Safety and Efficacy of Prestige Coils for Embolization of Vascular Abnormalities: The Embo-Prestige Study.

A wide variety of coils are available for vascular embolization. This study aimed to evaluate the safety and efficacy of a new Prestige coil. We carried out retrospective analysis of a multicenter's registry data collected between February 2022 and November 2022. The choice of embolization agent used to treat peripheral vascular anomalies was left to the investigator's discretion. Patients for whom at least one Prestige coil was used were included in Series 1. All other patients were included in Series 2. Efficacy and safety were evaluated. Patients were followed up for one month. In total, 220 patients were included, 110 in each series. Patients included 149 men (67.7%) and 71 women (32.3%), with a median age of 62.5 years (IQR: 35.8-73). Patient ages were similar in the two series. Complete occlusion of the targeted vessel was reported in 96.4% (n = 106/110) of patients in Series 1 and in 99.7% (n = 109/110) in Series 2. Four patients experienced non-serious adverse events (1.8%, n = 4/220): one experienced back pain and one vomiting in Series 1; one patient had off-target embolization and one a puncture site hematoma in Series 2. Sixteen patients (7.2%, n = 16/220) were lost to follow up. Improvement in the patient's general state at one month was reported in 79.0% (n = 83/105) of patients in Series 1 and in 74.7% (n = 74/99) in Series 2. Ten deaths occurred, five in Series 1 (4.8%, n = 5/105) and five in Series 2 (5.1%, n = 5/99). These deaths all concerned critically ill patients embolized for emergent arterial bleeding. In conclusion, the 1-month follow-up showed that Prestige coils, alone or in combination, are efficient and safe.

Endovascular Thrombectomy for Acute Iliofemoral Deep Venous Thrombosis Through a Jugular Approach with a Rotational Device.

PURPOSE: To report the effectiveness of pharmacomechanical catheter-directed thrombolysis (PCDT) in the management of acute iliofemoral deep venous thrombosis (DVT) via the jugular vein using a slow rotation and large-tip device (SRD) in a large cohort of patients. MATERIAL AND METHODS: From 2011 to 2021, 277 patients (mean age 45 years, 59.2% women) were treated in 6 centres with PCDT for ilio-fémoral DVT. PCDT was performed via the jugular vein and consisted of one session of fragmentation-fibrinolysis, aspiration and, if needed, angioplasty with stenting. The aim of PCDT was to achieve complete clearance of the venous thrombosis and to restore iliofemoral patency. Residual thrombotic load was assessed by angiography, venous patency by duplex ultrasound and clinical effectiveness by the rate of post-thrombotic syndrome (Villalta score > 4). RESULTS: All patients were treated via the jugular vein using an SRD, and all but one were treated with fibrinolysis. Angioplasty with stenting was performed in 84.1% of patients. After the procedure, the residual thrombotic load at the ilio-fémoral region was < 10% in 96.1% of patients. The rate of major complications was 1.8% (n = 5), the rate of minor complications was 4% (n = 11), and one patient died from pulmonary embolism (0.4%) At a median follow-up of 24 months, primary and secondary iliofemoral patency was 89.6% and 95.8%, respectively. The rate of PTS was 13.8% at 12 months. CONCLUSION: PCDT via the jugular vein using an SRD is an efficient treatment for acute iliofemoral DVT and results in high long-term venous patency and low PTS rates. Level of evidence Level 4, Case series.

Prostatic artery embolisation versus medical treatment in patients with benign prostatic hyperplasia (PARTEM): a randomised, multicentre, open-label, phase 3, superiority trial.

