Presentation of clinical cases involving successful anterior stabilization of the C1-C2 segment in patients with invaginated C2 odontoid process and Chiari malformation type I. ⋯ Anterior decompression followed by anterior stabilization of the C1-C2 segment is a novel and promising approach to treating Chiari malformation type I in association with C2 odontoid process invagination.

Intracranial arterial atherosclerosis represents a common cause of stroke. Despite aggressive and optimal medical management, many patients will unfortunately suffer additional cerebrovascular events. The role of endovascular intervention for intracranial atherosclerotic disease continues to be uncertain, particularly in regard to extensive, symptomatic stenosis. ⋯ This case illustrates that a long coronary stent might be successfully used to manage extensive intracranial lesions. We also review the efficacy of using 1 very long stent versus multiple overlapping stents, with reference to the coronary angiography literature.

To analyze outcomes of patients surgically treated for calcified spinal meningiomas and to determine factors associated with surgical morbidity. ⋯ The univariate analysis confirms that the degree of calcification affects the outcome, because extensive tumor calcification is associated with an increased surgical morbidity probably.

Aneurysms of the external carotid artery represent approximately 2% of cervical carotid aneurysms, with the majority being traumatic pseudoaneurysms. Given the paucity of literature available for guidance, the diagnosis, treatment, and follow-up of such lesions are completely individualized. ⋯ To the best of our knowledge, this is the second reported case of a true aneurysm of the occipital artery in a patient with no history of trauma. The clinical examination, diagnosis, and treatment are discussed and the literature is reviewed for previously reported cases.

Perimesencephalic Nonaneurysmal Subarachnoid Hemorrhage after Clipping of an Unruptured Aneurysm: Case Report.
Perimesencephalic nonaneurysmal subarachnoid hemorrhage (PNSAH) is a benign form of subarachnoid hemorrhage with an excellent clinical outcome. The cause of PNSAH remains unknown. We report a case of PNSAH in a patient with a history of clipping of an unruptured aneurysm. PNSAH after clipping of an unruptured aneurysm is extremely rare. ⋯ On the basis of this case report, clinicians should consider the possibility of PNSAH in a patient who had an unruptured aneurysm previously treated with clipping. Nevertheless, diagnostic workup can be more important than keeping in mind that a subarachnoid hemorrhage might be a PNSAH.
