Metastatic subdural hematoma with dural metastasis in the setting of an underlying malignancy is a rare condition that is difficult to diagnose and associated with a poor prognosis. Knowledge of this rare entity is of a paramount importance to neurosurgeons, as its diagnosis may affect the management plan and overall survival. Here, we report a rare case of atraumatic subdural hematoma with dural metastasis in a patient with poorly differentiated adenocarcinoma of unknown origin. ⋯ Metastatic subdural hematoma with dural metastasis should be included in differential diagnosis of subdural hematoma, especially in patients with atypical presentation and in the presence of an underlying malignancy, as it may affect the management plan and overall survival.

To study improvements in outcomes after surgery for intracranial meningiomas. ⋯ Meningioma surgery as well as patient population changed over the 2 decades considered in this study. We observed higher rates of gross total resection in the later period and the perioperative outcomes improved or were unchanged, which signifies better long-term outcomes, RFS, and OS.

Case Reports
Rosette forming glioneuronal tumor in the optico-chiasmatic region-a novel entity in a new location.
Rosette-forming glioneuronal tumour [RGNT] is a relatively rare entity first identified as a separate entity in 2002. We are reporting the second case of RGNT in the opticochiasmatic region. ⋯ Although initial reports were predominantly in the fourth ventricle, many recent reports have identified the possibility of its occurrence outside fourth ventricle in pineal gland, spinal cord, septum pellucidum, lateral ventricle, and suprasellar region. To date, only 1 case of RGNT involving the opticochiasmatic region has been reported in a patient with neurofibromatosis type 1. Genetic analysis of this rare tumor identified 3 hotspots involving somatic mutations of FGFR-1 and PIK3CA and a germline mutation involving PTPN11, which can be targets for therapeutic intervention in cases where complete resection is not possible. To the best of our knowledge, we report the first case of RGNT involving the opticochiasmatic region without any syndromic association. Other cases of RGNT with syndromic associations provide us with insight into possible therapeutic interventions.

Esophageal injury is a severe surgical complication of a transsternal approach to high thoracic vertebral metastasis, which can result in mediastinitis and life-threatening consequences. A covered stent can be placed in the esophagus to prevent mediastinal leakage. However, tracheomalacia is a rare complication following esophageal stenting. ⋯ Esophageal stenting can be used to prevent mediastinal leakage due to esophageal injury in the transsternal approach for high thoracic vertebral metastasis, but the stent might be a cause of tracheomalacia. Stent removal should be considered if upper airway obstruction occurs. Awareness of the radial force of the stent, esophageal composition (e.g., status post suture repair), and esophageal diameter must be considered for optimal stent tolerance to avoid complications.

Gamma Knife radiosurgery was introduced in the 1960s and is currently used worldwide. The internet has become a foremost source of information used by patients and their families. In this study, we aim to evaluate the accuracy and reliability of the Gamma Knife radiosurgery-related YouTube videos. ⋯ Patients and caregivers turn to online sources to gather information about the disease. However, the available YouTube published videos are published without proper academic monitoring, as in such a free platform, published videos tend to catch a general audience for different purposes, which leads to diminishing quality control. Academic medical institutions should consider a proper monitoring process for videos to improve the accuracy of the published information for the patients.
