3 years ago: incidental MRI finding of 1.5 mm stable pituitary lesion. 2 years ago: ER b/c headache & vomiting- MRI showed enlarged pituitary lesion w/ hemorrhage. Reason unknown. Last 2 years: 2 MRIs have shown stable & small pituitary lesion. Neurosurgeon suspects Rathke's Cyst or Cystic Pituitary Adenoma. In 2 days: cosmetic open rhinoplasty w/osteotomy, under general anesthesia. Could the general anesthesia or osteotomy possibly disrupt the pituitary lesion? Should I cancel the surgery?
