No evidence of parenchymal edema or mass effect is detected. Diffusion-weighted images are within normal limits. No pathologic parenchymal or extra-axial enhancement is observed. No evidence to suggest acute intracranial hemorrhage or any abnormal extra-axial fluid collection is seen. Ventricular size and morphology are within normal limits. Bone marrow signal characteristics are unremarkable.
