Segmental arterial mediolysis is a rare disease characterized by idiopathic noninflammatory vasculopathy involving small to medium arteries. Here, we report a case of ruptured cerebral and abdominal aneurysms, which were successfully treated using emergency endovascular coil embolization. ⋯ It is extremely rare for a subarachnoid and an abdominal hemorrhage to occur simultaneously during hospitalization. Here, owing to the vulnerability of the unaffected vertebral artery during the initial procedure, segmental arterial mediolysis was diagnosed.

Transpedicular Intrabody Cage Insertion with Posterior Spine Stabilization in Kümmell Disease: Report of 2 Cases.
Kümmell disease has been treated with multiple surgical approaches, as described in the literature. However, there are few reports describing the technique of transpedicular intrabody cage insertion to enhance bony fusion and maintain the height of the vertebral body. We describe the technique of transpedicular intrabody cage insertion with posterolateral fusion in patients with Kümmell disease. ⋯ Transpedicular intrabody cage insertion is a safe and effective procedure for treating vertebral osteonecrosis to achieve bone formation at the site of vertebral osteonecrosis and to maintain body height.

Dermoid cysts are rare tumors usually seen in the midline structure of the brain but rarely arise in the petrous apex and cavernous sinus. There have been very few reports of dermoid cysts arising in the infratemporal fossa, with scarce anatomic descriptions. Here we report the case of a patient with a dermoid cyst in the left infratemporal fossa. ⋯ Dermoid cysts in the infratemporal fossa are extremely rare. However, tumor resections can be performed safely and efficaciously using anatomically detailed preoperative planning.

Straight Fenestrated Clips in Surgical Management of Internal Carotid Artery Aneurysms: Technical Note.
Using angled fenestrated clips for posteromedially projecting internal carotid artery (ICA) aneurysms may allow the surgeon to simultaneously obliterate the aneurysmal neck and preserve the branching artery by applying the blade of the clip parallel to the ICA. However, using these clips when the aneurysm neck involves the branching artery may have a risk of branching artery stenosis, occlusion, or incomplete obliteration of the aneurysm. ⋯ When using angled fenestrated clips is unsuitable because of a risk of branching artery stenosis, occlusion, or incomplete obliteration of the aneurysm, using multiple straight fenestrated clips may be a useful alternative.

The aim of this study was to investigate the anatomy of the superior cluneal nerves more proximal to the posterior layer of the thoracolumbar fascia. ⋯ The results of this study could help to elucidate the anatomy of the superior cluneal nerves and help avoid complications during surgical approaches to the lumbar spine.
