متن کاملChest Wall Hemangiopericytoma-Like Solitary Fibrous Tumor of the Pleura: Case Report with Computed Tomography Findings
We present a case report of a 65-year-old woman who underwent resection of a chest wall tumor. In contrast with computed tomography, the tumor exhibited hypervascularity and was fed from the 9th intercostals artery. Histologically, the tumor was diagnosed as a cellular variant of solitary fibrous tumor of the pleura, with branching “staghorn” vessels and hypervascularity. The tumor thus resembl...