Background: Prostatic artery embolisation (PAE) is a minimally invasive treatment of symptomatic benign prostatic hyperplasia (BPH). Our aim was to compare patient's symptoms improvement after PAE and medical treatment. Methods: A randomised, open-label, superiority trial was set in 10 French hospitals. Patients with bothersome lower urinary tract symptoms (LUTS) defined by International Prostatic Symptom Score (IPSS) > 11 and quality of life (QoL) > 3, and BPH ≥50 ml resistant to alpha-blocker monotherapy were randomly assigned (1:1) to PAE or Combined Therapy ([CT], oral dutasteride 0.5 mg/tamsulosin hydrochloride 0.4 mg per day). Randomisation was stratified by centre, IPSS and prostate volume with a minimisation procedure. The primary outcome was the 9-month IPSS change. Primary and safety analysis were done according to the intention-to-treat (ITT) principle among patients with an evaluable primary outcome. ClinicalTrials.gov Identifier: NCT02869971. Findings: Ninety patients were randomised from September 2016 to February 2020, and 44 and 43 patients assessed for primary endpoint in PAE and CT groups, respectively. The 9-month change of IPSS was -10.0 (95% confidence interval [CI]: -11.8 to -8.3) and -5.7 (95% CI: -7.5 to -3.8) in the PAE and CT groups, respectively. This reduction was significantly greater in the PAE group than in the CT group (-4.4 [95% CI: -6.9 to -1.9], p = 0.0008). The IIEF-15 score change was 8.2 (95% CI: 2.9-13.5) and -2.8 (95% CI: -8.4 to 2.8) in the PAE and CT groups, respectively. No treatment-related AE or hospitalisation was noticed. After 9 months, 5 and 18 patients had invasive prostate re-treatment in the PAE and CT group, respectively. Interpretation: In patients with BPH ≥50 ml and bothersome LUTS resistant to alpha-blocker monotherapy, PAE provides more urinary and sexual symptoms benefit than CT up to 24 months.

Brief Report: A Multidisciplinary Initial Workup for Suspected Lung Cancer as Fast-Track Intervention to Histopathologic Diagnosis.

Guidelines for optimal timing of lung cancer diagnosis and treatment have been implemented in many countries, but the effect of fast-track interventions on the shortening of time interval is still debatable. In this study, the delay from the first specialist visit to the histopathologic diagnosis was compared between two patient cohorts: before (n = 280) and after (n = 247) implementation of a fast-track multidisciplinary diagnosis program. The cumulative incidence function curves were compared, and hazard ratio was adjusted in the Cox model. The implementation allowed a statistically significant increase in the cumulative incidence of the lung cancer histopathologic diagnosis over time. Adjusted hazard ratio for patients accrued in the post-implementation cohort was 1.22 (1.03-1.45) (p = 0.023), corresponding to a reduction of this waiting period by 18%. In conclusion, a multidisciplinary approach of the diagnostic process implemented at the initial visit allows a significant reduction of the timeline until the histopathologic diagnosis of lung cancer.

Prognosis of immune checkpoint inhibitors-induced myocarditis: a case series.

BACKGROUND: Immune checkpoint inhibitors (ICI) have transformed cancer treatment over the last decade. Alongside this therapeutic improvement, a new variety of side effects has emerged, called immune-related adverse events (irAEs), potentially affecting any organ. Among these irAEs, myocarditis is rare but life-threatening. METHODS: We conducted a multicenter cross-sectional retrospective study with the aim of better characterizing ICI-related myocarditis. Myocarditis diagnosis was based on the recent consensus statement of the International Cardio-Oncology Society. RESULTS: Twenty-nine patients were identified, from six different referral centers. Most patients (55%) were treated using anti-programmed-death 1, rather than ICI combination (35%) or anti-programmed-death-ligand 1 (10%). Transthoracic echocardiography was abnormal in 52% of them, and cardiac magnetic resonance showed abnormal features in 14/24 patients (58%). Eleven patients (38%) were classified as severe. Compared with other patients, they had more frequently pre-existing systemic autoimmune disease (45% vs 6%, p=0.018), higher troponin level on admission (42-fold the upper limit vs 3.55-fold, p=0.001), and exhibited anti-acetylcholine receptor autoantibodies (p=0.001). Seven patients (24%) had myocarditis-related death, and eight more patients died from cancer progression during follow-up. Twenty-eight patients received glucocorticoids, 10 underwent plasma exchanges, 8 received intravenous immunoglobulins, and 5 other immunosuppressants. ICI rechallenge was performed in six patients, with only one myocarditis relapse. DISCUSSION: The management of ICI-related myocarditis may be challenging and requires a multidisciplinary approach. Prognostic features are herein described and may help to allow ICI rechallenge for some patients with smoldering presentation, after an accurate evaluation of benefit-risk balance.

Efficacy and safety of prostate artery embolization for patients with lower urinary tract symptoms and indwelling urinary catheter: A retrospective multicenter study.

