Nonfunctioning pituitary adenomas are the most common pituitary adenomas in adults and cause significant morbidity unless adequately treated. ⋯ Nonfunctioning pituitary adenomas present frequently as mesoademonas and giant adenomas. Patients with these tumors may have subclinical visual or hormonal deficits at the time of diagnosis. Early and effective surgical treatment is essential for rapid recovery of visual and/or hormonal deficits, particularly in symptomatic cases.

Extraforaminal lumbar disc herniation (EFLDH) accounts for 7%-12% of all lumbar disc herniations. We report on a surgical technique for EFLDH, which requires only minimal resection of the facet joint and also allows access to the preforaminal space, if necessary. ⋯ Disc fragment herniectomy through a facet joint quadrantectomy for EFLDH is a safe and minimal invasive technique resulting in very satisfactory results. Preservation of facet joint stability and the possibility to convert to a classic approach to reach for preforaminal components, if necessary, are major advantages of this technique.

Spinal intradural tumors are usually removed with laminectomy/laminotomy with a midline dural incision. Pain, discomfort, postoperative kyphosis, and instability may be minimized with unilateral microsurgery. ⋯ Neurologic and oncologic results were good and postoperative pain and discomfort were reduced. Stability was preserved with a unilateral technique. No bracing was necessary, permitting early rehabilitation.

The proximal segment of the anterior cerebral artery (A1) is among the most uncommon locations for occurrence of an intracranial aneurysm. These aneurysms may be missed if small or misinterpreted when they are near the internal cerebral artery bifurcation or Anterior Communicating Artery region. The association with congenital vascular anomalies and multiplicity makes them unique. ⋯ A1 aneurysms are rare, with wide anatomic variations. In this article, we discuss those variations in detail with illustrative cases and pictures. We also discussed the microsurgical and endovascular strategies to encounter them highlighting the technical challenges.

Hybrid microscopic-endoscopic surgery for craniopharyngioma in neurosurgical suite: technical report.
The best chance of curing craniopharyngioma is achieved by microsurgical total resection; however, its location adjacent to critical structures hinders complete resection without neurologic deterioration. Unrecognized residual tumor within microscopic blind spots might result in tumor recurrences. To improve outcomes, new techniques are necessary to visualize tissue within these blind spots. We examined the success of hybrid microscopic-endoscopic neurosurgery for craniopharyngioma in a neurosurgical suite. ⋯ Simultaneous microscopic and endoscopic observation with the use of dual monitors in a neurosurgical suite was ergonomically optimal for the surgeon to perform microsurgical procedures and to avoid traumatizing surrounding vessels or neural tissues. Hybrid microscopic-endoscopic neurosurgery may contribute to safe, less-invasive, and maximal resection to achieve better prognosis in children with craniopharyngioma.
