Key result
Primary pulmonary artery tumors frequently mimic pulmonary embolism, requiring multimodality imaging and prompt tissue diagnosis.
Why the study?
Primary pulmonary artery tumors are rare, challenging to diagnose, and lack a unified understanding and standard for diagnosis and treatment.
This review emphasizes the clinical, imaging, and histopathologic features necessary to accurately differentiate primary pulmonary artery tumors from pulmonary embolism to avoid harmful treatment delays.

May warrant PPAT consideration in refractory PE; extends diagnostic insights but leaves open standardized criteria and prospective validation.
Primary pulmonary artery tumors (PPATs), originating from the pulmonary artery intima, are rare tumors characterized by pulmonary artery luminal occlusion and pulmonary hypertension. Diagnosis of this rare entity is a challenging dilemma with the need for a high expertise in the radiological and pathological identification of PPATs. computed tomographic pulmonary angiography of PPATs may show filling defects, which are easily misdiagnosed. The radionuclide scan, along with other imaging examinations, can assist with the diagnosis, but the pathological diagnosis requires a puncture or surgical resection. Most primary pulmonary artery tumors are malignant, with poor prognosis and lack of specificity in clinical manifestations. However, there is no unified understanding and standard for diagnosis and treatment. In this review, we discuss the status, diagnosis, and treatment of primary pulmonary artery tumors, as well as how clinicians can better understand and treat the disease.

Liu et al. (2023) conducted a review in Primary pulmonary artery tumors. Primary pulmonary artery tumors was evaluated. Primary pulmonary artery tumors are rare malignancies that are frequently misdiagnosed as pulmonary embolism and require comprehensive multimodality imaging and prompt biopsy or surgical excision for accurate diagnosis and management.