PURPOSE: The purpose of this multicenter study was to evaluate the clinical success at three months of prostate artery embolization (PAE), assess PAE safety in centers with various experiences and identify factors associated with PAE success. PATIENTS AND METHODS: This multicenter, retrospective study included patients who underwent PAE for lower urinary tract symptoms (LUTS) including those with indwelling urinary catheter. PAE clinical success was defined as either 25% improvement of the International Prostate Symptom Score (IPSS) or 1-point improvement of quality of life (QoL) score, or catheter removal at three months. Multivariable analyses were performed using a logistic regression adjusted on patient variables, technical parameters and center experience in PAE. RESULTS: A total of 383 men (mean age, 68.4 ± 9.7 [standard deviation] years; range: 46-94) with LUTS, including 99 (25.8%) patients with indwelling urinary catheter, were included in seven centers from January 2017 to March 2019. Five patients reported major complications (1.3%), three (0.8%) penile ulceration, three (0.8%) acute urinary retention, one (0.3%) prostatic abscess, and 56 (14.6%) minor complications. Follow up data were available for 271 patients (center 1: n = 159; other centers: n = 112). Clinical success was reported in 232 patients (85.6%). In multivariable analyses, presence of cardiovascular comorbidities (diabetes, stroke history, myocardial infarction and lower limb artery disease) was the single independent variable inversely associated with PAE clinical success (odds ratio = 0.396; 95% confidence interval: 0.17-0.91; P = 0.029). There was no center effect. CONCLUSION: Our results show that PAE is safe and effective in centers with various PAE experiences. Cardiovascular comorbidity is the single independent variable associated with PAE failure.

Somatic TEK variant with intraarticular venous malformation and knee hemarthrosis treated with rapamycin.

BACKGROUND: Venous malformations (VMs) are the most common vascular anomalies and have been associated with somatic variants in TEK. Current treatment of VM joint component might be challenging due to the size or location of some lesions or ineffective with recurrence of malformed veins. Targeted molecular therapies after identification of genetic defects might be an alternative. METHODS: We report a case with intraarticular bleeding due to VM with a TEK pathogenic somatic variant treated with rapamycin. RESULTS: A 26-year-old female patient was evaluated for right calf pain secondary to venous malformation of the right inferior limb with an intraarticular component in the right knee. Hemarthrosis and degenerative chondropathy of the knee were evidenced at MRA. Molecular diagnosis evidenced a pathogenic somatic TEK variant. Rapamycin was introduced to stop bleeding, with good tolerance and efficacy. CONCLUSION: The TEK receptor signals through the PI3K/AKT/mTOR pathway and TEK mutations have been linked to AKT activation. As rapamycin acts against angiogenesis and reduces phosphorylated-AKT levels, targeted molecular therapy should be discussed as first-line therapy in patients with proven molecular diagnosis and diffuse VM inaccessible to conventional treatment.

Differentiating between active and latent tuberculosis with chest computed tomography.

PURPOSE: The purpose of this study was to evaluate the capabilities of chest computed tomography (CT) in distinguishing between active and latent tuberculosis in patients positive for interferon-gamma release assay (IGRA) testing, and to compare the performance of CT with that of quantitative IGRA testing in a low incidence setting. MATERIALS AND METHODS: Patients with latent or active tuberculosis define by an IGRA positive test were retrospectively recruited. Sensitivity, specificity and accuracy were determined for CT variables and quantitative IGRA results. Final diagnosis of active tuberculosis was based on clinical data and microbiological culture. Univariable and multivariable analyses were performed using logistic regression model to identify CT variables associated with the diagnosis of active tuberculosis. RESULTS: A total of 92 patients with positive IGRA results who underwent CT examination were included. There were 54 men and 38 women with a mean age of 53.5±18 (SD) years (range: 40-68 years). Of them, 22 patients (24%) had positive Mycobacterium tuberculosis culture and 70 (76%) had latent tuberculosis. Among CT variables, consolidation had the greatest sensitivity (77%; 95%CI: 60-95%) and "tree-in-bud" the greatest specificity (97%; 95% CI: 93-100%) for the diagnosis of active tuberculosis. At univariable analysis "tree-in-bud", splenic calcification and non-calcified lung nodules were the significant variables independently associated with active tuberculosis. At multivariable analysis, the adjusted odds ratio of "tree-in-bud" was 42.91 (95% CI: 5.62-327.42). Using an optimal threshold of 51 spots, quantitative IGRA yielded 64% sensitivity (95% CI: 44-84%) and 61% specificity (95% CI: 50-73%) for the diagnosis of active tuberculosis. CONCLUSIONS: In a low incidence setting, chest CT, especially when "tree-in-bud" pattern is present, is superior to quantitative IGRA testing to identify patients with active tuberculosis among those with positive IGRA testing.

