Case Study Series: Chordoma
This patient was a 10-year-old boy with partial paralysis in his left eye. He technically had sixth nerve palsy, or abducens nerve palsy, which is a disorder associated with dysfunction of cranial nerve VI (the abducens nerve). It makes it nearly impossible to turn out the affected eye and commonly leads to double-vision.
This was an acute event and when he was brought into the hospital, his imaging showed a very large mass compressing his brain stem.
