Radiation Necrosis . Magnetic resonance images at presentation of a 73-year-old female with a history of trigeminal neuralgia, which was treated previously by TomoTherapy radiosurgery, shows significant mass effect in close proximity to Meckel's cave. (A) Axial T1-weighted image with contrast; (B) axial FLAIR; (C) coronal T1-weighted image with contrast; and (D) coronal T2-weighted image. Used with permission from Barrow Neurological Institute.

During this time, a magnetic resonance image (MRI) study was ordered, and a 2.7x1.5x1.7 cm heterogeneously enhancing mass in the right mesial temporal lobe with perilesional edema was incidentally found (Figure 1).
Postoperative Resection . Postoperative magnetic resonance image showing excellent resection of enhancing portion, pathologically confirmed to be radiation necrosis.
