In this study, we investigated if and when dural tenting sutures are necessary during craniotomy. ⋯ Placing dural tenting sutures is an important technique for ensuring hemostasis. However, when not needed, they seem to cause inadvertent complications. As our results suggest, knowing when and where to use them is equally important.

Primary Intraparenchymal Meningiomas: A Case Report and a Systematic Review.
Primary intraparenchymal meningiomas are exceedingly rare and often challenging to diagnose, given their misleading radiologic features. It is hypothesized that they arise from the cap cells of the pia mater that enter the brain via penetrating blood vessels during brain development. We systematically reviewed and analyzed previously reported features of primary intraparenchymal meningiomas in terms of radiography, presenting symptoms, and histopathology. ⋯ We present a comprehensive analysis of every reported primary intraparenchymal meningioma. Because of their rarity and capacity to mimic other more common intra-axial tumors, they represent a diagnostic challenge. This systematic review highlights the importance of paying attention to atypical intra-axial lesions, with a particular reflection on the discrepancy between clinical characteristics and imaging features.

Multicenter Study
Relative risks and benefits of crossing the cervicothoracic junction during multilevel posterior cervical fusion: A multicenter cohort.
To compare the clinical and radiographic outcomes and complications in patients undergoing multilevel posterior cervical fusion surgery, ending at C7 or crossing the cervicothoracic junction (CTJ). ⋯ Crossing the CTJ during multilevel posterior cervical fusion surgery reduced instrument failures at LIV, but increased the surgical invasiveness and perioperative and postoperative complications.

Eponyms of cranial neurosurgical instruments: an international collaboration to optimize the field of neurosurgery.
The basic set of a cranial instrument tray is filled with eponyms of surgical instruments named after surgeons and physicians from all corners of the medical world. These include pioneers like Castroviejo, Doyen, Frazier, Gigli, Mayfield, Raney, Weitlaner, and Yaşargil. These innovators have always strived to enhance and simplify procedures, ultimately shaping the way we perform surgery today. ⋯ Additional information was obtained via personal contact with American and European medical institutions, libraries, museums, as well as with the surgeons' family members and their perspective foundations. Remembering the life stories of the inventors behind commonly used eponyms in the operating theater reminds us of the long history of even the most rudimentary neurosurgical tool. This unrelenting strive for perfection reminds us, as surgeons, of our duty to continuously assess and improve our surgical tools and processes for the benefit of our patients.

Secondary adrenal insufficiency (sAI) is a severe endocrinologic complication associated with nonfunctioning pituitary adenoma (NFPA). However, its prevalence is not simply related to tumor size. In this study, we aimed to detect the clinical characteristics of NFPAs that cause sAI. ⋯ The NFPAs that occupy the sella space and compress the walls on both sides of the cavernous sinus, but do not penetrate them, have a higher risk of developing sAI. This type is more common in males and is seen even in patients without visual field disturbances. This clinical finding will be beneficial in management of patients with NFPA.