Selection of optimal cardiac phases for ECG-triggered coronary CT angiography in pediatrics.

PURPOSE: The use of coronary computed tomography angiography (CCTA) in children remains limited by patient's irradiation, and motion artefacts impairing image quality. Triggering the acquisition at the appropriate moment, and acquiring only necessary components of the cardiac cycle could overcome these limitations. Yet, optimal cardiac intervals to perform CCTA as a function of heart rate (HR) have not yet been addressed in pediatrics. METHODS: Fifty children with coronary artery anomalies underwent a CCTA on a wide-coverage single-beat CT scanner. Multiple phases from 25% to 85% of the R-R interval were acquired and reconstructed with 10% increments. Two radiologists independently assessed motion artifacts on each cardiac phase using a 4-point semi-quantitative scale. RESULTS: At patient level, the best phase for acquisition was found in diastole for patients with HR ≤ 75 bpm and in systole for patients with HR > 85 bpm. At coronary segments and structures level, median optimal phases were reported at 70%, 80%, 47%, 50%, and 54% of the R-R interval for patients with HR ≤ 60, 61-75, 86-100, 101-130, and >130 bpm respectively. For patients with HR between 76 and 85 bpm, no clear trend could be observed. Optimal acquisition durations represented 10% (2 phases), 20% (3 phases), 50% (multiphase), 20% (3 phases), and 10% (2 phases) of the R-R interval for patients with HR ≤ 60, 61-75, 76-100, 101-130, and >130 bpm, respectively. CONCLUSIONS: Optimal positioning and duration of CCTA acquisition intervals were investigated as a function of children's HR, to reduce motion artifacts and patient's irradiation.

Systemic air embolism depicted on systematic whole thoracic CT acquisition after percutaneous lung biopsy: Incidence and risk factors.

OBJECTIVES: To evaluate the incidence and risk factors of systemic air embolism (SAE) depicted on systematic whole thoracic CT performed after percutaneous lung biopsy. METHODS: A total of 559 CT-guided lung biopsies performed between April 2014 and May 2016 were retrospectively evaluated. SAE was defined by the presence of air in the aorta or left cardiac cavities seen on whole thorax CT images acquired after needle withdrawal. Analyzed data focused on patient (age, sex, spirometry data, emphysema on CT, therapeutics received), target lesion (location, depth, size and feature) and procedure (patient position, length of intrapulmonary needle path, number of pleural passes and of biopsy samples, operator's experience). A regression logistic model was used to identify risk factors of SAE. RESULTS: SAE was observed after 27 of the 559 lung biopsies, corresponding to a radiological incidence of 4.8% (95%CI: 3.3-7.0). Clinical incidence was 0.17% (n = 1). For 21/27 patients (78%), a targeted acquisition in the nodule area would not have included the cardiac cavities meaning SAE would have been missed. On multivariate analysis, the independent risk factors were needle path length through ventilated lung (OR: 1.13, 95%CI: 1.02-1.25, p = 0.024), number of samples (OR: 1.48, 95%CI: 1.01-2.17, p = 0.046) and prone position (OR: 3.12, 95%CI: 1.11-8.31, p = 0.031) or right-sided lateral decubitus (OR: 6.15, 95%CI: 1.66-22.85, p = 0.005). CONCLUSIONS: Asymptomatic systemic air embolism can be depicted in almost 5% of post biopsy CT examinations, when they are not limited to the targeted nodule area but include the entire thorax.

[Future of interventional radiology]. / Avenir de la radiologie interventionnelle.

Imaging-guided interventions or interventional radiology (IR) are intended to improve the efficiency and accuracy of the medical procedure regardless of the organ, as well as the safety and comfort of the patient. Currently IR concerns all medico-surgical specialties with a number of acts constantly increasing, and is today a major field of innovation that responds to a strong societal demand to move towards more and more effective treatments, but also less and less invasive. The ambulatory shift in IR is a major prospect of saving and improving the quality of care. In the field of innovations, technical developments are major for both guidance methods and interventional radiology equipment. These developments affect all organ pathologies, but it is certainly in the field of oncology that progress is fastest, with personalized medicine with new drugs targeted to optimize tolerance to treatment and maximize effects. The aim of this article is to make this specialty better known, its organization both in terms of training and the permanence of care.

