Tumours of the pineal region are rare in adulthood, accounting for approximately 1% of intracranial neoplasms in this age range. Because of their rarity, it has proven to be difficult to establish the optimal therapy. Furthermore, microsurgical total resection in this eloquent location is associated with not low rates of morbidity. We described two patients diagnosed of papillary tumours of the pineal region (PTPR) by stereotactic biopsy and referred for gamma knife radiosurgery after shunting for hydrocephalus...

BACKGROUND: Superior laryngeal neuralgia (SLN) is a relatively rare disorder that is characterized by neck pain. There are only a few reported cases and treatment options for SLN to date. OBJECTIVE: In this study, we reported 3 patients with SLN who were treated with gamma knife radiosurgery (GKRS) at the time of diagnosis. METHODS: For all 3 patients, GKRS was administered using a 4-mm collimator to deliver a single shot of 80 Gy of radiation (the 100% isodose line)...

OBJETIVE: The aim of this study was to investigate the anatomy of the superior cluneal nerves more proximal to the posterior layer of the thoracolumbar fascia. METHODS: Twelve sides of six fresh-frozen cadavers were used. The age at death ranged from 54 to 88 years. After a transverse skin incision 10 mm above the iliac crest, the superior cluneal nerves were detected by blunt dissection and traced back to the dorsal root ganglia. The diameter of the nerves from L1 to L3 was measured...

The description of paraplegia is considered a milestone in the history of neurology. The Egyptians provided excellent descriptions of spinal cord injuries, the Bible has several references to paraplegia, and, more recently, the pioneers of neurology described the classic syndromes related to spinal injuries and paraplegia. Here, we describe an ancient observation by the Assyrian people of paraplegia in an animal. In ancient Assyria, lion hunting was a ritualized activity conducted for political and religious purposes...

Lumbar total disc replacement (LTDR) is considered for the treatment of lumbar degenerative disc disease with the hope that by preserving motion the long-term fusion complication of adjacent segment disease can be avoided. The complications of LTDR can be divided into approach-related and long-term complications. Very little has been described about the complications and treatment for complications more than 10 years after the device has been implanted. Here we describe a tranforaminal endoscopic discectomy procedure for a patient presenting with foot drop twelve years after a L5-S1 total disc replacement...

OBJECTIVE: Vascular and osteological parameters, such as the heights of the carotid bifurcation and distal end of the plaque, are important preoperative considerations for patients undergoing carotid stenosis procedures such as carotid endarterectomy. However, for patients with contrast contraindications such as allergies or nephropathies, three-dimensional computed tomography angiography (3D-CTA) is unavailable, and preoperative evaluation remains challenging. In the present study, we aimed to develop a preoperative simulation for use in patients with contrast-contraindicated carotid stenosis...

OBJECTIVE: To evaluate the effectiveness of micro-clamping stent-retriever thrombectomy (MSRT) in acute ischemic stroke patients with intracranial large vessel embolism (ILVE), and compare the same with conventional stent-retriever thrombectomy (CSRT). MATERIALS AND METHODS: We retrospectively evaluated a total of 108 ILVE patients treated by MSRT (n=52) and CSRT (n=56) from the two participating institutions between January 2016 and November 2017. The rates of successful (mTICI 2b or 3) and complete reperfusion (mTICI 3), time from guide catheter placement to reperfusion, rates of first-pass success, and the number of passes for reperfusion were compared between the MSRT and CSRT groups...

This is a case report about a 34-year-old man with hereditary multiple exostoses presented with gradual tetraparesis. Neuroimaging evaluation revealed an important posterior spinal cord compression by a C3 bony formation. Following posterior microsurgical decompression, the patient recovered nearly completely. Histopathological examination of the intraspinal lesion confirmed the diagnosis of benign osteochondroma. The patient returned to a normal life without evidence of recurrence at 2-year follow-up.

BACKGROUND: Lumbar herniated disc is a "preference-sensitive" condition, in which the optimal treatment choice is crucially dependent on an informed patient's goals and values. Little is known about decisional conflict, defined as an individual's level of uncertainty regarding a decision, in patients considering treatment for lumbar herniated discs. Our work aims to identify factors associated with decisional conflict and areas for improved shared decision-making. METHODS: We prospectively surveyed patients seeking treatment for a lumbar herniated disc at L4-L5 and/or L5-S1 with a physician at the UCLA Spine Center...

BACKGROUND: Lumbar disc herniation (LDH) is a common degenerative disease of the lumbar spine with a prevalence of 1-3% in population studies according to some authors. In 10% of patients there is a fragment migrated cranially in the Macnab's "hidden zone". In selected cases, this fragment can be removed with a translaminar approach that has been described in 1998. Aim of our work is to provide a detailed description of the technical advantages and pitfalls of such approach reviewing a consecutive series of patients...

BACKGROUND: Stereotactic radiosurgery (SRS) is used to manage patients with Cushing's disease (CD) who have failed surgical/medical management. As many patients with recurrent/persistent CD lack an identifiable adenoma on neuro-imaging, whole-sellar SRS has been increasingly employed. We therefore sought to define the outcomes of patients undergoing whole-sellar SRS. METHODS: An international, multicenter, retrospective cohort-design was used to define clinical/endocrine outcomes for patients undergoing whole-sellar SRS for CD...
