Swimming-induced pulmonary edema.

Swimming-induced pulmonary edema occurs when fluid accumulates in the lungs in the absence of water aspiration during swimming and produces acute shortness of breath and a cough with blood-tinged sputum. We report a case of a 58-year-old female athlete presenting with acute dyspnea during the swimming portion of a half-triathlon competition. She had complete resolution within 24 h of presentation.

A lymphoproliferative pericardial mass.

Castleman disease (CD) is a rare lymphoproliferative disorder with variable presentation and prognosis. Most CD cases are unicentric and correspond to the hyaline-vascular variant, a histopathological classification associated with better outcomes, which commonly presents as an enhancing hypervascular mediastinal mass. CD is often asymptomatic and surgically resectable. Nonetheless, surgical resection can be difficult when the lymphoid mass is causing compression of vital structures. We discuss a rare case of hyaline-vascular unicentric CD presenting as an incidental pericardial mass.
