Review Case Reports
Coexistence of extra-axial cavernous malformation and cerebellar developmental venous anomaly in the cerebellopontine angle.
The coexistence of cavernous malformations (CMs) and developmental venous anomalies (DVAs) in the cerebellopontine angle (CPA) is exceedingly rare. To the authors' knowledge, only one case of CPA CM with concurrence of a neighboring DVA has been reported to date. ⋯ CMs should be considered in the differential diagnosis of any extra-axial hemorrhagic mass, especially with a DVA in the proximity. The coexistence of CM and DVA in CPA, although maybe just a coincidence, suggests the possibility of a new subtype of extra-axial CPA CM secondary to a preexisting DVA. A long-term follow-up is justified in discovering the potential mechanism and biology of such uncommon vascular malformations.

To review retrospectively experience with stent-assisted coiling of ophthalmic segment internal carotid artery (ICA) aneurysms to report outcome data and identify the rate of associated visual complications. ⋯ Stent-assisted embolization of ophthalmic segment ICA aneurysms is technically achievable and in our series did not appear to result in increased visual complications compared with coil embolization alone or surgical treatment.

Pediatric spinal arteriovenous malformations (AVMs) are rare and complex lesions to treat. There are few reports of the endovascular and microsurgical treatment of these lesions in the pediatric population, and the treatment outcomes of these patients are not well described. The aim of this study was the clinical and radiographic outcomes of spinal AVMs in pediatric patients treated via endovascular and microsurgical modalities. ⋯ Pediatric spinal AVMs require complex combined microsurgical and endovascular techniques to achieve favorable outcomes.

Case Reports
Cervical spinal brucellosis with epidural abscess causing neurologic deficit with negative serologic tests.
Here we present a case of cervical spinal epidural abscess causing neurologic deficits despite negative serologic tests. ⋯ It is important for clinicians to consider brucellar cervical spondylodiscitis when an epidural abscess is identified in a patient with a history of potential exposure. We recommend both blood and tissue cultures for diagnosis when serologic tests are negative.

The purpose of the present study is to assess the possibility of disc regeneration by treatment with adipose-derived stem cells (ADSCs) in a rabbit model of degenerative disc disease, and to evaluate the efficacy of a percutaneous technique for constructing a model of degenerative disc disease in rabbits. ⋯ These results suggest that the injection of ADSCs into injured lumbar discs could be an effective treatment for degenerative disc disease by promoting the cartilage regeneration.
