm, and there may be associated mass effect.
- Enhancement: following administration of contrast there is nodular or ring enhancement which is typically thin and smooth 5
- Double-dose delayed scan: may show a central filling on delayed scans
- Calcification: seen in treated cases; may be dot-like or thick and 'chunky'
