Table 2.
Tumor size, resection success and anatomic pathology for 344 consecutive patients who underwent transsphenoidal resection of a pituitary mass at the authors’ institution between January, 2006, and December, 2012. PRL = prolactin; GH = growth hormone; LH = luteinizing hormone; FSH = follicle stimulating hormone; ACTH = adrenocorticotropic hormone.
