Solitary fibrous tumor of the pleura: a rare cause of elevation of the right lung base

摘要

A 42-year-old female nonsmoker with no history ofcomorbidities was admitted to the hospital with a 6-monthhistory of right-sided chest pain and dyspnea. A chest X-rayshowed marked elevation of the right lung base (Figures1A and 1B). Laboratory test results were unremarkable.A magnetic resonance imaging scan of the chest revealeda heterogeneous mass in the right hemithorax, withintermediate signal intensity on T1- and T2-weightedimages (Figures 1C and 1D). A transthoracic needlebiopsy was performed, and the results were inconclusive.The patient underwent radical surgical resection by openthoracotomy. The tumor was pedunculated, with freemargins, measuring approximately 12 × 11 × 6 cm, andthe pedicle was connected to the mediastinal pleura. Thefinal diagnosis was solitary fibrous tumor of the pleura(SFTP). The postoperative evolution was uneventful.
