Abstract:
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.

Secondary Lymphoid Organs
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
