Key result
Primary pulmonary artery leiomyosarcoma is an extremely rare disease often misdiagnosed as pulmonary thromboembolism, leading to delayed diagnosis and high mortality.
Why the study?
Pulmonary artery leiomyosarcoma is extremely rare and easily misdiagnosed as pulmonary thromboembolism, leading to delayed diagnosis, improper treatment, and extremely high mortality.
Case Report
Highlights the importance of distinguishing rare pulmonary artery leiomyosarcoma from pulmonary thromboembolism using enhanced CT to avoid delayed diagnosis and high mortality.
Alerts clinicians to differentiate leiomyosarcoma from thromboembolism mimics; leaves open prospective validation of enhanced CT and early surgery.
Pulmonary artery leiomyosarcoma is an extremely rare disease, with only a few dozen cases reported worldwide to date. This disease is easily misdiagnosed as pulmonary thromboembolism, leading to improper treatment and accurate diagnosis in the later stages of the disease. Furthermore, this delayed diagnosis may also be the reason for the extremely high mortality rate of patients suffering from it. Early invasive surgery with the goal of complete surgical resection is the standard treatment method. Chemotherapy and radiation therapy have been tried with variable outcomes.
