Light microscopy revealed diffuse large B-cell lymphoma with follicular G3 areas (Figure 3).
Followup axial (a) and sagittal (b) T1-weighted magnetic resonance imaging. Postoperative contrast enhanced magnetic resonance imaging scans obtained one year after the operation, local radiotherapy, and chemotherapy demonstrated no evidence of relapse.
