Craniofacial resection (CFR) for advanced sinonasal malignant tumors (SNMTs) is mandatory for radical resection. Surgeons must be aware of perioperative complications and long-term outcome because this procedure is extremely invasive, especially when the tumor involves the anterior skull base. ⋯ CFR and postoperative radiotherapy are safe and effective for treating advanced SNMTs. Extended CFR, including radical orbital exenteration, may contribute to good long-term outcomes. A diverse surgical team may help perform radical resection and reconstruction in patients with advanced tumors.

Thalamic gliomas are rare tumors that constitute 1%-5% of all central nervous system tumors. Despite advanced techniques and equipment, surgical resection remains challenging because of the vital structures adjacent to the tumor. Intraoperative magnetic resonance imaging (MRI) might play an active role during brain tumor surgery because it compensates for brain shift or operation-induced hemorrhage, which are challenging issues for neurosurgeons. ⋯ With improvements in neurosurgical techniques and equipment, surgical resection is considered feasible in patients with thalamic gliomas. Intraoperative MRI may be helpful in achieving the maximal resection rate with minimal surgical-related morbidity. However, because of severe disease progression, the overall prognosis is unfavorable.

Intraventricular hemorrhages (IVHs) caused by ruptured cerebral aneurysms often have poor outcomes. Treatment challenges include comorbidities, increased intracranial pressure caused by IVH, and risk of rebleeding. ⋯ A hybrid OR may contribute to a combined neuroendoscopic and endovascular treatment for ruptured cerebral aneurysms with severe intraventricular hemorrhage.

Isolated cortical venous thrombosis is very rare and poorly understood. The clinical presentation is also not well described in the literature. We report here a case of isolated cortical venous thrombosis that mimicked cortical subarachnoid hemorrhage (SAH). ⋯ The patient had no recurrence of symptoms. If a cord sign is present on noncontrast CT images, further studies (MRI/magnetic resonance venography or TFCA) should be performed in a step-wise manner. Such considerations could prevent a fatal outcome and poor prognosis.

Tuberculum sellae meningiomas (TSM) arise from the dura mater of tuberculum sellae, limbus sphenoidale, and chiasmatic sulcus and cause asymmetric visual disturbances. In this study, we analyzed the laterality of the origin of TSM and discussed its clinical implications on immediate and long-term visual outcomes. ⋯ Most TSMs that originated from the dura of one lateral end portion of the tuberculum sellae correlated with asymmetric visual symptoms and poor visual outcomes. This microsurgical feature should be considered in the planning of optimal surgical strategy to achieve favorable outcomes.
