Spinal epidural arteriovenous fistulas (SEAVFs) are rare lesions with a low risk of hemorrhage. Most patients with lumbosacral SEAVFs with hemorrhagic events will develop a spinal epidural hematoma from epidural venous pouches. To the best of our knowledge, we have reported the first case of a lumbosacral SEAVF presenting with remote intramedullary hemorrhage in the conus medullaris. ⋯ With the significant improvement of our patient after treatment of the SEAVF, we speculated that the intramedullary hemorrhage, which had occurred in the area of spinal cord edema, might have resulted from severe venous hypertension, rather than hemorrhagic infarction of the spinal cord. Careful evaluation of the angioarchitecture of SEAVFs is imperative to determine the most effective treatment modality.

Musculocontractural Ehlers-Danlos syndrome caused by pathogenic variants in CHST14 (mcEDS-CHST14) is a recently delineated connective tissue disorder characterized by multisystem congenital malformations and progressive connective tissue fragility-related manifestations. With only 2 cases of mcEDS-CHST14 containing precise information on surgical spinal correction being reported to date, there remains no consensus on treatment standards. This study describes the detailed clinical and radiologic outcomes of the third known patient with mcEDS-CHST14 who successfully underwent surgery for severe kyphoscoliosis. ⋯ On the basis of the present and 2 earlier reported cases, posterior spinal fusion may be a reasonable surgical option for severe progressive spinal deformities in patients with mcEDS-CHST14. However, careful attention is needed for possible massive blood loss from tissue fragility.

According to previous reports, pseudoaneurysms that are concomitant with a dural arteriovenous fistula (dAVF) are associated with penetrating trauma, blunt trauma, and skull fractures. Moreover, dAVFs between the inferolateral trunk of the internal carotid artery and middle cerebral vein are a rare disease manifestation. Pseudoaneurysms concomitant with dural arteriovenous fistulas (dAVF) are rare and traumatic pseudoaneurysms with dAVF typically developed slowly with less rebleeding than isolated traumatic aneurysms. ⋯ The traumatic pseudoaneurysm was completely obliterated by surgical clipping, followed by decompressive craniectomy and postoperative coma therapy with propofol. Resulting from these surgical and postoperative treatments, 56 days after the operation the patient recovered fully and did not present any neurologic deficits.

Case Report of An Anterior Thoracic Myelomeningocele - a multidisciplinary approach to surgical management.
Cervicothoracic myelomeningocele (MMC) is a rare entity with only 2 reported cases in the literature of anterior thoracic MMC. ⋯ This case highlights the unique multidisciplinary surgical management of the rare entity of anterior thoracic MMC without scoliosis correction for radiologic progression.

Resection of deep medial frontal and parietal arteriovenous malformations (AVMs) is often challenging due to a tangential angle of attack and deep, narrow working corridor. Adequate visualization of the AVM and its feeding arteries without brain retraction is of particular importance when operating in or near eloquent cortical areas, where brain manipulation could inadvertently result in neurologic deficits. The aim of this paper is to provide a step-by-step description of surgical approach and report our experience with the contralateral transfalcine approach for resection of deep-seated parasagittal AVMs. ⋯ The contralateral transfalcine approach is a useful technique in the cerebrovascular surgeon's armamentarium for management of deep-seated medial frontal, parietal, and cingulate gyrus AVMs in or around eloquent brain areas, allowing to minimize normal brain retraction and avoid associated neurologic deficits.
