The purpose of our study was to compare the imaging characteristics atypical teratoid-rhabdoid tumor with medulloblastoma and seek distinguishing features that can aid in preoperative diagnosis.Preoperative MRI examinations 55 patients (36 medulloblastomas 19 tumors) were analyzed retrospectively. Imaging assessed conventional CT. Diffusion-weighted (DWI) available 27 (19 eight tumors). Apparent diffusion coefficient (ADC) values calculated for 14 six tumors.Both tumors general...
<h3>BACKGROUND AND PURPOSE:</h3> Children with shunted hydrocephalus have been undergoing surveillance neuroimaging, generally in the form of head CT, for evaluation ventricular size. As life expectancy these children has improved due to better shunt technology and medical care, risks related ionizing radiation incurred during multiple CT examinations that they are expected undergo throughout their lifetime become a concern. The purpose this study is estimate LAR developing fatal cancer size...
<h3>BACKGROUND AND PURPOSE:</h3> Pleomorphic xanthoastrocytomas are rare astrocytic neoplasms of childhood and young adulthood. The purpose this retrospective review was to evaluate MR imaging features pediatric pleomorphic with an emphasis on diffusion imaging. <h3>MATERIALS METHODS:</h3> Review the neuro-oncology data base revealed 11 patients (range, 4.7–16.1 years) xanthoastroacytomas 9 these having preoperative available. Six had Demographics, histopathology slides, conventional...
<h3>BACKGROUND AND PURPOSE:</h3> Cervical MR imaging has demonstrated a utility for detecting soft tissue injury in nonaccidental trauma. The purpose of this study was to identify the incidence and types cervical spine on trauma correlate with parenchymal brain findings head CT. <h3>MATERIALS METHODS:</h3> A retrospective review children diagnosed tertiary referral pediatric hospital over 8 years performed. Inclusion criteria were younger than 5 age, confirmed diagnosis trauma, within 1 week...
The purposes of this study were to determine the accuracy radiology reports in diagnosis pediatric pilomatricoma and describe characteristic imaging findings a large cohort.Query pathology database between January 2009 February 2014 yielded 623 specimens from 596 patients. Seventy-four patients (41 girls, 33 boys; mean age, 8.9 years) underwent 80 excised lesions. Ninety studies available (58 ultrasound, 11 CT, 21 MRI). Radiology reviewed. lesions evaluated for location, size,...
This report presents a series of 5 pediatric patients with disseminated pilocytic astrocytomas and frequent nonfusion activating mutations. Genetic variants in these patients' tumors include BRAF p.Val600Glu, p.Val600Asp, KRAS p.Gly60_Gln62ins7. The 2 BRAF-mutated were treated dabrafenib or combination plus trametinib. had either near complete resolution the primary tumor (BRAF p.Val600Glu) stable p.Val600Asp). Both showed improvement leptomeningeal dissemination without significant...
We identified preoperative parameters associated with increased risk of intraoperative Wilms tumor spill.We retrospectively reviewed an institutional database patients diagnosed between 2000 and 2008. Inclusion criteria consisted available abdominal computerized tomogram pathological stage I to IV disease. Patient characteristics neoadjuvant chemotherapy use were noted. After blinding, a radiologist parameters, calculating volume assigning radiological stage.Of 67 41 (22 males, 19 females)...
Clinical clearance of a child's cervical spine after trauma is often challenging because impaired mental status or an unreliable neurologic examination. Magnetic resonance imaging (MRI) the criterion standard for excluding ligamentous injury in children but constrained by long image acquisition times and frequent need anesthesia. Limited-sequence magnetic (LSMRI) used evaluating evolution traumatic brain may also be useful while potentially avoiding The purpose this study was to assess...
Few reports describe the outcome and prognostic factors for children with gangliogliomas. The objective of this report was to progression-free survival (PFS) low-grade gangliogliomas identify risk tumor progression.A retrospective study performed in who were evaluated treated neuro-oncology department between 1986 2006 determine subsequent total 38 newly diagnosed included report. Thirty-four surgery alone, 3 subtotal resection radiation therapy, 1 chemotherapy. follow-up ranged from 4...
Abstract Background The aim of this study was to assess outcomes medical and surgical treatment intratonsillar abscess in children. Methods charts children with were reviewed obtain information on history physical examination, imaging, management, follow‐up assessment. Results Eleven (six male, five female; age range, 4–18 years) identified. common complaints included sore throat, fever, odynophagia. Asymmetric tonsil hypertrophy present nine patients erythema tonsils all patients....
Background Despite intensive therapy, children with metastatic and recurrent sarcoma or neuroblastoma have a poor prognosis. Magnetic resonance guided high intensity focused ultrasound (MR‐HIFU) is noninvasive technique allowing the delivery of targeted energy under MR imaging guidance. MR‐HIFU may be used to ablate tumors without ionizing radiation target chemotherapy using hyperthermia. Here, we evaluated anatomic locations assess technical feasibility therapy for solid tumors. Procedure...
Recurrent pleomorphic adenoma of the parotid gland is a significant problem. Rates have been as high 40% in some series patients who undergone surgery for primary lesion. In imaging literature, anecdotal case reports show multiple lesions recurrent adenoma. Our aim was to analyze determine reliability tool diagnosing disease.Medical records with referred our institution were retrospectively reviewed. Before second surgery, MR had performed 15 patients. We reevaluated and scored studies...
<h3>BACKGROUND AND PURPOSE:</h3> Although utility of diffusion MR imaging in the preoperative diagnosis common pediatric cerebellar tumors is generally recognized, its added value has not been systematically studied previously. The purpose this study was to evaluate impact on accuracy among reviewers with different experience levels. <h3>MATERIALS METHODS:</h3> Review neuro-oncology data base yielded 96 patients whose brain included both (<i>b</i> = 1000 s/mm<sup>2</sup>) and ADC maps. There...
