Moreover, in the present case, the suprasellar tumor remained visible after autologous peripheral stem cell transplant, likely due to the residual pituitary adenoma.
The careful analysis of possible pituitary embryonic malformations points out their significance for proper localization of extrapituitary adenomas. His ophthalmoplegia at presentation persisted with no further deficits. None of the 22 pituitary adenomas and the eight papillary craniopharyngiomas analyzed presented any sequence alterations.
Descriptions of benign tumors, especially in adult patients, are rarer.

Three adenomas were located in the cavernous sinus, 1 in the sphenoid sinus, and 1 in the ethmoidal cells. Transsphenoidal surgery is minimally invasive, but transcranial surgery may remain a universal option for the treatment of suprasellar lesions.

The extent of resection was significantly associated with cavernous sinus invasion.
Some silent adenomas such as silent corticotroph adenomas follow a more aggressive course, necessitating closer surveillance. The pars tuberalis may be different from the pars distalis, and each subtype of adenohypophyseal cells may have different migration characteristics, which leads to different proportions of each hormone-secreting subtype in SPAs and EPAs.
This mixed ACTH adenoma -gangliocytoma is the first example to present clinically with an opportunistic infection. Descriptions of benign tumors, especially in adult patients, are rarer.
The present study assessed continuous microscopic surgeries for pituitary adenomas performed by an author of the present study between to The lesion was removed by transphenoidal surgery and the biopsy confirmed the lesion to be pituitary adenoma.
