Acute Mitral Valve Regurgitation Presenting With Right Upper Lobe Opacification.

There is literature describing unilateral or focal pulmonary edema due to mitral regurgitation. The proposed mechanism is a regurgitant jet propelling blood towards the orifice of a particular pulmonary vein within the left atrium, which selectively pressurizes that vein. The increased hydrostatic pressure is transmitted to the pulmonary capillaries that drain into that vein, causing focal consolidation.

Acute Stroke Presenting as Unilateral Lower Extremity Monochorea.

Stroke is a common condition that can present with a wide range of signs and symptoms based on the region of the brain experiencing impaired perfusion. As the diagnosis and treatment of acute strokes is frequently initiated in the emergency department (ED), early recognition by emergency providers is essential in providing patients with the best chance of recovery and symptom resolution while attempting to minimize the risk of disability. While lateralizing weakness, numbness, and speech changes are among the most common symptoms of a stroke, in rare cases, patients may present with subtle or atypical symptoms, necessitating a high index of suspicion as well as a thorough history and physical examination.
