case_images: Clinical pictures of patients. (A) Cranial T2 fluid-attenuated inversion recovery sequence magnetic resonance imaging scan showing an irregular mass of abnormal signal in the anterior portion of the left temporal lobe. The borders between the mass and surrounding tissue are not clear. (B) Abnormal signal disappeared after resection of lesioned tissue. (C, D) Brain histopathology showing extensive degeneration and necrosis of glial cells, hyperplasia of peripheral glial cells, and infiltration of peripheral lymphoid tissue.

case_images: Cranial MRI scans (T2 fluid-attenuated inversion recovery sequence;  Figure 1A ) showed a left temporal lobe mass with large surrounding edema and midline shift. The postoperative primary lesion on the repeat MRI ( Figure 1B ) disappeared, and brain histopathology ( Figures 1C, D ) showed extensive degeneration and necrosis of glial cells, hyperplasia of peripheral glial cells, and infiltration of peripheral lymphoid tissues, which led to a final diagnosis of REP.
