Fdg Avidity

A 53-year-old female with a history of metastatic left arm melanoma presented for F(18) fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) which showed a moderately FDG avid focus at her port catheter tip near the cavoatrial junction. Although catheter tip related FDG avidity has previously been suggested to be bland thrombus or infection, melanoma can metastasize to unusual locations including the superior vena cava. In addition, the patient had an elevated risk of anticoagulation due to a history of hemorrhagic brain metastases. Therefore, confirmatory cardiac magnetic resonance (CMR) was obtained and findings were consistent with bland catheter-related thrombus.

Abstract Background This is a case report of a primary cardiac lymphoma with an unusual clinical presentation. We hereby illustrate the characteristic features of cardiac lymphomas by multimodality imaging and particularly cardiac magnetic resonance (CMR) that can help reach a timely diagnosis non-invasively and guide treatment decisions. Case summary A 58-year-old woman, without significant past medical history, presented with a 3-week history of shortness of breath associated with facial and neck swelling. Transthoracic echocardiogram confirmed the presence of a cardiac mass in the right atrium. Cardiac magnetic resonance helped to characterize the mass, assess its haemodynamic significance and relation to cardiac structures, and reach a non-invasive diagnosis that was crucial for guiding treatment decisions and interventions. Discussion Cardiac masses have distinct imaging features that can help differentiate malignant from benign cardiac tumours. More specifically, primary cardiac lymphomas can be relatively easy diagnosed by CMR in most cases thanks to their characteristic imaging appearance.

Abstract Background Diagnosis of aortic graft infection is challenging, and delayed diagnosis is associated with poor prognosis. Positron emission tomography/computed tomography (PET/CT) has improved diagnostic accuracy. Case summary A patient with a history of congenital heart disease was admitted due to fever. He had a history of four cardiac surgeries, including the Bentall procedure for endocarditis. Blood cultures were negative. A semi-mobile mass was detected in the distal portion of the aortic tube graft in echocardiography. PET/CT scan was used to confirm tube graft infection and to support proceeding to cardiac surgery. Discussion Using multimodality imaging, including PET/CT scan in combination with echocardiography, can improve diagnostic accuracy for the detection of aortic tube graft infection, infection of prosthetic valves, or intra-cardiac devices, especially in high-risk surgical cases.

Abstract Background Cardiac sarcoidosis (CS) is associated with poor prognosis, yet the clinical diagnosis is often challenging. Advanced cardiac imaging including cardiac magnetic resonance (CMR) and positron emission tomographic (PET) have emerged as useful modalities to diagnose CS. Case summary A 66-year-old woman presented with palpitations. A 24-h Holter monitor detected a high premature ventricular contraction burden of 25.6%. She underwent two transthoracic echocardiograms; both showed normal results. Stress perfusion CMR did not show any evidence of ischaemic aetiology; however, myocardial lesions detected by late gadolinium enhancement (LGE) imaging raised suspicion for CS. While there was no myocardial uptake of fluorodeoxyglucose (FDG) in subsequent cardiac PET, high FDG uptake was seen in hilar lymph nodes. Lymph node biopsy confirmed the diagnosis of sarcoidosis. Discussion Cardiac magnetic resonance and PET imaging are designed to evaluate different aspects CS pathophysiology. The characteristic LGE in the absence of increased FDG uptake suggested inactive CS with residual myocardial scarring.

AbstractPulmonary arterial hypertension (PAH) is a vascular disorder associated with significant morbidity and mortality. The pathophysiology of PAH remains controversial, but the only currently available therapies for PAH are pharmacological pulmonary artery vasodilation, decreasing right ventricular (RV) afterload, and relieving symptoms. By now, there is no therapy being able to minimize vascular remodeling processes and thus to reverse or delay the natural history of the disease. It has been generally thought that reduction of RV preload was detrimental, which deteriorated the systemic hemodynamics. In the present study, however, we repetitively and briefly occluded (RBO) both superior vena cava and inferior vena cava by ligation (occlusion for less than 5 seconds then re-open for 30 seconds and repeated 5 cycles as one sequence, 1 sequence every 6 hours) to intermittently restrict RV preload, for continuous 24 hours, total 5 sequences, in the Sugen 5416 (VEGF receptor blocker) and hypoxia induced PAH rat models and we found this strategy was beneficial for lowering pulmonary vascular resistance (PVR).
