Well defined exta-axial, intradiploic cystic space occupying lesion in left fronto-temporal bones, appears heterogenous in T1W and hyperintense in T2Wimages, heterogenously hyperintense in FLAIR sequences, not enhanced post contrast, shows restricted diffusion in DW/ADC sequences.
causes mass effect, buckling adjacent brain parenchyma, the adjoining enhanced dura is pushed medially, and midline shifting to right side.
causes bone remodeling abutting left orbital roof.
