Multiple new (since normal CT/MRI studies from one month prior) hypodense lesions are demonstrated within the cerebral white matter bilaterally, the largest measuring 12 x 11 mm in within the left corona radiata, with ring enhancement and surrounding oedema. There is mild local mass effect, no midline shift. Ventricular and sulcal pattern remains within normal limits. Significant streaking and motion artefact noted through the base of skull and posterior fossa limits assessment.
