Suture material-induced granuloma. Axial T2-weighted (a, b) and unenhanced T1-weighted (c) images and coronal contrast-enhanced T1-weighted (d) showing a mass (arrow) in the right frontal superior gyrus with low signal on both T1- and T2-weighted sequences, surrounded by vasogenic edema (arrowheads), with rim enhancement. Some tubers are detectable in the axial images as the patient was affected by tuberous sclerosis
