We describe an unusual case of an invasive thymoma protruding into the superior vena cava and left brachiocephalic vein through the thymic veins in a 64-year-old patient. The tumor was resected with a bypass of the right brachiocephalic vein and right atrium. Although this type of growth form is rare for an invasive thymoma, this case suggests that in surgical procedures for thymomas, meticulous examination of the thymic veins is necessary to avoid leaving residual tumor.

Invasive thymoma commonly infiltrates mediastinal structures; however, intracardiac extension from an intracaval growth is rare. An unusual case of an invasive thymoma protruding into the RA is here described. A left brachiocephalic vein (LBCV) tumor appeared through the thymic veins of a 50-year-old female patient.

We report a rare case of protrusion of an invasive thymoma with intraluminal growth through the thymic vein into the superior vena cava (SVC) without direct invasion of the vessel walls. The tumor and left brachiocephalic vein were resected, and the tumor in the SVC was removed with temporal bypass of the right brachiocephalic vein and right auricle. Histopathological finding showed that the thymoma had protruded via a thymic vein.

Superior vena cava syndrome (SVCS) is usually caused by extrinsic compression or invasion of the superior vena cava (SVC) by malignant tumors involving mediastinal structures. Although thymomas are well-known causes of SVCS, cases of SVCS caused by malignant thymomas protruding into adjacent vessels draining the SVC with thrombosis have been very rarely reported worldwide. We experienced a 39-year-old female patient with SVCS that developed after the direct invasion of the left brachiocephalic vein (LBCV) and SVC by an anterior mediastinal mass with a high maximum standardized uptake value on the chest computed tomography (CT) and positron emission tomography-CT.

The authors describe the incidence and various uptake patterns of Tc-99m sestamibi (MIBI) in the extracardiac area due to unusual causes on myocardial perfusion single photon emission computed tomography (SPECT) studies. Seven patients are presented in whom incidental extracardiac findings were observed during the interpretation of the raw data besides the routine evaluation of myocardial reconstructed SPECT slices. These 7 patients were detected out of 582 consecutive patients (1.
