[Symptomless lung sequestration]

Two cases of asymptomatic intralobar pulmonary sequestrations are reported. Chest radiographs showed a solid intrapulmonary mass left posterior at the base. By computed tomography the exact localization and relationship of the sequesters to the surrounding tissue were demonstrated, and a bolus injection of contrast medium revealed the supplying arteries. The arteriography showed a single arterial supply in both cases and their exact course. In the late phase the pulmonary veins were visualized. Finally a suggested diagnostic workup is given.
