Pulmonary Embolism Caused by Intravenous Leiomyosarcoma of the Lower Limb.

We report the long-term survival of a patient with PE due to a leiomyosarcoma in the deep vein. A 71-year-old woman complained of dyspnea and swelling of the left lower limb. Computed tomography revealed filling defects in the pulmonary arteries and deep vein. She was diagnosed with PE caused by venous thrombosis and treated with anticoagulant therapy. Her symptoms were prolonged, and D-dimer tests remained negative. Biopsy of the substance in the deep vein revealed leiomyosarcoma. The possibility of PE caused by extravascular or intravascular tumors should be considered when a patient is negative for D-dimer. PMID: 29321409 [PubMed - as supplied by publisher]
