Axial FLAIR image shows high signal intensity consistent with edema at subfrontal region and optic chiasm. Review Wrapping: reinforcement/wrapping of certain (anatomic configuration, location etc) IC aneurysm with muslin, cotton gauze in addition to clipping Muslinoma: FB inflammatory reaction, arachnoiditis/ inflammatory mass Sx: Visual loss (A-com); 1-24mo after surgery, Headache, Seizure, malaise, ischemic (vasculitis) MRI: rim enhancing collection/ relatively low SI on T2 Treatment: corticosteroid, immunosuppressant, surgical lysis of adhesions or observation Prognosis: unpredictable Reference Brochert, A. et al.