Submillisievert Multiphasic Coronary Computed Tomography Angiography for Pediatric Patients With Congenital Heart Diseases.

BACKGROUND: The use of coronary computed tomography (CT) angiography in children with coronary artery anomalies is increasing. However, it remains technically demanding and the need to adapt acquisition parameters to a patient's cardiac characteristics has not yet been addressed. The aim of the study was to prospectively assess the feasibility of personalized multiphasic coronary CT angiography for pediatric patients. METHODS: Fifty pediatric patients (mean age 6.1±4.9 years) with coronary artery anomalies underwent a coronary CT angiography on a wide detector single-source CT equipment. Fifteen different acquisition patterns were used to trigger the acquisition at the best theoretical moment within the cardiac cycle. The appropriate pattern was automatically selected based on the patient's heart rate and heart rate variability, derived from the patient's ECG. Two independent radiologists qualitatively evaluated images. RESULTS: All acquisitions fully answered the clinical question for a mean effective dose of 0.97±0.34 mSv. Image quality qualified as good or excellent in 94% of cases (47/50). No examination was considered as not assessable but 6% (3/50) were scored as adequate for diagnosis. For these 3 patients, motion artifacts were the main cause of average image quality. No significant visual differences were reported between the different coronary arteries (mean score of 3.6 on a 4-point scale). No correlation between image quality and cardiac parameters were reported ( r=-0.19 and r=0.00, respectively for heart rate and heart rate variability). CONCLUSIONS: Personalized multiphasic coronary CT angiography acquisitions could be performed with diagnostic quality for a dose equivalent of <4 months of natural background irradiation.

Relationship between CT air trapping criteria and lung function in small airway impairment quantification.

BACKGROUND: Small airways are regarded as the elective anatomic site of obstruction in most chronic airway diseases. Expiratory computed tomography (CT) is increasingly used to assess obstruction at this level but there is no consensus regarding the best quantification method. We aimed to evaluate software-assisted CT quantification of air trapping for assessing small airway obstruction and determine which CT criteria better predict small airway obstruction on single breath nitrogen test (SBNT). METHODS: Eighty-nine healthy volunteers age from 60 to 90 years old, underwent spirometrically-gated inspiratory (I) and expiratory (E) CT and pulmonary function tests (PFTs) using SBNT, performed on the same day. Air trapping was estimated using dedicated software measuring on inspiratory and expiratory CT low attenuation area (LAA) lung proportion and mean lung density (MLD). CT indexes were compared to SBNT results using the Spearman correlation coefficient and hierarchical dendrogram analysis. In addition, receiver operating characteristic (ROC) curve analysis was performed to determine the optimal CT air-trapping criterion. RESULTS: 43 of 89 subjects (48,3%) had dN2 value above the threshold defining small airway obstruction (i.e. 2.5% N2/l). Expiratory to inspiratory MLD ratio (r = 0.40) and LAA for the range -850 -1024 HU (r = 0.29) and for the range -850 -910 HU (r = 0.37) were positively correlated with SBNT results. E/I MLD was the most suitable criterion for its expression. Expiratory to inspiratory MLD ratio (E/I MLD) showed the highest AUC value (0.733) for small airway obstruction assessment. CONCLUSION: Among all CT criteria, all correlating with small airway obstruction on SBNT, E/I MLD was the most suitable criterion for its expression in asymptomatic subjects with mild small airway obstruction TRIAL REGISTRATION: Registered at Clinicaltrials.gov, identifier: NCT01230879.

Intracoronary administration of darbepoetin-alpha at onset of reperfusion in acute myocardial infarction: results of the randomized Intra-Co-EpoMI trial.

