Extrinsic pulmonary stenosis in primary mediastinal B-cellular lymphoma.
We describe the case of a 34-year-old man with a history of asthenia and excessive fatigability. Transthoracic echocardiography showed a mass in the right ventricular outflow tract with a peak systolic gradient of 52 mmHg. Contrast-enhanced CT confirmed the presence of a lobulated mass, which extensively filled the anterior mediastinum, infiltrating the pulmonary artery trunk up to occupying the right ventricular outflow tract. CT-guided biopsy revealed primary mediastinal B-cellular lymphoma. The patient underwent chemotherapy, achieving complete remission of the disease at the 12-month follow-up, while the gradient across the pulmonary artery dropped from 52 mmHg to 14 mmHg.
