Optic pathway gliomas (OPGs) are relatively rare, and their presentation after the first decade of life is even less common. Although many treatment options exist, surgery is typically reserved for tumors significantly compressing surrounding structures. Pregnancy can complicate the management of these tumors, as fetal developmental considerations limit the ways in which they are imaged and treated. ⋯ While OPGs are typically benign tumors, pregnancy complicates their management significantly. Contrast media and anesthesia pose significant risks to the fetus, while pregnancy may contribute to increased rates of tumor growth and clinical deterioration. Managing OPGs in pregnant patients thus requires balancing the risks to the fetus and patient.

Intracerebral hemorrhage, seizures, neurologic deficits, and cognitive impairments due to brain AVM in childhood are incriminating for brain and executive function with sequelae for further social life. Long-term follow-up data on brain AVM in young patients are rare, making it difficult to compare and evaluate treatment risks and outcomes. ⋯ Favorable outcome was achieved in the majority of patients. The rate of neurologic improvement and participation in social life was very high in the 2 groups.

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.

Although superficial temporal artery (STA) to middle cerebral artery (MCA) anastomosis is a beneficial treatment for hemorrhagic moyamoya disease, indeterminate mechanisms can cause rebleeding even after successful bypass surgery. We describe a case with a prominent collateral from the lenticulostriate artery (LSA) causing multiple recurrent hemorrhages after successful STA-MCA anastomosis. ⋯ Lenticulostriate anastomotic branches distributed medially to the anterior cerebral artery territory should be given more attention as an intractable cause of hemorrhage after successful STA-MCA anastomosis. Although challenging, direct bypass targeting the area reached by collateral vessels could be considered an alternative treatment strategy for this pathologic condition.

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.
