Initial presentation following seizure. Axial brain NECT of the brain (A) with a superficial coarse calcification in the right frontal lobe. FLAIR sequence axial brain MRI (B) shows hyperintensity surrounding the same coarse calcification in the superficial right frontal lobe, which revealed ringlike enhancement following contrast administration (C).

A nonenhanced computed tomographic (CT) scan of the brain (Fig 1A) revealed a coarse calcification in the right frontal lobe with associated edema. A subsequent brain magnetic resonance imaging (MRI) scan (Figs 1B and 1C) demonstrated T2/FLAIR hyperintensity surrounding a coarse calcification in the superficial right frontal lobe corresponding to the same lesion identified on CT, which revealed ringlike enhancement following contrast administration.
Routine followup exam. FLAIR sequence axial brain MRI (A) 4 months later shows minimal hyperintensity and complete resolution of enhancement on postcontrast T1 sequences (B).

The first 4-month followup MRI showed minimal residual perilesional edema, and the enhancement was completely resolved (Fig. 2).
First seizure in 10 years. FLAIR sequence axial brain MRI (A) shows hyperintensity surrounding a stable right frontal lobe calcification, which revealed ringlike enhancement following contrast administration (B).

CT again revealed a stable right frontal lobe calcification (Fig. 3A), and MRI again demonstrated T2/FLAIR hyperintensity surrounding the same calcification, associated with ringlike enhancement following contrast administration (Fig 3B).
