Angiosarcomas are rare malignant tumors of endothelial origin. Nearly one half of all angiosarcomas occur in the head and neck. Temporal bone angiosarcomas are extremely uncommon. We present a case of temporal bone angiosarcoma and a review of the relevant data. ⋯ Angiosarcoma of the temporal bone is extremely uncommon. In the present case report, we explored a relationship between trauma and angiosarcoma of the temporal bone. We reviewed the reported data regarding the pathogenesis, diagnosis, treatment, radiologic findings, and histologic characteristics of angiosarcoma of the temporal bone.

Three new 0.071-inch and 0.072-inch aspiration catheters have been introduced for stroke thrombectomy. Their comparative efficacy has not been clinically evaluated. ⋯ In comparing the newest large bore aspiration catheters, similar angiographic efficacy is achieved.

Vascular malformations of the spinal cord are a rare and complex clinical entity and can lead to severe morbidity with progressive spinal cord symptoms if not treated properly. In early stages, the disease is characterized by slowly progressive, nonspecific symptoms, such as gait disturbance, paresthesia, diffuse sensory symptoms, and radicular pain; in the late stages, bowel and bladder incontinence, erectile dysfunction, and urinary retention may develop. In recent decades, understanding and treatment of spinal vascular malformations have improved with the evolution of diagnostic tools and treatment modalities; however, it is still difficult to manage these cases because of the complexity of the pathology. The aims of this study were to present the long-term outcomes of our patients and to discuss the optimal management strategies. ⋯ Both endovascular and surgical treatment of spinal vascular malformations resulted in significant long-term recovery from myelopathic symptoms and improvement in quality of life for most patients.

YouTube has rapidly become one of the most widely accessed educational platforms of our time. Over 1 billion hours of YouTube content are viewed every day, including neurosurgical videos. To date, there has never been a qualitative analysis of neurosurgical content on YouTube. ⋯ YouTube is a frequently viewed but biased source for neurosurgical information. Advertisements are frequently disguised as educational material, and few videos provide references or sources for their information.

Cavernous hemangiomas arising in the extraaxial space are rarely encountered, often mimicking other more common pathologies. Furthermore, multiple coexisting lesions and posterior fossa involvement are scarcely reported. Herein, we present the case of a patient with concurrent frontal bone and posterior fossa extraaxial cavernous hemangiomas. We also review the challenges associated with the diagnosis and management of these entities. ⋯ Extraaxial cavernous hemangiomas are uncommon clinical entities that are challenging to distinguish from other diseases. If intraoperative complications can be avoided, treatment with surgical resection often offers excellent patient outcomes.
