title: Thallium-201 scintigraphic visualization at rest of a dilated and hypertrophied right ventricle in a patient with sarcoidosis complicated by cor pulmonale.
abstract: Visualization, by resting TI-201 scintigraphy, of a markedly enlarged right ventricle (RV) in a 48-year-old black man with a 20-year history of pulmonary sarcoidosis is presented. The RV was three to four times larger than the left ventricle. Sarcoidosis resulted in marked distortion of the thoracic contents, as shown by the radiograph. This distortion possibly accounts for optimal scintigraphic visualization of the enlarged RV in the left lateral projection rather than in the left anterior projection. Because of the distortion, the chest radiograph could not be used to evaluate the cardiac contour; TI-201 scintigraphy demonstrated the RV enlargement.
