 Postoperative changes are again noted from previous left frontal temporal craniotomy/cranioplasty. There is no intracranial mass or mass effect or pathologic enhancement within the brain to suggest metastatic disease. The ventricles and sulci are within normal limits. No evidence of ischemia or hemorrhage. No hydrocephalus or extra-axial collections. There is an incidental left cerebellar developmental venous anomaly as well as a mega cisterna magna. Paranasal sinuses and mastoid air cells are clear.Again seen is irregularity involving the left lateral orbital wall and sclerosis with mild expansion involving the left greater sphenoid wing as demonstrated on recent CT and MRI. No suspicious enhancement or discrete intraorbital mass is seen to suggest residual or recurrent tumor. Again noted is prominence of the left V2 nerve and mild enlargement of the left foramen rotundum, similar to prior, in the region of the previously seen mass. The optic nerves are normal in size and signal intensity, and are symmetric bilaterally. No retrobulbar mass, chiasmatic mass, or parasellar abnormality is seen. Extraocular muscles are unremarkable.
1. Posttreatment changes involving the left lateral orbit/sphenoid wing without evidence of recurrent tumor.2. No evidence of intracranial metastatic disease.
