Solitary Fibrous Tumor of the Pleura With Abdominal Aortic Blood Supply.

A solitary fibrous tumor of the pleura (SFTP) presenting with an aberrant arterial supply from the abdominal aorta is extremely rare, and it may be difficult to distinguish from intralobar sequestration (ILS). We report the case of a 38-year-old woman who presented with acute chest pain and was subsequently found to have a 17.5-cm intrathoracic mass. After preoperative arterial embolization of its feeding vessel, this presumed ILS was resected. However, the intraoperative findings revealed a benign SFTP. Here we discuss a unique presentation of a large SFTP radiographically mimicking an ILS, and we propose a safe management strategy for this entity.
