Abstract:
We presented a case of primary lymphoma of the sternoclavicular joint. A 67-year-old woman with a history of swelling at the sternoclavicular joint region was considered as osteoarthritis initially. Chest CT found a soft tissue mass around the sternoclavicular joint. Biopsy demonstrated diffuse large B-cell lymphoma. The subsequent FDG PET/CT revealed FDG-avid articular destruction with surrounding soft tissue mass without any other abnormal findings, suggesting a primary extranodal lymphoma of sternoclavicular joint.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

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...
