MRI of the brain requested 10 weeks post-injury because of the headache aggravation superimposed by diplopia. A Coronal T2-weighted MRI revealed a large arachnoid cyst in the left middle cranial fossa containing fluid of CSF intensity (brown asterisk) extending to subdural space(black asterisks).The membrane separating arachnoid cyst and the subdural hygroma is clearly obvious (yellow-filled arrows in the main image and inset). Note: For better delineation of the upper part of the cyst membrane, the inset has been artificially inverse-colored. B Axial T2-weighted image revealed a large left frontotemporoparietal subdural hygroma leading to severe midline shift and nearly complete effacement of left lateral ventricle C Axial T2-weighted image showing the rectangular arachnoid cyst at the middle fossa corresponding to Galassi type II arachnoid cyst
