The lesions were spread throught both hemispheres - one in the right frontal lobe, one in the right parietal lobe, four in the left parietal lobe and one in the left occipital lobe (Figure 1A). Magnetic resonance imaging (MRI) confirmed the presence of multiple lesions which were surrounded by edema and contained hemosiderin deposits (Figure 1B).
(A, B) The MRI (axial FLAIR images) one month follow-up.

MRI revealed multiple lesions very similar to those reported in November 2011 (Figure 2A, 2B).
Brain MRI (axial T2-weighted image) from May 2012. The post-surgical changes in the right frontal lobe and partial resolution of lesion in the left parietal lobe.

As previously, central contrast enhancement and edema were noted (Figure 3).

The computed tomography of the chest aroused a suspicion of an abnormal mass in the left atrium (Figure 4).
Brain MRI (axial T2-weighted image) from January 2013 with no signs of regression.

MRI of the brain revealed lesions comparable to those already described (Figure 5).
MRI from July 2013 showed partial resolution of edema (A, B, axial FLAIR images) and preserved central contrast enhancement (pre (C) and post contrast (D) axial T1 weighted images).

Partial resolution of edema surrounding brain lesions was seen on follow-up MRI in July 2013 (Figure 6A, 6B). However, central contrast enhancement was still present (Figure 6C, 6D).
