There is a well-defined solid-cystic lesion in the left temporal lobe with mild surrounding vasogenic edema. The solid component of the lesion shows vivid enhancement on post-contrast images with no evidence of calcification or hemorrhage or flow void within it. On the FLAIR sequence, cystic areas show hyperintensity relative to CSF.
Small arachnoid cyst/ Mega cisterna magna seen in the posterior fossa in the midline.
