Differentiating neoplastic from non-neoplastic spinal cord pathologies may be challenging due to overlapping clinical and radiological features. Spinal cord tumors, which comprise only 2-4% of central nervous system tumors, are rarer than non-tumoral myelopathies of inflammatory, vascular, or infectious origins. The risk of neurological deterioration and the high rate of false negatives or misdiagnoses associated with spinal cord biopsies require a cautious approach.

Methods: In total, 45 consecutive patients (51% women, mean (SD) age 53 (18) years) with HHT referred to a reference center for treatment of recurrent PAVM were retrospectively included from April 2014 to July 2021. Inclusion criteria included evidence of PAVM recurrence on CT or angiography, embolization using Onyx and a minimal 1-year-follow-up CT or angiography.
Purpose: The purpose of this study was to characterize the technical capabilities and feasibility of a large field-of-view clinical spectral photon-counting computed tomography (SPCCT) prototype for high-resolution (HR) lung imaging.
Materials And Methods: Measurement of modulation transfer function (MTF) and acquisition of a line pairs phantom were performed. An anthropomorphic lung nodule phantom was scanned with standard (120kVp, 62mAs), low (120kVp, 11mAs), and ultra-low (80kVp, 3mAs) radiation doses.

Objective: Patients with systemic sclerosis and both pulmonary hypertension and interstitial lung disease (SSc-PH-ILD) generally carry a worse prognosis than patients with SSc and pulmonary arterial hypertension (SSc-PAH) without ILD. There is no evidence of the efficacy of PAH therapies in SSc-PH-ILD. We undertook this study to compare survival of and response to treatment in patients with SSc-PH-ILD and those with SSc-PAH.

In the absence of systemic immunodeficiency, decision of NTM lung disease treatment must relies on a careful risk/benefit assessment, given the requirement of long-term administration of multidrug therapies supported by limited evidence. The primary objective was to identify the factors associated with anti-NTM treatment initiation.

Thus, apparently there is no benefit to perform an array CGH in case of HHT. However, ENG has been involved in a contiguous gene syndrome due to a de novo 9q33.

Our objective was to determine if CT findings were associated with frequency of brain abscess and ischaemic stroke.
Methods: This retrospective study included patients with HHT-related PAVMs.
Background: Interstitial pneumonia with autoimmune features (IPAF) has recently been defined by an international Taskforce to characterize interstitial lung disease associated with systemic manifestations limited to subtle serological and clinical autoimmune abnormalities and not fulfilling the international criteria for the diagnosis of a given connective tissue disease.
Objective: to report on a series of patients with IPAF, and to compare their outcome to that of a cohort of patients with idiopathic pulmonary fibrosis (IPF).
Methods: Retrospective analysis of consecutive patients in a single institution over a 3-year period.
Objective: To evaluate the value of the diameter of the draining vein of pulmonary arteriovenous malformation (PAVM) on unenhanced chest MDCT in diagnosing reperfusion after percutaneous vaso-occlusion therapy.
Methods: We retrospectively reviewed our long-term experience of patients with hereditary haemorrhagic telangiectasia and selected cases on the following criteria: an initial pulmonary angiogram with embolotherapy of at least one PAVM, a follow-up MDCT examination in the following year followed by a second pulmonary angiogram with embolotherapy if needed. Follow-up unenhanced chest MDCT examinations were analyzed blindly from results of pulmonary artery angiogram and clinical data, the diameter of the efferent vein close to the PAVM sac was measured, then compared to those of pulmonary artery angiogram as a gold standard.
Objectives: Endovascular treatment of thoracic aortic lesions appears to be advantageous. However, long-term outcomes remain poorly reported. This retrospective study reported 6-year outcomes of thoracic endovascular aortic repair.
View Article and Find Full Text PDFBackground: Specimens collected by CT scan-guided transthoracic core-needle biopsy (TTNB) are frequently used for the diagnosis of lung nodules, but the clinical value of negative results has not been sufficiently investigated. We sought to determine the negative predictive value (NPV) of TTNB specimens and investigate predictive factors of negative results.
Methods: All consecutive TTNBs performed in three centers between 2006 and 2012 were included.
Despite the lack of evidence in the literature, we report the case of a 25-year-old man involved in a road traffic accident, who had an inferior vena cava (IVC) injury and severe lung contusion with parenchymal bleeding requiring an extracorporeal membrane oxygenation (ECMO). An emergency procedure to implant a stent graft was successful in repairing the IVC injury. Moreover, we think that ECMO, in addition to providing oxygenation, reduced bleeding by creating a negative pressure along the injured IVC.

Materials And Methods: Seven patients with eight documented patent PAVMs underwent a 4D-MRA with keyhole and viewsharing compression at 3T with the following parameters: spatial resolution 0.87 × 0.
Objective: Connective tissue diseases (CTDs) are associated with several interstitial lung diseases. The aim of this study was to describe the recently individualized syndrome of combined pulmonary fibrosis and emphysema (CPFE) in a population of patients with CTD.
Methods: In this multicenter study, we retrospectively investigated data from patients with CTD who also have CPFE.
Purpose: To evaluate the use of a recently developed fast-clearing ultrasmall superparamagnetic iron oxide (USPIO) for detection of vascular inflammation in atherosclerotic plaque.
Materials And Methods: The study protocol was approved by the animal experimentation ethics committee. A recently introduced USPIO, P904, and a reference-standard USPIO, ferumoxtran-10, were tested in a rabbit model of induced aortic atherosclerosis.
Objective: To evaluate the accuracy of delayed-enhanced multidetector computed tomography (MSCT) for differentiating between myocarditis and myocardial infarction in patients with normal x-ray coronary angiography.
Methods: Twelve consecutive patients referred for acute chest pain and normal coronary arteries on x-ray coronary angiography were involved in this study. Delayed-enhanced MSCT and postgadolinium delayed-enhanced magnetic resonance imaging (MRI) examinations were performed within 36 hours and 4 days, respectively, after patient admission.
This is the first case report of successful anesthesia management in a high-risk neurological procedure in a patient with PHACE syndrome. PHACE syndrome is rare but an important clinical entity. Anesthesiologists should be aware of the neurological, otolaryngogical, and vascular risk associated with this syndrome.
