Lower cranial nerve sheath tumors are relatively rare. Cases of schwannoma collision tumors have rarely been reported, with most of the reported cases describing schwannoma and meningioma collision tumors. ⋯ IgG4-RDs have a distinctive histopathologic pattern; however, their pathophysiology remains unclear. Special attention must be paid to the diagnosis of such diseases because they mimic other diseases and can be missed.

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.

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.

To characterize cranioplasty complications and costs at a population level using a longitudinal national claims database. ⋯ A high complication rate is associated with cranioplasty in the United States. Older age, large cranioplasties, and delayed cranioplasties increased complication risk overall. Among patients with emergent indications, complications were associated with delayed time to cranioplasty and autograft usage.

Ultrasound-assisted neuronavigation-guided removal of a live worm in cerebral sparganosis.
Cerebral sparganosis is a rare zoonotic infestation that often mimics glioma and metastatic tumors. ⋯ Ultrasonography was helpful in the intraoperative localization of the worm and is recommended when intraoperative magnetic resonance is not readily available.
