    BackgroundVenous sampling methods are valuable tools for the diagnosis of pituitary adenomas. However, these interventions also have complications, which may complicate the treatment process.Case DescriptionA 49-year-old female pituitary adenoma patient with preliminary diagnosis of Cushing disease underwent cavernous sinus sampling (CSS) to delineate the adenoma. The microguidewire broke during the procedure, and the distal part of the microguidewire had to be left within the right cavernous sinus. Eventually, the broken part of the guidewire was removed after the removal of the tumor through an endoscopic endonasal approach.ConclusionsCurrent surgical experience on endoscopic skull base surgery allows management of diagnostic complications related to the cavernous sinus, such as safe access to materials which were inadvertently left during CSS, without the necessity for further interventions.Copyright © 2017 Elsevier Inc.
