Novel burr hole dilator for endoscopic surgery for intracranial hemorrhagic lesion: technical note.
When performing burr hole endoscopic neurosurgery, it is necessary to get enough surgical corridor. We have used various instruments to extend burr hole size, but it was cumbersome to use so many tools. ⋯ Our dilator for expanding a burr hole improves the work of endoscopic surgery on intracranial hemorrhagic lesions.

Tethered cord syndrome (TCS) refers to a clinical constellation of signs and symptoms associated with tension in the spinal cord and associated with pathologies related to abnormally low-lying conus medullaris. As minimally invasive spinal operations have become more prevalent in the past decade, we applied expanding indications to selected intradural procedures, such as tethered cord release (TCR). We present the first series of minimally invasive muscle-sparing TCR in the pediatric population. ⋯ Minimally invasive TCR is a safe and represents a viable alternative to the open approach with advantages such as minimal estimated blood loss, shortened length of stay, and postoperative pain control.

This study aimed to report the case of a patient who presented with depression, cognitive impairment, ataxic gait, and urinary incontinence associated with vitamin B12 deficiency. ⋯ This study was novel in reporting subacute combined degeneration of the spinal cord and hydrocephalus associated with vitamin B12 deficiency in adults.

The rectus capitis lateralis (RCL) is a small cervical muscle that arises from the transverse process of C1 and is intimately related to the jugular process and jugular foramen. We describe its morphology, neurovascular relationships, and its utility as one of the key surgical landmarks in approaches to the jugular foramen. ⋯ The RCL usually is preserved unless jugular process needs to be removed to expose the jugular foramen. The RCL is an important surgical landmark for the early identification of the vertebral artery, internal jugular vein, facial nerve, and CNs IX-XII in approaches to the jugular foramen.

Laterally located intracranial mature teratomas are rare entities. We report an extremely rare case of an extra-axial mature teratoma of the left petrous temporal bone in an infant who was managed surgically. This is the second reported case of a mature teratoma of the petrous temporal bone in an infant.
