 AB    PURPOSE: To determine the predictive imaging (CT and/or MR) features of
       brain toxoplasmosis recurrences in acquired immunodeficiency syndrome.
       METHODS: The imaging studies of patients with brain toxoplasmosis were
       retrospectively reviewed. Forty-three patients with significant decrease
       or disappearance of brain lesions under specific treatment on follow-up
       imaging examinations were included. MR examinations were performed using
       T2- and T1-weighted sequences, before and after intravenous
       administration of gadolinium-DOTA. RESULTS: A recurrence occurred in 11
       (26%) of 43 cases. Ten (91%) of these 11 patients with recurrence showed
       focal persistent enhancement after the initial treatment of
       toxoplasmosis abscess. One of the 11 patients with recurrence showed no
       persistent enhancement; 3 patients showed persistent enhancement but had
       no recurrence. CONCLUSIONS: Recurrences of brain toxoplasmosis in our
       series correlated with persistent contrast enhancement. We hypothesize
       that demonstration of persistent areas of contrast enhancement after
       treatment for initial toxoplasmosis may be a valuable sign for
       identifying patients at risk for recurrence.
