Lung cancer is the number one cause of cancer-related deaths in the United States. Involvement of pericardium occurs once cancer has progressed to stage IV which can cause massive effusion in the pericardial sac. This can lead to cardiac tamponade which can be fatal very quickly if untreated. The following is a two patient case series in which both patients presented with large pericardial effusion. The first patient sought medical attention due to new onset palpitations and was found to have hemorrhagic pericardial effusion and pulmonary embolism (PE). The second patient presented with shortness of breath. Investigations revealed that she had pericardial and pleural effusions along with multiple metastases throughout the body. Both patients ended up with a diagnosis of non-small cell lung cancer (NSCLC) with BRAF mutation. One patient had V600E mutation; other patient had a variant p.D594N mutation. Both patients also had expression of PD-L1.

Management of acute pulmonary embolism depends immensely on rapid diagnosis and early intervention. Transthoracic echocardiography has gained favorability in scenarios where diagnostic computed tomography angiography is not feasible. McConnell's sign, an echocardiographic finding of segmental right ventricular wall‐motion abnormality with apical sparing, is highly specific and may guide therapeutic intervention. We present the case of a 59‐year‐old man who was found to have acute pulmonary embolism with obstructive shock, managed successfully with thrombolytic therapy after identification of McConnell's sign. We review current literature and develop a framework for the integration of echocardiography into the multimodal approach to management.

Hepatopulmonary syndrome (HPS) is characterized by impaired oxygenation due to pulmonary vascular dilatation in patients with end-stage liver disease. At our center, we identified 29 patients who were listed for liver transplantation (LT) with a model for end-stage liver disease exception for HPS between 2001 and 2012. Five of these patients were found to have concurrent interstitial lung disease (ILD). The chest high-resolution computed-tomography demonstrated ground-glass opacities and subpleural reticulation, most consistent with nonspecific interstitial pneumonia (NSIP). All four of our patients who underwent LT experienced prolonged hypoxemia postoperatively, with one surgery-related death. However, the three surviving patients had eventual resolution of their hypoxemia with no evidence of ILD progression. In conclusion, we report a high prevalence of ILD, most consistent with NSIP, among patients with HPS. Although there may be increased perioperative risks, the finding of ILD in patients with HPS should not be considered an absolute contraindication to LT.
