Right Ventricular Infarction Presenting With Refractory Hypoxia Due to Shunting Across a Patent Foramen Ovale

Right ventricular infarction is often associated with significant morbidity and mortality. Here, we report a case of right ventricular infarction associated with persistent hypoxia due to acute right-to-left shunting through a patent foramen ovale

Case Report Internal Jugular Venous Pseudoaneurysm in a Patient with Heart Failure and Severe Tricuspid Regurgitation

The differential diagnosis of a lateral neck mass includes a number of possible etiologies. While jugular venous aneurysms and pseudoaneurysms are rare entities, they should be considered in the differential diagnosis of a pulsatile lateral neck mass. We present a case of an idiopathic jugular venous pseudoaneurysm and its association with worsening tricuspid regurgitation in a patient with heart failure with preserved ejection fraction

Pheochromocytoma Masquerading as “Diabetic Ketoacidosis”

Diabetic ketoacidosis is a routinely encountered diagnosis in medicine. Physicians are trained early on to look for precipitants. Most clinicians assess for medication compliance, infection, ischemia, and the like. We present a case of pheochromocytoma presenting as “diabetic ketoacidosis.” The case serves as an example for broadening the differential diagnosis for patients with similar presentations. Additionally, the case helps inform our understanding of the so-called “stress reactions” that are commonly invoked in clinical rationale
