MRI study of the patient's metastatic lesion. Initial sagittal (A) and axial (B) magnetic resonance imaging (MRI) scans with contrast of the head demonstrating a well-circumscribed enhancing lesion with surrounding edema in the pons. Postoperative MRI (C-D) with contrast demonstrating a gross total resection of the solitary lesion with no evidence of residual disease. MRI with contrast at 10 years (E-F) after the original craniotomy showed no signs of recurrent disease. Used with permission from Barrow Neurological Institute, Phoenix, Arizona.

FIG1
Because of the recent onset of her symptoms, a magnetic resonance imaging (MRI) study was performed, which demonstrated a 2.0 x 2.1 cm, well-circumscribed, contrast-enhancing lesion centered at the pontine-medullary junction (Figure 1A, 1B). Postoperative MRI demonstrated a gross total resection (Figure 1C, 1D), with only minor areas of enhancement that were interpreted as postoperative hyperemia. Remarkably, throughout this time, she remained neurologically stable compared to her postoperative state, with no radiographic (Figure 1E, 1F) or clinical signs of tumor recurrence.
