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 2x1.5x1.5 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.

Enhanced CT scan demonstrated a clearly enhanced nodule containing focal low attenuation, and clearly enhanced tubular structures, thought to be dilated vessels, were seen in the left lower lobe (Fig. 1A). Wedge resection of the lung was performed, and gross examination showed that tumor size was 2.0x1.5x1.5 cm (Fig. 1B). Microscopic examination revealed dilated vessels corresponding to the enhanced tubular structures demonstrated by CT scan (Fig. 1C).

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).
