Correlation of Intraoperative Neurophysiological Parameters and Outcomes in Patients with Intramedullary Tumors.

Introduction: Intramedullary spinal cord tumors (IMSCT) account for about 2%-4% of all central nervous system tumors. Surgical resection is the main treatment step, but might cause damage to functional tissues. Intraoperative neuromonitoring (IONM) is an adopted measure to decrease surgical complications.

Endoscopic resection of sellar and suprasellar epidermoid cyst: report of two cases and review of literature.

Introduction: Epidermoid cysts (EC) are lesions developing from neuroectodermal epithelial cells. They represent 1-2% of all intracranial tumors and are usually found in cerebellopontine angle and parasellar regions. To the best of our knowledge, only 27 cases have been reported of EC in sellar and suprasellar region.

Lumbar disc herniation with contralateral radiculopathy: a systematic review on pathophysiology and surgical strategies.

Lumbar disc herniation (LDH) is a relatively common pathology usually presenting with unilateral radiculopathy ipsilateral to the disc herniation. Some patients can present with contralateral radicular symptoms. The objective of this article is to review the current literature on lumbar disc herniations with contralateral radiculopathy regarding its pathophysiology and surgical strategies.

Improvement of Hemichorea Following Surgical Resection of a Putaminal Cavernous Angioma: Case Report and Review of Literature.

Background: Hemichorea may point to a structural lesion in the contralateral basal ganglia with a large list of possible causes. Cavernous angioma may be rarely a possible cause for acute appearance of this movement disorder.

Case Description: We present a rare case of a 32-year-old female patient with hemichorea caused by a cavernoma (or cavernous angioma) in the contralateral insula and putamen with complete improvement of symptoms with surgical resection of the lesion.

Radiologic Features of Spontaneous Regression of Vestibular Schwannomas.

Background: Vestibular schwannoma (VS) is the most common benign tumor originating in the cerebellopontine angle. In most cases, tumors tend to grow and deserve proper treatment. Sometimes they stabilize, and rarely they decrease in size spontaneously.

5-Aminolevulinic acid fluorescence-guided surgery for spinal cord melanoma metastasis: a technical note.

Background: According to our research, just few studies described 5-Aminolevulinic acid (5-ALA) use for spinal injuries resection. 5-ALA is known to be especially useful in certain spinal tumor entities such as meningiomas, ependymomas, hemangiopericytomas, and metastasis of central nervous system primary tumors. In contrast, 5-ALA has limited value in other histopathological tumoral entities, as neurinomas and carcinoma metastasis.

Alternative option for osteogenesis imperfecta and trigeminal neuralgia.

Osteogenesis imperfecta (OI) is a bone disorder that can lead to skull base deformities such as basilar invagination, which can cause compression of cranial nerves, including the trigeminal nerve. Trigeminal neuralgia in such cases remains a challenge, given distorted anatomy and deformities. We present an alternative option, consisting in cannulation of the foramen ovale and classical percutaneous treatment.

Giant scalp arteriovenous malformation.

Arteriovenous malformations (AVMs) of the scalp are rare lesions. The clinical picture presents with complaints of increased scalp, scalp disfigurement, pain and neurological symptoms. Its origin can be congenital or traumatic.

Spontaneous intracranial epidural hematoma during rivaroxaban treatment.

According to our research, this is the first case described in the literature of spontaneous intracranial epidural hematoma secondary to the use of Xareltor. Spontaneous intracranial epidural hematomas are rarely described in the literature. They are associated with infectious diseases of the skull, coagulation disorders, vascular malformations of the dura mater and metastasis to the skull.

Dorsal Arachnoid Web and Scalpel Sign: A Diagnostic Imaging Entity.

Material And Methods: A case of 60-year-old woman with idiopathic syringomyelia and progressive myelopathy by dorsal arachnoid web is discussed. One focal indentation along the dorsal surface of the spinal cord at the T3 vertebral body level revealed the scalpel sign, a radiologic entity diagnostic of a dorsal thoracic arachnoid web.

Results: T2-T3 laminectomy for the resection of dorsal arachnoid band was performed.

Association between primary headaches and depression in young adults in southern Brazil.

Objective: To verify the association between depression and headache in young adults, as well as to identify the features of headache associated with depression and the influence of this mood disorder on headache-related disability.

Methods: A cross-sectional study with self-administered questionnaires about headache and depression was conducted at the Universidade de Caxias do Sul. Beck Depression Inventory (BDI) and Migraine Disability Assessment (MIDAS) were used to evaluate depressive symptoms and headache-related disability, respectively.

Depression Subscale of the Hospital Anxiety and Depression Scale applied preoperatively in spinal surgery.

Objective: To evaluate the accuracy of the Depression Subscale of Hospital Anxiety and Depression Scale (HADS-D) in spine surgery, comparing it to Beck Depression Inventory (BDI).

Methods: In a cross-sectional study, the HADS-D and the BDI were applied to patients undergoing spine surgery for lumbar (n=139) or cervical spondylosis (n=17). Spearman correlation tests for HADS-D and BDI were applied.
