Stereotactic biopsy procedures, in which a computer-based, three-dimensional-image-guided system accurately locates patients' brain tumors, are relatively new diagnostic methods. Complications from stereotactic biopsy procedures are minimal compared with open craniotomy procedures because they are performed with local anesthesia. Perioperative nurses should have knowledge of and be trained in stereotactic biopsy procedures to ensure optimal care for patients undergoing these procedures.

Objective And Importance: Compression of the optic nerve by a dolichoectatic internal carotid artery is a rare and correctable cause of visual loss.
Clinical Presentation: A young woman presented with right eye visual loss without obvious cause and was found to have compression of the right optic nerve by the ipsilateral internal carotid artery, as revealed by magnetic resonance imaging.
Intervention: Pterional craniotomy and decompression of the optic nerve by unroofing the optic canal resulted in improvement of vision in the affected eye.

We report the case of a 61-year-old man with an unusual intrasellar vascular malformation, who presented with symptoms of hypopituitarism and whose neuroradiologic evaluation mimicked a pituitary macroadenoma. The histopathologic and radiologic findings are discussed. This rare lesion should be considered in the diagnosis of a sellar mass lesion.

In 89.5% of cases a definitive diagnosis was made by stereotactic biopsy with a major complication rate of 2.
