Female, 56 years old, with diplopia. Preoperative planning for biopsy. Evidence of left pterional craniotomy is again seen. Postcontrast images demonstrate patchy gyriform enhancement through the left frontal lobe with scattered additional areas of enhancement along the left frontal horn ependyma and along the left insula and temporal lobe. These findings are not significantly changed. The degree of associated T2 hyperintensity within the adjacent parenchyma is also unchanged.A nodule of enhancement within the left middle cranial fossa spanning both the intracranial extracranial spaces is also largely unchanged. Heterogeneous enhancing soft tissue is also redemonstrated within the left orbital apex, extending along the anterior clinoid process to involve the cavernous sinus. This finding also appears similar to the prior examination.
1.Stable patchy gyriform enhancement within the left cerebral hemisphere.2.Stable nodule of enhancement along the anterior left temporal lobe spanning both intracranial and extracranial spaces.3.Stable heterogeneous enhancement within the left orbital apex and cavernous sinus.
