FIG 2. Axial MR images obtained at the level of the temporal lobes. T1-weighted postcontrast image (A) shows a rim-enhancing, multilocular masslike lesion within the anterior left temporal lobe (arrows). The enhancement corresponds to the chronic granulation tissue surrounding the foreign body. FSE T2-weighted image (B) shows surrounding confluent T2-hyperintense vasogenic edema. Susceptibility effect (arrow) was preoperatively thought to reflect old blood products (hemosiderin) but most probably was the foreign body itself (likely fiberglass, according to the surgeon).
