Primary Pulmonary Epithelioid Hemangioendothelioma: A Rare Cause of PET-Negative Pulmonary Nodules

We report here a case of primary pulmonary epithelioid hemangioendothelioma diagnosed in a 67-year-old Caucasian man, presenting with exertion dyspnoea, dry cough, and multiple bilateral pulmonary nodules revealed by computed tomography. At the 18F-fluorodeoxyglucose positron emission tomography, these nodules were negative. The histopathological diagnosis was made on a pulmonary wedge resection (performed during video-thoracoscopic surgery)

Right-to-left interatrial shunt secondary to right hemidiaphragmatic paralysis: An unusual scenario for urgent percutaneous closure of patent foramen ovale

A 66 year-old female presented with a refractory hypoxaemia in association with an isolated paralysis of the right hemidiaphragm. Transoesophageal echocardiography (TEE) with both colour Doppler and bubble test demonstrated a significant patent foramen ovale (PFO)-mediated right-to-left shunt (RTLS) without an increased interatrial pressure gradient. The PFO was urgently closed by deployment of an AMPLATZER(\uae) occluder device, resulting in complete recovery of the arterial oxygen saturation and patient's symptoms. As noted on TEE, the RTLS was due to redirection of blood flow from the inferior vena cava directly through the PFO secondary to distortion of the cardiac anatomy by right hemidiaphragmatic paralysis
