Pursue local opinion: Your vague description does not provide enough detail to speculate on the cause. A simple skull x-ray might show a dark void where a hole was created for the surgery, but the type of x-ray vs CT scan vs MRI is not clear fro the post. I would have a local physician review her history and the x-ray findings to come up with an answer.
