Detection of suprasellar subarachnoid hemorrhage using intraoperative magnetic resonance imaging during endoscopic transsphenoidal resection of pituitary neuroendocrine tumors.

ABSTRACT:

Background

Endoscopic transsphenoidal surgery (ETSS) is considered safe for the treatment of pituitary neuroendocrine tumors (PitNETs). Postoperative subarachnoid hemorrhage (SAH) is extremely rare in patients with PitNET, and information regarding the source of hemorrhage in such cases is limited.

Case description

Herein, we report the cases of a 59-year-old man and a 49-year-old woman who underwent ETSS for nonfunctioning PitNETs. Gentle subcapsular removal was performed, and no cerebrospinal fluid leakage was observed during the procedure. We routinely perform intraoperative magnetic resonance imaging (iMRI) to confirm the presence of residual tumors. In the former case, conservative treatment was selected because minimal bleeding was observed in iMRI. In the latter case,
