37 year old female with history of brain tumor. Evidence of a bifrontal high convexity frontal craniotomy which extends across the midline. Some soft tissue density with central enhancement appears to be along the inner table of the craniotomy flap. This finding could represent epidural thickening as result of surgery. Due to high positioning of the craniotomy it is not possible to determine with certainty whether there is residual tumor in this location. The brain parenchyma immediately inferior to the flap however appears normal and demonstrates no evidence of any edema, encephalomalacia or any abnormal enhancement. Although this exam does not demonstrate any definitive evidence of tumor, further evaluation with MRI would be more definitive. The findings in this exam are believed to be entirety post operative change. Multiple thick dural based calcification in the area of surgery is noted which are believed to represent dural calcific plaques.
No definitive evidence of recurrence of tumor. Follow up exam and MRI is recommended.
