Primary gliosarcoma is a rare form of malignant central nervous system tumor, with limited understanding regarding its prognostic determinants and effective therapeutic interventions. ⋯ The present study's findings suggest that optimal management of primary gliosarcoma entails maximal safe resection, combined with adjuvant radiotherapy and chemotherapy with temozolomide, followed by salvage therapy in case of recurrence. However, the risk of metastases should be carefully monitored during the treatment course.

While endoscopic approaches to the spine have become increasingly utilized for spinal degenerative disease, there is a paucity of literature regarding the role of endoscopic approaches in spinal oncology.1 The endoscopic approach offers patients lower risk of wound infection, wound dehiscence, and postoperative hematoma when compared with an open approach.1 In many spinal oncology patients, an endoscopic approach allows for prompt postoperative radiation when compared with an open approach.2 Both the lower complication profile and decreased time to postoperative radiation highlight the importance of considering an endoscopic approach to metastatic spinal tumors. We present a case of a patient with a metastatic carcinoma to the thoracic spine resected via an endoscopic approach. The patient's tumor was first treated with endovascular embolization, followed by endoscopic hemilaminectomy, foraminotomy, and tumor resection. ⋯ Per institutional guidelines, the current case Video 1 did not classify as human subject research or require institutional review board review. In the Video 1, particular focus is placed on the surgical techniques involved in the endoscopic approach for resection a spinal metastatic tumor. With the increasing utilization of endoscopic approaches to the spine, the described technique for resection of spinal metastatic lesions will become increasingly relevant to spinal oncology surgeons.

To evaluate the accuracy of stereotactic coordinates to target the ansa lenticularis (AL) using 2 surgical planning methods, the conventional millimeter method (MM) and the normalized Tenths method (TM), assessed through individualized probabilistic tractography. ⋯ TM surpasses MM in identifying the structural connectivity between the AL and predefined ROIs, underscoring the advantages of coordinate normalization. However, variations in AC-PC line lengths and Euclidean distances between methods could lead to inaccuracies in the coordinate settings, potentially affecting the precision of structural connectivity and the efficacy of therapeutic outcomes.
