Gamma Knife radiosurgery (GKRS) is an established treatment modality for vestibular schwannomas (VSs). The tumor control and hearing preservation rates suggest that GKRS is a good alternative treatment for small- and medium-size VS. Data are lacking from India regarding GKRS for VSs. Our aim was to find the hearing preservation and tumor control rates and the factors contributing to these. ⋯ For most patients with small VSs, GKRS will be an effective alternative treatment to microsurgery with retained serviceable hearing and good tumor control.

Extradural benign cysts located in close proximity to the facet joints are called juxtafacetal cysts. Only about 3.5% of such cysts occur in the cervical spine. To our knowledge, there has been no published article on the endoscopic resection of a cervical facet cyst, and this is the first report. ⋯ The findings suggest that ankylosing spondylitis may cause formation of a juxtafacetal cyst at the mobile levels in a relatively less mobile cervical spine. The endoscopic resection of such cysts is a minimally invasive novel procedure that can cure such patients successfully without unwanted fusion surgery.

Relapse of primary central nervous system (CNS) lymphoma (PCNSL) occurs primarily at the initial site. Relapse outside the CNS is rare. ⋯ Here we report the first case of extra-CNS relapse of PCNSL around the site of VPS in the abdomen after intensive chemotherapy. Neurosurgeons should be aware of a potential risk of PCNSL spread along the VPS.

We sought to differentiate glioblastomas from solitary brain metastasis using arterial spin labeling perfusion (ASL)- and diffusion tensor imaging (DTI)-derived metrics. ⋯ A combination of ASL- and DTI-derived metrics of the peritumoral part can be used for differentiation of glioblastomas from solitary brain metastasis.

The preservation of acceptable facial nerve (FN) function after surgery is the key concern for most patients with vestibular schwannomas (VS). To assess predictive factors of early postoperative and long-term FN function in patients harboring large VS operated with a FN-sparing technique. ⋯ As long as the extent of resection or additional Gamma Knife surgery have not been identified as predictive risk factors of postoperative FN palsy, we suggest that optimal resection is the main option for patients harboring large VS.
