Spontaneous cervical epidural hematoma (SCEH), which is a rare disease, is manifested as by a sudden quadriplegia or paraplegia and other neurological deficits. SCEH can compress the spinal cord resulting in its clinical manifestations. The reported etiological risk factors are anticoagulants, coagulopathies, vascular malformations, infections, and herniated discs. Read More

Intracranial dural arteriovenous fistula (DAVF) with perimedullary venous drainage may cause brainstem swelling and represent a diagnostic challenge. A 66-year-old man presented to the emergency room with recurrent vertigo, minimal truncal ataxia with a wide-based gait, and a slightly impaired tandem gait. Brain magnetic resonance imaging (MRI) revealed a hyperintense lesion in the left pontomedullary area on T2-weighted images (T2WIs) with partial gadolinium enhancement, but without increased signals on diffusion-weighted images.

Spinal cord infarction is very rare condition and usually occurs in the thoracic region of the spine. The etiology is often unknown and patophysiology can be diverse. The stroke may occur while performing a surgical procedure, but it is also found in vascular diseases, for example dissecting aneurysms, vasculitis and vascular malformations. Read More

The literature has long attempted distinct classifications of arteriovenous fistulae and arteriovenous malformations of the spine.1-3 It is worth noting that lesions can become more complex during recurrence and may not adhere to traditional definitions. In these cases, recognizing the principles of pathology and pathophysiology can guide management and treatment. Read More

Vascular disorders of the spine are more rare than cerebral vascular entities but can result in significant morbidity. These lesions frequently demonstrate distinguishing characteristics by imaging that are imperative for the radiologist to recognize to properly guide diagnosis and treatment. We review distinguishing imaging characteristics for spinal vascular malformations, spinal emergencies, and spinal vascular masses. Read More

Rationale: Spontaneous intramedullary spinal cord hemorrhage (hematomyelia) is a rare disease and most cases have specific etiologies such as cavernous malformations and tumor. Most reported cases are about surgical treatment of intramedullary spinal cord hemorrhage, but there are no reports of rehabilitation effectiveness reported.

Background Vascular lesions represent a rare subset of intramedullary spinal cord pathology and consist of cavernous malformations (CM), hemangioblastomas, and arteriovenous malformations (AVM).

Section of Neurosurgery, Department of Neurosciences (DINOGMI), San Martino University Hospital, University of Genoa, Genoa, Italy.

Objective: Dorsal intradural arteriovenous fistulas (AVFs) consist of a direct connection between a radicular feeding artery and the coronal venous plexus; this direct connection leads to arterialization of the venous plexus, venous congestion, and myelopathy. Controversy still exists regarding the best treatment modality of spinal dural AVFs. Surgical disconnection of spinal dural AVFs is a straightforward procedure with a high success rate and virtually no risk of recurrence or incomplete treatment. Read More

Background And Importance: Advances in minimally invasive (MIS) and mini-open surgical approaches have led to reductions in perioperative morbidity without compromising rates of resection of non-degenerative intradural spinal pathologies. Whether these approaches may be adapted for the surgical resection for intramedullary vascular malformations - such as cavernous malformations (CMs) - has yet to be reported. The authors describe a mini-open transspinous approach to resect a ruptured intramedullary CM of the conus medullaris. Read More

Purpose: The diagnosis of spinal dural arteriovenous fistula (SDAVF) is difficult and often delayed because clinical features are often nonspecific. We assessed the motor function electrophysiologically in patients with SDAVF.

Methods: Motor-evoked potentials after transcranial magnetic stimulation and compound muscle action potentials and F-waves after electrical stimulation in the ulnar and tibial nerves were measured from the abductor hallucis (AH) muscles in 14 patients with SDAVF (SDAVF group), 12 patients with compressive thoracic myelopathy (CTM group), and 16 normal subjects (control group).

The topographical distribution of dural arteriovenous fistulas (DAVFs) was analyzed based on the embryological anatomy of the dural membrane. Sixty-six consecutive cases of intracranial and spinal DAVFs were analyzed based on the angiography, and each shunt point was identified according to the embryological bony structures. The area of dural membranes was categorized into three different groups: a ventral group located on the endochondral bone (VE group), a dorsal group on the membranous bone (DM group), and a falcotentorial group (FT group) in the falx cerebri, tentorium cerebelli, falx cerebelli, and diaphragma sellae.

Department of Neurosurgery, Democritus University of Thrace Medical School, Alexandroupolis, Greece.

Objective: Spinal arteriovenous malformations (AVM) manifest in the pediatric population very differently from the ones in adulthood. Despite that fact, the treatment strategy is quite the same, which provokes a question - whether some of the therapies have an advantage and if so, in which age group.

Methods: For this reason, the authors searched the world literature between 1989 and 2018 for spinal AVM in children and further categorized the studies into two age groups: < 12 and ≥12. Read More

Background And Purpose: Spinal cord hemorrhages are rare conditions that can be classified based on the primary location of bleeding into intramedullary (hematomyelia), subarachnoid hemorrhage (SAH), subdural hemorrhage, and epidural hemorrhage. We conducted a literature review to better understand the presenting symptoms, etiology, diagnosis, and treatment of spinal cord hemorrhages.

Methods: We performed a literature search using PubMed with the key words spinal hemorrhage, hematomyelia, spinal subarachnoid hemorrhage, spinal subdural hematoma, and spinal epidural hematoma RESULTS: Most commonly, spinal hematomas present with acute onset of pain and myelopathy but a more insidious course also may occur.

The radiological signs of intracranial dural arteriovenous fistulas (ICDAVFs) are heterogenous. While it is commonly accepted that hyper intense T2 wedge magnetic resonance imaging of the brainstem and cervical cord mainly concern gliomas, it is so far uncommon and probably unknown that ICDAVFs can imitate similar radiological pattern, especially with gadolinium contrast enhancement and cord enlargement. Thus the angiography is poorly documented in the diagnostic workup. Read More

Spinal dural arteriovenous fistulas (AVFs), being the most commonly encountered spinal vascular malformations, result in considerable morbidity with progressive spinal cord symptoms. A selective spinal digital subtraction angiography (DSA) is needed to confirm the diagnosis, to better evaluate the fine vascular structures and to plan therapy. With the introduction of three-dimensional rotational angiography (3D-RA), the information available for the treating physician has vastly increased. Read More
