Neurologically Asymptomatic Lumbar Traumatic Dislocation With Vascular Compression in a Patient With Ankylosing Spondylitis: Case Report.

Background: Ankylosing spondylitis (AS) is associated with high rates of severe thoracolumbar fractures, in many cases with neurological deficits. It is currently a point of debate as to whether the optimal surgical treatment is posterior fixation and fusion or combined approaches. Vascular injuries in this kind of fracture are a challenging issue to solve in the management of these patients.

Spontaneus involution of meningioma. Case report and literature review.

Meningiomas are tumors of the cerebral meninges, with slow growth and usually benign, whose treatment is essentially surgery. They have progesterone receptors, and to a lesser extent estrogen, which sometimes causes them to have growth or involution linked to hormonal treatment. Its spontaneous involution is extremely rare.

Current use of Social Media in Neurosurgery in Spain.

Objective: To analyze the current situation in Spain of the use of Social Media in Neurosurgery.

Materials And Methods: We made an observational transversal study between February and March 2017, with a systematic search of the Facebook, Twitter and Youtube accounts from public and private neurosurgical units, scientific societies, peer-reviewed publications and patients groups in relation with Neurosurgical pathologies. We rank them according their popularity.

Anterior sacral meningocele presenting as intracystic bleeding.

Purpose: To report a case of anterior sacral meningocele with intralesional bleeding secondary to sacrococcygeal trauma. Likewise, there is a discussion about the physiopathology and the surgical approach to these types of lesions.

Methods: A 43-year-old man diagnosed with Marfan syndrome suffered sacrococcygeal trauma.

Treatment of chronic traumatic C7-T1 grade III spondylolisthesis with mild neurological deficit: case report.

Traumatic cervical severe spondylolisthesis is a rare and severe lesion which is typically associated with a spinal cord injury. Nevertheless, it occasionally has a pauci-symptomatic course which may delay its diagnosis. The authors report an exceptional case of a 33-year-old woman who had mild spasticity in her lower limbs and neck pain 9 months after a traffic accident.

[Trigeminal neuralgia secondary to petrous endostosis].

Arterial neurovascular compression is hypothesised to be the main cause of primary trigeminal neuralgia. Although it is the most common cause, other pathologies, such as tumours in the cerebellopontine angle, can cause trigeminal pain. We report a case of a 44-year-old female patient with right trigeminal neuralgia without satisfactory response to medical treatment.

Fluorescence-guided resection with 5-aminolevulinic Acid of subependymomas of the fourth ventricle: report of 2 cases: technical case report.

Background And Importance: The usefulness of 5-aminolevulinic acid (5-ALA) for resection of malignant astrocytomas has been established in recent years. In addition to these tumors, it has been reported that 5-ALA fluorescence could be elicited in other tumors such as intracranial and spinal meningiomas or posterior fossa and spinal cord ependymomas, resulting in improved resections. Here, we present 2 cases of subependymomas of the fourth ventricle that showed intense fluorescence after 5-ALA administration.

[Primary osteolytic intraosseous meningioma of the occipital bone].

Primary intraosseous meningiomas are considered extradural meningiomas when no dural attachment is present. Most of them arise from the cranial bones and can present either as an osteoblastic or an osteolytic lesion. Osteolytic intraosseous meningiomas are the rarest and very few cases have been reported.

[Epidural extraskeletal Ewing sarcoma. Case report and literature review].

Ewing sarcoma is a malignant tumour of the bone that sometimes presents extraskeletal involvement, with the epidural location being rare. We report the case of a 45-year-old woman with paresthesia, paresis and urinary retention. Magnetic resonance imaging showed an epidural mass from C6 to D3.
