An isolated, unilateral fracture of the C1 lateral mass is a rare condition that has been only minimally described in the literature. Historically, these fractures have predominantly been managed conservatively with either external immobilization or traction. ⋯ After failure of conservative management, unilateral sagittal split fractures may be safely and effectively managed with unilateral open reduction and placement of a lag screw.

Spinal artery aneurysms (SAAs) are extremely rare lesions that can occur in isolation or associated with vascular malformations. Herein, we present 3 unusual cases of SAAs and discuss imaging, diagnosis, and surgical management strategies. ⋯ Spinal artery aneurysms are rare lesions. Herein, we report 3 such cases and emphasize the importance of surgical management.

Torcular meningiomas involving major dural venous sinuses are rare entities and a great challenge for neurosurgeons. The deep knowledge of the patency of occlusion of the sinuses, the extent of the occlusion and potentially new developing of extra and intracranial collateral venous drainage as compensatory venous channels, are at the base of a correct operative strategy. ⋯ We report our experience with a huge torcular meningioma with multi-venous sinus invasion and a literature review, with a special emphasis on compensatory drainage veins and surgical strategy.

The treatment of spinal metastasis consists of algorithms combining surgical and radiation modalities. Recently the concept of separation surgery followed by stereotactic radiosurgery was shown to be a safe and effective treatment to achieve local tumor control. ⋯ Minimally invasive separation surgery for spinal metastasis allows for circumferential decompression of the spinal cord and safe post-operative stereotactic radiosurgery. In addition, we demonstrated the efficacy of intra-operative navigation in guiding the resection.
