Two right frontal and left temporal cortical lesions are seen measuring about 2 x 1.5 x 1.2 cm and 2.2 x 1.6 x 1.5 cm at their maximal axial and craniocaudal dimensions respectively. The lesions show high signal 'bubbly appearance' on T2 WIs, low signal on T1 WIs. The lesions exert minimal mass effect on the nearby cortical sulci, and on the left there is also scallop the inner table of of the skull vault.
