OBJECT The purpose of this study was to describe complications associated with the endonasal, transsphenoidal approach for treatment adrenocorticotropic hormone (ACTH)-positive staining tumors (Cushing's disease [CD] and silent corticotroph adenomas [SCAs]) performed by 1 surgeon at a high-volume academic medical center. METHODS Medical records from Brigham Women's Hospital were retrospectively reviewed. Selected 82 patients CD who during April 2008-April 2014 had consecutively undergone...
Background: Intracranial teratomas represent a rare subset of neoplasms characterized by tissues derived from multiple germ layers within the cranial cavity. These tumors, originating primordial cells, exhibit diverse clinical presentations and histopathological features. While predominantly located along midline axis, including suprasellar cistern pineal region, they can also manifest in less common areas such as ventricles hypothalamic regions. Histopathologically, are classified mature,...
Introduction: Numerical classification systems for the internal carotid artery (ICA) are available, but modifications have added confusion to numerical systems. Furthermore, previous classifications may not be applicable uniformly microsurgical and endoscopic procedures. The purpose of this study was develop a clinically useful system.Materials Methods: We performed cadaver dissections ICA in 5 heads (10 sides) evaluated 648 arteries with computed tomography angiography. identified specific...
The authors provide a review of true aneurysms the posterior communicating artery (PCoA). Three cases admitted in our hospital are presented and discussed as follows.First patient is 51-year-old female presenting with Fisher II, Hunt-Hess III (headache confusion) subarachnoid hemorrhage (SAH) from ruptured aneurysm right PCoA. She underwent successful ipsilateral pterional craniotomy for clipping was discharged on postoperative day 4 without neurological deficit. Second 53-year-old I,...
Intraventricular and extraventricular central neurocytomas (CN) are equally frequent among 20-40-year-old men women. However, sellar suprasellar CN extremely rare, with only 12 reported cases.The authors report the case of a Brazilian 27-year-old man who presented progressive vision loss during last 4 years serious bilateral keratoconus. We also review epidemiological, clinical, radiological, pathological, treatment features cases. The patient developed left amaurosis right temporal...
Correlate the middle cerebral artery bifurcation aneurysm morphology with pre-operative and intra-operative risk of rupture.Forty patients 46 aneurysms were treated microsurgically by same surgeon. Aneurysms classified according to shape Fisher test was applied analyze effect on rupture.Pre-operative ruptures observed in 8/46 (17.4%) 14/46 (30.4%) respectively. Thirty-two cases (69.6%) had no symptoms postoperatively, modified Rankin score (MRS) 0; 6.5% MRS 1 (no significant disability); 13%...
Posterior fossa strokes account for 20% of ischemic and present significant diagnostic therapeutic challenges due to their anatomical complexity.The vertebral artery is crucial the blood supply posterior cerebellum, making its stenosis a critical risk factor recurrent neurological deficits.Objective: To report rare case stent fracture after angioplasty in an elderly patient with stroke.Case description: An 86-year-old man hypertension presented sudden dysarthria, right labial commissure...
Abstract Background Spinal epidural abscess is a rare but serious condition that can cause spinal cord compression and neurological deficits. Case Description Methods The article reports case of 31-year-old patient who presented with an infectious cellulitis in the left hand, which progressed to abscess. diagnosis was confirmed by clinical examination magnetic resonance imaging. Treatment involved laminectomy, after had complete recovery This report literature review. Patient data images...
Background: The Klippel–Feil syndrome (KFS) is a rare congenital anomaly characterized by the fusion of cervical vertebrae, which may be associated with other malformations, such as dermoid tumors and teratoma. Some theories explain embryology these associations. Another condition that present dermal sinus (DS), communication between intracranial subcutaneous tissue, predisposing infections. This case report aims to describe an association three pathologies well correlate them from...
The present case report aims to describe a surgical approach procedure for an orbital reconstruction in patient with craniofacial fibrous dysplasia, planned virtual mirroring and simulation using 3D-printed realistic model. was followed up by the neurosurgery oral maxillofacial surgery teams diagnosed monostotic dysplasia right frontal bone, affecting roof. Our team performed planning through non-affected side. then access bone roof titanium plate. Both monitored patient, who presented no...
The objective of this article is to report a case silicone oil migration into intraocular packing in cases retinal detachment, while reviewing the existing literature on various mechanisms and locations migration. However, it important highlight that use material not free from complications.
oncogenic miR-21 in neurospheres and attached cells a glioblastoma cell line culture (U343-MG).The methods included staining with Trypan blue to verify viability real time PCR quantify the expression of microRNAs after exposure treatments.We observed that miR-16 was more highly expressed than 48h treatment temozolomide, compared treated temozolomide at 0 h (30 min treatment); 48 this microRNA association ionizing radiation.We concluded were differentially when comparing different types...
Intramedullary primitive neuroectodermal tumors (PNETs) are found rarely in the cervical region, with only five such cases described literature. The available literature contains one report regarding cervicomedullary junction PNET.The authors present a case of 45-year-old male patient who had undergone urgent hospitalization owing to progressive tetraparesis and subtle impairment respiratory function. He underwent magnetic resonance imaging, which showed an extensive enhancing intramedullary...
The use of 3D printing in treatment cranial and spinal pathologies has given rise to investigation its utility as practical anatomically precise methods. In this we review three-dimensional molds for surgical planning pathological comprehension the neurosurgical field; also, it's affordable/price comparability other synthetic competitors market. Case report based on retrospective analysis medical record complementary exams patient associated with a literature indexed databases MEDLINE,...
Introduction Cardiac surgery with cardiopulmonary bypass (CPB) is a recognized trigger of systemic inflammatory response, usually related to postoperative acute lung injury (ALI).As an attempt dampen steroids have been perioperatively administered patients.Macrophage migration inhibitory factor (MIF), regulator the endotoxin receptor, implicated in pathogenesis ALI.We previously detected peak circulating levels MIF, 6 hours post CPB.Experimental data shown that may induce MIF secretion by...
A 39-year-old previously healthy woman presented to the emergency department with a 1-day history of headache and an unprecedented seizure. physical examination patient was normal. Laboratory testing cranial computed tomography (CT) were unremarkable. After 5 months, due persistent headaches new seizures, second CT scan performed, which showed hypodense region between left thalamus basal ganglia, suggesting lacunar infarction (Figure 1a). Magnetic resonance imaging (MRI) revealed cystic 1b)....
Abstract Introduction Mucoepidermoid carcinoma (MEC) is a tumor originated from the epithelium of glandular excretory ducts and has highly variable biological potential. It most prevalent cancer salivary glands. The present report aims to describe case nasal mucoepidermoid that developed after adjuvant radiotherapy (RT) treatment recurrent pituitary macroadenoma. Case Report Male patient, 62 years old, presented with epistaxis on right, associated intense pulsatile headache, visual...
Introduction: The most common cause of the spontaneous Cushing syndrome is Disease (CD, 60–70% patients). CD results from supraphysiologic levels adrenocorticotropic hormone (ACTH) secreted by a pituitary corticotroph adenoma. effects elevated serum cortisol are manifold and poorly tolerated, transsphenoidal surgery standard treatment. goals to normalize ACTH levels, restore normal pituitary–adrenal axis, eventually reverse peripheral manifestations comorbidities steroid excess.
