Video Transcript

In conclusion, postoperative MRI confirmed the total removal. Histology was a pilocytic astrocytoma. The patient presented conjugate eye movement disturbance that resolved almost completely following six-month orthoptic rehabilitation. No recurrences were seen at follow-up.

Here are some images of postoperative MRI. Sagittal T2-DRIVE sequences showing the surgical cavity. Sagittal T1 contrast injection and axial FLAIR showing a subtotal removal of the tumor. And axial T1 in neuronavigation showing a very nice surgical cavity.
