Minimal enhancement within the pons, which may be vascular in nature, is unchanged. No new enhancing lesions are detected.Elsewhere brain morphology and signal characteristics are unremarkable. Diffusion weighted images are normal. No evidence of significant intracranial hemorrhage or any abnormal extra-axial fluid is seen.
