[Cervical paraspinal chordoma, a condition we should know. A case report].

Chordoma is a rare, slow-growing tumour arising from remnants of the notochord. It is most often located in the base of the skull and the sacrococcygeal region, being located in the cervical region in only 6% of cases. A rare case is presented of a left para-spinal chordoma, of which less than 10 cases have been reported in literature.

Unprotected carotid artery stenting in symptomatic elderly patients: a single-center experience.

Background And Purpose: Surgery is known to have fewer adverse events in patients aged >75 years with carotid stenosis, but some are not candidates due to comorbidity. Stenting using protection devices is the most accepted endovascular technique. Our aim is to show the safety and efficacy of carotid stenting without any protection device in these patients.

Appropriateness of lumbar spine magnetic resonance imaging in Spain.

Objectives: To determine the minimum percentage of lumbar spine magnetic resonance imaging (LSMRI) which are inappropriately prescribed in routine practice.

Methods: LSMRI performed prospectively on 602 patients in 12 Radiology Services across 6 regions in Spain, were classified as "appropriate", "uncertain" or "inappropriate" based on the indication criteria established by the National Institute for Clinical Excellence, the American College of Physicians and Radiology, and current evidence-based clinical guidelines. Studies on patients reporting at least one "red flag" were classified as "appropriate".

[Lemierre syndrome: thrombosis of the cavernous sinus and internal carotid artery occlusion secondary to acute sphenoid sinusitis].

Lemierre syndrome (LS) typically consists of a septic thrombophlebitis of the internal jugular vein caused by Fusobacterium necrophorum. We present an unusual variant of LS with cavernous sinus thrombosis and occlusion of the ipsilateral internal carotid artery secondary to sphenoid sinusitis caused by Streptococcus viridans.

Tympanic paraganglioma with extension into the Eustachian tube and nasopharynx: a case report.

Tympanic paragangliomas usually present as a vascular middle ear mass, with the most common presenting symptoms being pulsatile tinnitus and hearing loss. We report an unusual case of a recurrent tympanic paraganglioma extending along the Eustachian tube and nasopharynx, presenting with recurrent epistaxis.

Treatment of dural arteriovenous fistulas presenting as pulsatile tinnitus.

Objective: To describe the clinical picture and treatment of dural arteriovenous fistulas (DAVFs) presenting as pulsatile subjective tinnitus.

Study Design: Review of prospectively collected data.

Setting: Academic referral center.
