Figure 1 Magnetic resonance imaging and pathology at first recurrence. A-C: Brain magnetic resonance imaging (MRI) T1-weighted postcontrast image (A) axial, (B) sagittal, (C) transverse,which indicates hyperintensity and intracapsular hypointense signals after contrast enhancement in the right cerebellopontine angle tumor (arrow); D and E: Axial MRI T2-weighted image shows a heterogeneous lightly hypointense node beside the hyperintense capsule, while axial MRI T1-weighted image (E) shows a heterogeneous lightly hyperintense node and hypointense capsule (October 24, 2000, before the 2^nd operation); F: Histology shows recurrent melanoma (hematoxylin-eosin staining, magnification × 400).
