Secondary malignant neoplasm of brain [C79.31], Reason for Study: ^Reason: history of brain metastases. follow up MRI History: none There is about 6.9mm (RL) x 8.6mm (AP) x 7.5mm (CC) peripheral enhancing intra axial lesion on the right superior frontal gyrus. Comparing to prior scan, the size of the lesion has been decreased, however the extent of surrounding edema appears to be stable.There is no other abnormal enhancing lesion seen on this scan.Evidence of prior bifrontal craniotomy is again seen, unchanged.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
1. Interval decrease in size of the right superior frontal gyrus metastatic lesion since prior scan.2. No evidence of new metastatic lesion.
