Case report of medical thoracoscopy and endobronchial ultrasound bronchoscopy in the workup of giant solitary fibrous tumor of the pleura.

Solitary fibrous tumor of the pleura (SFTP) is a rare tumor of fibroblastic origin. It can be quite vascular, and its surgical management carries the risk of a major intra-operative bleed. The pre-operative use of endobronchial ultrasound (EBUS) to visualize the vascular supply of the tumor has not been reported.We report a case of a patient presenting with progressive shortness of breath and cough who was found to have a very large pleural-based tumor. We describe the use of medical thoracoscopy and EBUS to establish the diagnosis of SFTP and to characterize the blood supply of the tumor.In the future, EBUS may provide an alternative to conventional angiography for both mapping and embolizing tumor blood supply.
