A case report of solitary fibrous tumor of the pleura: ultrasound diagnostic features.

Solitary fibrous tumor of the pleura is a rarely encountered clinical entity. Although the majority of these neoplasms have a benign course, the malignant form has also been reported. We describe the case of a 57-year-old male smoker with diabetes who was incidentally diagnosed on chest X-ray with a large solitary mass of the left hemithorax. The diagnostic tests included computed tomography, ultrasound, and contrast-enhanced ultrasound. Radical surgical resection was performed and histological examination confirmed a malignant solitary fibrous tumor of the pleura. The novelty of the case is the use of contrast-enhanced ultrasound in the diagnostic workup.
