Surgical Management of Extradural Tumors at the Craniovertebral Junction - Insights from a Tertiary Care Center.
Craniovertebral junction (CVJ) tumors are challenging due to their unique anatomical location. This study aimed to evaluate the complexities in dealing with such precarious CVJ extradural lesions over the decade. ⋯ This retrospective study provides valuable insights into managing extradural CVJ tumors and highlights the importance of individualized approaches for optimal outcome.

This study aimed to establish a predictive nomogram model for recollapse of fractured vertebra after posterior pedicle screw fixation in thoracolumbar fractures (TLFs). ⋯ A clinical nomogram incorporating 4 variables was constructed to predict fractured vertebra recollapse after posterior pedicle screw fixation for TLFs. The nomogram demonstrated good calibration and discriminative abilities, which may help clinicians to make better treatment decisions.

Malnutrition frequently is associated with increased complications and worse outcomes after surgery. The purpose of this study was to determine whether malnutrition status determined using the Geriatric Nutritional Risk Index (GNRI) can serve as an independent risk factor for complications in patients undergoing anterior cervical discectomy and fusion (ACDF). ⋯ In elderly patients after ACDF, malnutrition determined using GNRI is an independent risk factor for 30-day complications, readmissions, prolonged hospital length of stay, and nonhome discharge.

Short-lasting cough-associated headache (CAH) in patients with Chiari I malformation (CMI) is believed to be due to transient worsening of cerebrospinal flow (CSF) obstruction at the foramen magnum. We assessed changes in CSF flow in response to coughing in CMI patients with CAH and compared with those without CAH and healthy participants (HPs) using real-time magnetic resonance imaging. ⋯ A decrease in CSF flow after coughing in CMI patients with CAH supports the notion that CAH is caused by transient worsening of CSF flow obstruction at the foramen magnum.

Multiple intracranial schwannomas of the vestibular and trigeminal nerves: Technical note.
A schwannoma is a nerve sheath tumor that is formed by Schwann cells. Vestibular schwannomas are thought to account for the majority of intracranial schwannomas. Nonvestibular schwannomas account for about 10%, about half of which are trigeminal schwannomas. Multiple intracranial schwannomas originating from different cranial nerves are extremely rare. ⋯ The presence of multiple intracranial schwannomas is extremely rare in neurosurgical practice and can change the intraoperative strategy and the course of the surgery.
