Key result
Multimodal imaging and histopathology enable accurate early PAIS diagnosis to avoid misdiagnosis as PE.
Why the study?
Pulmonary artery intimal sarcoma is frequently misdiagnosed as pulmonary embolism due to nonspecific findings, leading to delayed diagnosis and poor prognosis.
Case Report (n=1)
Multimodal imaging and histopathology are essential for the early and accurate diagnosis of pulmonary artery intimal sarcoma to avoid misdiagnosis as pulmonary embolism.
Should not yet change practice; leaves open prospective validation of multimodal diagnosis for pulmonary artery sarcoma.
Pulmonary artery intimal sarcoma (PAIS) is a rare and highly aggressive malignancy. Due to nonspecific clinical symptoms, imaging features, and laboratory findings, PAIS is frequently misdiagnosed as pulmonary embolism (PE), leading to delayed diagnosis and poor prognosis. Multimodal imaging, including echocardiography, Positron Emission Tomography-Computed Tomography (PET/CT), and histopathology, is critical for accurate diagnosis. We present a case of PAIS with atypical manifestations, aiming to improve early clinical recognition and emphasize the role of a multimodal approach in early diagnosis for PAIS patients.

Wu et al. (2025) conducted a case report in Pulmonary artery intimal sarcoma (PAIS) (n=1). Multimodal imaging (echocardiography, PET/CT, and histopathology) was evaluated on Accurate diagnosis of PAIS. A multimodal approach including echocardiography, PET/CT, and histopathology is critical for the accurate early diagnosis of pulmonary artery intimal sarcoma to prevent misdiagnosis as pulmonary embolism.