BACKGROUND: Several trials investigating erythropoietin as a novel cytoprotective agent in myocardial infarction (MI) failed to translate promising preclinical results into the clinical setting. These trials could have missed crucial events occurring in the first few minutes of reperfusion. Our study differs by earlier intracoronary administration of a longer-acting erythropoietin analogue at the onset of reperfusion. AIM: To evaluate the ability of intracoronary administration of darbepoetin-alpha (DA) at the very onset of the reperfusion, to decrease infarct size (IS). METHODS: We randomly assigned 56 patients with acute ST-segment elevation MI to receive an intracoronary bolus of DA 150 µg (DA group) or normal saline (control group) at the onset of reflow obtained by primary percutaneous coronary intervention (PCI). IS and area at risk (AAR) were evaluated by biomarkers, cardiac magnetic resonance (CMR) and validated angiographical scores. RESULTS: There was no difference between groups regarding duration of ischemia, Thrombolysis in Myocardial Infarction flow grade at admission and after PCI, AAR size and extent of the collateral circulation, which are the main determinants of IS. The release of creatine kinase was not significantly different between the two groups even when adjusted to AAR size. Between 3-7 days and at 3 months, the area of hyperenhancement on CMR expressed as a percentage of the left ventricular myocardium was not significantly reduced in the DA group even when adjusted to AAR size. CONCLUSION: Early intracoronary administration of a longer-acting erythropoietin analogue in patients with acute MI at the time of reperfusion does not significantly reduce IS.

Diagnostic performance of computed tomography coronary angiography (from the Prospective National Multicenter Multivendor EVASCAN Study).

Computed tomographic coronary angiography (CTCA) has been proposed as a noninvasive test for significant coronary artery disease (CAD), but only limited data are available from prospective multicenter trials. The goal of this study was to establish the diagnostic accuracy of CTCA compared to coronary angiography (CA) in a large population of symptomatic patients with clinical indications for coronary imaging. This national, multicenter study was designed to prospectively evaluate stable patients able to undergo CTCA followed by conventional CA. Data from CTCA and CA were analyzed in a blinded fashion at central core laboratories. The main outcome was the evaluation of patient-, vessel-, and segment-based diagnostic performance of CTCA to detect or rule out significant CAD (≥50% luminal diameter reduction). Of 757 patients enrolled, 746 (mean age 61 ± 12 years, 71% men) were analyzed. They underwent CTCA followed by CA 1.7 ± 0.8 days later using a 64-detector scanner. The prevalence of significant CAD in native coronary vessels by CA was 54%. The rate of nonassessable segments by CTCA was 6%. In a patient-based analysis, sensitivity, specificity, positive and negative predictive values, and positive and negative likelihood ratios of CTCA were 91%, 50%, 68%, 83%, 1.82, and 0.18, respectively. The strongest predictors of false-negative results on CTCA were high estimated pretest probability of CAD (odds ratio [OR] 1.97, p <0.001), male gender (OR 1.5, p <0.002), diabetes (OR 1.5, p <0.0001), and age (OR 1.2, p <0.0001). In conclusion, in this large multicenter study, CTCA identified significant CAD with high sensitivity. However, in routine clinical practice, each patient should be individually evaluated, and the pretest probability of obstructive CAD should be taken into account when deciding which method, CTCA or CA, to use to diagnose its presence and severity.

Spontaneous renal artery dissection with renal infarction.

Spontaneous renal artery dissection (SRAD) is a rare entity, which often presents diagnostic difficulties because of its non-specific clinical presentation. We report six cases complicated with renal infarction, occurring in middle-aged male patients without risk factors, illustrating the difficulty and delay for diagnosing SRAD. Ultrasound and Doppler imaging were not sensitive enough to confirm the diagnosis, and contrast-enhanced abdominal computed tomography was used to correct the diagnosis and allow the clinicians to propose appropriate treatment. We conclude that considering the urgency in diagnosing and treating SRAD, contrast enhanced abdominal tomography and/or abdominal magnetic resonance imaging should be proposed as soon as a suspicion of SRAD is evoked by the clinical presentation.

Recent Toxoplasmosis Infection With Acute Myopericarditis and Persistent Troponin Elevation in an Immunocompetent Patient.

Although often considered as "begnin", acute infections in young healthy adults can lead to heart inflammation, including acute myocarditis. We report a rare case of myopericarditis in a young immunocompetent adult, in the context of recent toxoplasmosis infection. Clinical presentation was common acute pericarditis, but with risk biomarkers: high troponin I levels and multiple inflammation-compatible images on MR-scan. Diagnosis of myopericarditis was established. In spite of spontaneous favourable clinical evolution, troponin remained elevated. MR-scan is shown; acute myocarditis in the context of an acute toxoplasmosis infection is discussed.
