Abstract:
Superior vena cava (SVC) syndrome is an uncommon yet potentially fatal syndrome occurring after intrinsic or extrinsic compression to the SVC. While there are multiple emerging etiologies for this phenomenon, malignancy remains the most common. It is characterized by several symptoms including facial swelling, extremity swelling, shortness of breath, and headaches. We present the case of a 59-year-old female with a past medical history of cocaine abuse who was admitted for upper extremity swelling and facial edema. Imaging revealed a right suprahilar mass compressing a branch of the right pulmonary artery and SVC, in addition to bilateral segmental and subsegmental pulmonary emboli. She underwent an emergent biopsy and SVC stenting, with immunostaining revealing small cell lung cancer (SCLC). This case highlights a severe presentation of SVC syndrome caused by previously undetected SCLC.

01:11Overview of Systemic Veins
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the...
01:18Veins of the Abdomen and Pelvis
The inferior vena cava is fed by numerous smaller veins. The lumbar veins, for instance, drain the posterior abdominal wall, emptying both directly into the inferior vena cava and into the...
01:19Veins of Thorax
The azygos vein, positioned just right of the midline and anterior to the vertebral column, begins at the junction of the right ascending lumbar and subcostal veins, terminating in the superior vena cava. This vein drains blood from the right side of the thoracic wall, thoracic viscera, and posterior abdominal wall.

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
