Repeat resection for recurrence of pulmonary artery intimal sarcoma.

Pulmonary artery intimal sarcomas (PAIS) are vascular sarcomas of mesenchymal origin and are exceedingly rare. Here, we detail a 57-year-old female who presents with worsening dyspnea and computed tomography scan findings consistent with a pulmonary embolus, however, upon examination in the operating room for emergent embolectomy, was found to have a PAIS. This case report highlights this rare illness and management decisions that can optimize care of these patients.
