Abstract

Alveolar soft-part sarcoma is a rare soft tissue sarcoma of young adults with unknown histogenesis, and the organ most frequently involved in metastasis is the lung. We report the CT findings of three patients of pulmonary metastases of alveolar soft-part sarcoma, which manifested as clearly enhanced pulmonary nodules or masses. On enhanced scans, some of the masses were seen to contain dilated and tortuous intratumoral vessels.

Figure

  • Fig. 1 A-32-year-old woman with a history of excision of alveolar soft part sarcoma involving the left foot 5 years earlier. A. Enhanced CT scan shows a well-defined, enhanced nodule. Clearly enhanced tubular structures are seen within the lesion (arrowheads), suggesting dilated vessels (attenuation: 9.2±8 H). B. Resected lung specimen shows a 2×1.5×1.5 cm sized nodule surrounded by pseudocapsule (arrows). C. Light microscopic examination demonstrates a clearly circunscribed nodule containing dilated vascular structures (arrows) which correspond to the enhanced tubular structures seen in A. The ruler in the right side of the picture is graduated in millimeters.

  • Fig. 2 A-31-year-old woman who presented with mass in the left leg, cough, and blood tinged sputum. Enhanced CT scan reveals multiple metastatic nodules in both lungs, with variable degrees of enhancement. Note the presence of an enhanced tubular vascular structure within a mass in the right lung (arrowheads).
