Key result
Multimodal resection, chemo, and radiotherapy yields disease-free survival on follow-up in rare vascular tumor.
Why the study?
Primary intimal sarcoma of the pulmonary artery is a rare, aggressive malignancy that presents diagnostic and therapeutic challenges due to nonspecific symptoms and late detection.
Case Report (n=1)
A multidisciplinary approach combining advanced imaging, surgical resection, chemotherapy, and radiotherapy can effectively manage primary intimal sarcoma of the pulmonary artery.
Multimodal therapy may aid rare pulmonary artery intimal sarcoma cases; leaves open optimal regimen and generalizability.
Primary intimal sarcoma of the pulmonary artery is a rare and aggressive malignancy that presents significant diagnostic and therapeutic challenges due to its nonspecific symptoms and propensity for late detection. This case report aimed to elucidate the diagnostic journey, surgical intervention, and multidisciplinary management of this rare entity. In September 2023, a 42-year-old male presented with dyspnea on exertion and retrosternal chest pain, classified as NYHA FC II. Initial investigations, including ECG and lab tests, indicated tachycardia and elevated troponin and NT-pro-BNP levels. Transthoracic and transesophageal echocardiography identified a multilobulated mass in the right ventricular outflow tract and main pulmonary artery. Cardiac MRI and CT angiography confirmed a high-grade pleomorphic spindle cell tumor, leading to surgical resection in October 2023. Histopathology confirmed intimal sarcoma. Postsurgery, the patient underwent chemotherapy and radiotherapy, showing significant clinical improvement and no recurrence on follow-up PET-CT. This case highlights the importance of a multidisciplinary approach in diagnosing and managing primary intimal sarcoma of the pulmonary artery, emphasizing the role of advanced imaging, timely surgical intervention, and combined chemotherapy with radiotherapy in improving patient outcomes.

Alizadehasl et al. (2024) conducted a case report in Primary intimal sarcoma of the pulmonary artery (n=1). Surgical resection, chemotherapy, and radiotherapy was evaluated on Clinical improvement and disease recurrence. Surgical resection followed by gemcitabine, docetaxel, and radiotherapy achieved significant clinical improvement with no evidence of disease recurrence on follow-up PET-CT.
