Computed Tomography in Nonneoplastic Space-Occupying Intracranial Lesions
1981
A number of nonneoplastic intracranial space-occupying lesions may resemble neoplasms in the CT scan, and definitive diagnosis is not possible with CT studies alone in many cases. Misinterpretations are possible, even when all clinical data are considered in the interpretation of the CT scan. However, the most accurate possiblepreoperative diagnosis is a prerequisite for decisions on therapeutic strategy and surgical approach. Therefore some cases may require the full range of conventional neuroradiological techniques and careful consideration of clinical findings for correct interpretation of the CT scan with its consequences for therapy. Table 6 summarizes the most common alternatives in …
Detection of benign hilar bile duct stenoses – A retrospective analysis in 250 patients with suspicion of Klatskin tumour
2016
Introduction The aim of this study was to identify clinical, laboratory and radiological parameters to distinguish benign from malignant stenoses of the proximal bile duct. Methods Between 1997 and 2011, 250 patients were referred to our clinic with hilar bile duct stenoses suspicious for Klatskin tumour. Medical histories, clinical data, pre-interventional laboratory tests, imaging findings, as well as therapeutic approach and patient outcome were compared to final histological results. All data were retrieved from our prospectively maintained database and analysed retrospectively. Results We found benign bile duct lesions in 34 patients (13.6%). Among the entire study population, uni- and…
Embolization with ethylene vinyl alcohol copolymer (Onyx®) for peripheral hemostatic and non-hemostatic applications: a feasibility and safety study
2018
International audience; Background: Onyx® is a liquid embolic agent, which is approved for the treatment of cerebral vascular lesions but still rarely used in peripheral interventional radiology. The goal of this study is to report the feasibility and safety of embolization with Onyx® for peripheral hemostatic and non-hemostatic endovascular procedures.Methods: Retrospective study of all consecutive patients who underwent visceral or peripheral embolization with Onyx® for hemostatic or non-hemostatic purpose in our department between May 2014 and November 2016. Demographic data, clinical presentation, underlying etiology, culprit vessel, endovascular procedure, pain during embolization, out…
Focal hepatic intrinsically hyperattenuating lesions at unenhanced CT: Not always calcifications.
2021
Due to the growing use of CT, there has been an increase in the frequency of detecting focal liver lesions. Intrinsically hyperattenuating hepatic lesions or pseudolesions are not uncommon at unenhanced CT. Hyperattenuating hepatic lesions can be divided into non-calcified and calcified. Causes of intrinsic hyperattenuation include hemorrhage, thrombosis, and calcifications. Focal liver lesions can show hyperattenuation on unenhanced CT in case of severe liver steatosis. Recognition of etiologies associated with hyperattenuation on unenhanced CT can help the radiologist in characterizing focal liver lesions and pseudolesions. In this paper, we describe the spectrum of intrinsically hyperatt…
Brainstem Auditory Evoked Potentials and Visual Potentials in Kawasaki Disease: An Observational Monocentric Study
2020
Background: Kawasaki Disease is a systemic vasculitis, particularly involving coronary arteries. Rare involvement of other vascular districts is described, as central nervous system arteries, leading to a vasculitic neuropathy. Sensorineural hearing loss and alterations of evoked potentials are uncommonly reported complications.Methods: In an observational monocentric study, 59 children (37 males; 22 females; mean age: 2.7 ± 2.2 years) with documented Kawasaki Disease were enrolled. No risk factors for hearing loss and/or neurological impairment were identified in the cohort. Brainstem auditory evoked potentials and visual evoked potentials were correlated with clinical, hamatological and r…
Frailty and risk of complications in head and neck oncologic surgery. Systematic review and dose-response meta-analysis
2021
Background There is emerging evidence that frail individuals present a decreased physiological reserve, decreased ability to maintain homeostasis, and increased vulnerability to stressors. The concept of frailty has become increasingly recognized as a valuable measure in oncological surgical patients, including those with head and neck cancer. Preoperative screening for frailty may provide an individualized risk assessment that can be used by an interdisciplinary team for preoperative counseling and to improve outcomes. The aim of this meta-analysis was to evaluate the relationship between frailty and the risk of major postoperative complications in frail individuals submitted to head and n…
Bilateral cyclic cheek lesions related to premenstrual syndrome: a multifactorial pathogenesis?
2009
Introduction Cheek biting is a chronic, usually innocuous, self-inXicted injury that often occurs as a parafunctional habit. Case report We report an unusual case of bilateral cyclic cheek lesions in a 34-year-old woman characterized by hyperkeratinization near the biting edges of the teeth and hematic lesions accompanied by a cheek swelling sensation, without pain and burning. The lesions coincided with a premenstrual syndrome, characterized by Xuid retention Introduction Cheek biting is a chronic, usually innocuous, self-inXicted injury that often occurs as a parafunctional habit. Case report We report an unusual case of bilateral cyclic cheek lesions in a 34-year-old woman characterized …
Classification of Intracranial Tumors
1981
L. Bruns (1914) stated in Krause’s “General Neurosurgery” that brain tumors included all neoplasms growing within the cranial cavity and that these might be divided into three groups: (1) genuine tumors, (2) granulomatous lesions, and (3) parasites. Current use of the term “brain tumor” is more precise and limited to the first of L. Bruns’ categories. Even so, brain tumors represent a large and inhomoge-neous group. The comparison and evaluation of such a diverse set of observations is only possible after making a systematic classification of pertinent data.
Correlation between rCBF, Angiography, EEG and Scanning in Brain Tumors
1969
The findings with techniques of different sensitivity, and which investigate different aspects of brain structure and/or function are difficult to correlate. However, such a comparison should help in elucidating the physiopathological mechanisms of brain lesions and the postoperative clinical evolution and prognosis in cases of brain tumors.
The prevalence of oral mucosal lesions in the patients visiting a dental school in Northern India in relation to sex, site and distribution: A retros…
2011
Objective: To determine the distribution of oro-mucosal lesions in patients of Maharishi Markendeshwer College of Dental Sciences and Research, (MMCDSR), Mullana. Further to identify sex predilection and different sites which are more susceptible to different oro-mucosal lesions. Materials and methods: A hospital based retrospective study was carried out from 1st January 2007 till 31st December 2009 at (MMCDSR), Mullana. A total of 451 biopsy reports were studied. Distribution and prevalence of oro-mucosal lesions among the data were analyzed using SPSS software package version 13. Results: There was no mention of habits in the biopsy reports of 85.4 % (385 patients) of the subjects. Out of…
