A ruptured dissecting aneurysm of the vertebrobasilar artery (VBA-DA) is a well-known cause acute subarachnoid hemorrhage (SAH) with high rate early rebleeding. Internal trapping parent artery, including dissected segment, one most reliable techniques to prevent However, for VBA-DA not suitable internal trapping, optimal treatment method has been well established. The authors describe their experience in treating VBA-DAs amenable stent-assisted coil embolization (SAC) followed by...
Background: Sinus X-ray imaging is still used in the initial evaluation of paranasal sinusitis, which diagnosed by opacification or air/fluid level sinuses and best seen Waters' view sinus (PNS). The objective this study was to investigate feasibility recognizing maxillary sinusitis features using PNS images, as well propose most effective method determining a reasonable consensus multiple deep learning models. Methods: A total 4,860 patients, included 2,430 normal subjects each, underwent...
We hypothesized that coexisting extranidal arterial aneurysms (EAs) would be associated with an increased risk of incident intracranial hemorrhage (ICH) from brain arteriovenous malformation (BAVM) rupture.To determine the presence EAs and compare sources locations ICH, we retrospectively reviewed computed tomographic, magnetic resonance imaging, angiographic studies patients who presented between 1990 1999. were defined as saccular luminal dilations parent feeding vessels proximally...
Rhinocerebral mucormycosis is an acute fulminant opportunistic fungal infection usually seen in diabetic or immunocompromised patients. The fungi that cause inoculate the nasal mucosa and may spread to paranasal sinuses, orbit, brain. Our patient initially presented with mild ethmoid sinusitis. At time, brain MRI contrast-enhanced MR angiography were grossly normal. However, aggravation of sinusitis extension right orbit anterior cranial fossa rapidly developed within two months. Moreover,...
A 59-year-old woman with classic manifestations of hyperparathyroidism associated multiple endocrine neoplasia type 1 presented a right adrenal mass and two pituitary microadenomas on imaging studies. For evaluation hypercalcemia, (99m) Tc-MIBI scintigraphy was done showed focal uptake at the thyroid level anterior neck. Subsequent neck sonography several nodules, but there no parathyroid tumor. Percutaneous fine-needle aspiration dominant nodule indicated follicular nodule. After surgery,...
Background: Cognitive deficit is a common problem in patients with chronic obstructive pulmonary disease (COPD). The aim of this study was to prospectively evaluate if MRI can demonstrate microstructural volume loss and the diffusion anisotropic change subjects COPD, compared cognitively normal (CN) subjects. Methods: Six severe 13 moderate 12 CN underwent isotropic volumetric T1-weighted imaging tensor (DTI). Voxel-based statistical analyses among groups were performed on brain volumes,...
Pseudoaneurysm of the superficial temporal artery is an unusual complication. Diagnosis based on clinical findings and radiologic study. The standard treatment surgical ligation resection, other options include intervention, thrombin injection, conservative treatment. In this article, authors report several cases pseudoaneurysm suggest a protocol to manage artery. We conducted retrospective review 11 patients who underwent between April 2002 July 2011. According duration aneurysm, we divided...
Purpose: The hyperintense acute reperfusion marker (HARM) is a delayed enhancement of the subarachnoid or subpial space observed on post contrast FLAIR images, and associated with permeability changes to blood-brain barrier (BBB) in stroke. We investigated relationship between HARM stroke etiology based Trial Org 10172 Acute Stroke Treatment (TOAST) classification. In addition, we evaluated locations respect vascular territories anatomic compartments. Materials Methods: recruited 264...
ABSTRACT INTRODUCTION Characterizing the morphologies of occluded artery segments may help elucidate etiology chronic intracranial occlusion. We acquired high‐resolution MRI (HR‐MRI) middle cerebral (MCA) in patients with unilateral MCA occlusion and evaluated clinical findings. METHODS selected 20 consecutive who presented Proton‐density weighted HR‐MRI was using a 3.0 Tesla MRI. surveyed morphology at segment. Symptoms, presence other stenotic arteries, atherosclerosis risk factors were...
The purpose of this study was to determine whether a CT interpretation with imaging pattern analysis differentiates Kikuchi disease (KD) from the two more frequently encountered differential lymph nodes diagnoses tuberculous lymphadenopathy (TL) and reactive hyperplasia (RH).Between January 2012 July 2015, 20 patients KD (6 men, 14 women; mean age, 27.80 years), 36 RH (10 26 33.08 years) 34 TL (17 17 39.82 were pathologically diagnosed using US-guided fine needle aspiration biopsy, core or...
We report magnetic resonance image (MRI) and spectroscopy (MRS) findings in a patient of cerebral fat embolism (CFE) occurred 26-year-old woman after an autologous injection into the face. After initial neurologic symptom onset, MRI MRS data were obtained two times to investigate repeated CFE. different time intervals echo compare lesions with normal brain parenchyma. The results showed that decrease N-acetyl-aspartate, increase lactate very high early peak free lipids between 0.9 1.4 ppm at...
The presence of an intracerebral hematoma from a ruptured aneurysm is negative predictive factor and it associated with high morbidity mortality rates even though clot evacuation followed by the neck clipping performed. Endovascular coil embolization useful alternative procedure to reduce surgical rates. We report here on our experiences option endovascular placement craniotomy for evacuation.Among 312 patients who were admitted subarachnoid hemorrhage during recent three years, 119 cases...
The occurrence of a vascular perforation during an endovascular procedure is unexpected and feared complication which can be fatal. However, the incidence, risk or mechanism occur in management aneurysms remains unclear. purpose present study was to evaluate incidence coil embolization cerebral aneurysm, reveal characteristics clinical outcomes.We reviewed procedures performed for treatment 459 aneurysms. Incidence clinical, radiological technical data patients concerning were from medical...
Patients with Alzheimer disease (AD) and mild cognitive impairment (MCI) have high variability in brain tissue loss, making it difficult to use a disease-specific standard template. The objective of this study was develop an AD-specific three-dimensional (3D) T1 template evaluate the characteristics populations used form template.We obtained 3D T1-weighted images from 294 individuals, including 101 AD, 96 amnestic MCI, 97 cognitively normal (CN) elderly segmented them into different tissues...
It remains unclear why intracranial artery atherosclerosis (ICAS) is more common in Asians than Caucasians. 1,2Intracranial arterial tortuosity associated with atherosclerotic plaque, 3 and greater stroke patients ICAS those without. 4Therefore, we hypothesized that may be Caucasians, compared the between age-/sexmatched Koreans Caucasians.Among 339 "white-ethnicity" subjects who visited Health Promotion Center at Kyung Hee University Medical from 2015 to 2016, enrolled 76 without a history...
