Aneurysms of the anterior choroidal artery are uncommon, and distal anterior choroidal artery aneurysms are even rarer, with only 34 cases reported in the medical literature. These lesions have been most commonly reported in association with moyamoya disease or arteriovenous malformations. Most published experience with these aneurysms involves open surgical approaches. Reports of endovascular treatment have been in patients with lesions distal to the plexal point and have employed vessel occlusion with liquid embolic agents in preference to coil embolization. ⋯ Endovascular coil embolization for distal anterior choroidal artery aneurysms is technically feasible and may be preferable to embolization with liquid embolic agents for lesions proximal to the plexal point. This case illustrates the utility of provocative testing and efficacy of endovascular coil embolization for lesions in this unique location.

To explore risk factors affecting surgical results of Hirayama disease. ⋯ Age of patient, duration of the disease, physiologic reflex, and pathologic reflex are the main risk factors affecting surgical results of Hirayama disease. Receiver operating characteristic analysis shows that good reference value was obtained for the risk factors.

Carcinoid tumors are neuroendocrine neoplasms derived from enterochromaffin cells. Central nervous system involvement is rare. The reported cases include metastases to brain or spinal cord, and primary skeletal or extradural disease resulting in compressive myeloradiculopathy. There are 2 previously reported cases of primary intradural extramedullary carcinoid tumor, presenting with compressive symptoms. We report the first case of primary incidental intradural extramedullary carcinoid tumor. ⋯ To our knowledge, this is the first reported case of incidental primary intradural spinal carcinoid tumor. Even though intradural spinal carcinoid tumors are exceedingly rare, they should be included in the differential diagnosis of enhancing intradural lesions.

We report on a patient with 2 Mendelian diseases-symptomatic multiple familial cerebral cavernous malformations (FCCMs) and Wilson disease. Genetic analysis revealed single nucleotide polymorphisms in genes CCM2 and CCM3, associated with cavernous malformations, and homozygote mutation in the ATP7B gene, responsible for Wilson disease. ⋯ In recent years there has been an increasing amount of publications linking FCCMs with other pathology, predominantly with extracranial and intracranial mesenchymal anomalies. The present study is the description of an unusual association between 2 independent hereditary diseases of confirmed genetic origin-a combination that has not been described previously.

There is no standardized approach to assess and manage perioperative neurologic deficit (PND) in patients undergoing spinal surgery. This survey aimed to evaluate the awareness and usage of clinical practice guidelines (CPGs) as well as investigate how surgeons performing spine surgeries feel about and manage PND and how they perceive the value of developing CPGs for the management of PND. ⋯ Most respondents are aware and routinely use CPGs in their practice. Most surgeons performing spine surgeries reported not feeling comfortable managing PND. However, they highly value the creation and are likely to use CPGs in its management.
