Pilocytic astrocytoma and hypertrophic olivary degeneration


Pilocytic astrocytomas are not infrequently encountered in young adults, often in less usual locations and with less typical appearances. 

In this instance the tumor and subsequent resection resulted in hypertrophic olivary degeneration. I called the patient at home to ask if they had palatal myoclonus, a typical neurological symptom. Once I managed to A) convince him I was being serious, and B) got him to look in the mirror with his mouth open while I waited on the phone, I was a little disappointed to find out that his palate exhibited no abnormal motion. Sad but true. Excellent for the patient.
