Abstract
According to current statistics, pituitary neuroendocrine tumors (PitNETs) are quite common, occurring in approximately 1 in 1,100 individuals in the general population, accounting for 16.4–25 % of all central nervous system and intracranial tumors.
These clinical observations describe two cases of pituitary MR-elastography in patients with PitNETs (a 45-year-old woman with a GH-secreting tumor; a 56-year-old man with a non-GH-secreting tumor), including the characteristics of the patients’ complaints, medical history, clinical presentation, preoperative MR-elastography results, intraoperative presentation, and surgical treatment outcome.
Preoperative determination of pituitary neuroendocrine tumor consistency can alter surgical technique and influence the surgical approach, treatment outcome, and reduce the risk of complications, reoperation, or the need for postoperative radiosurgery.
