Background:Pulmonary sarcomatoid carcinoma (PSC) is a rare, hidden-onset, rapidly progressive, poorly differentiated non-small cell lung cancer. Its accurate diagnosis is troublesome. Herein, we reported a case of pulmonary sarcomatoid carcinoma diagnosed by contrast-enhanced ultrasound angiography-guided lung biopsy and described the imaging features in this case. Case presentations: A 75-year-old female patient developed a productive cough and edema of both lower limbs, accompanied by post-exercise chest tightness and shortness of breath. Diagnosis: Neoplastic space-occupying lesion of the upper right lung. Interventions: The pathological diagnosis of the right lung mass was achieved through contrast-enhanced ultrasound (CEUS) and CEUS-guided core needle biopsy. Outcomes: The biopsy results supported the pathological diagnosis of pulmonary sarcomatoid carcinoma. The typical imaging features of CEUS angiography for such a lesion in this case differing from contrast-enhanced computed tomography have not been reported in previous literature. Conclusion: CEUS angiography-guided lung biopsy is a safe and effective diagnostic method for pulmonary sarcomatoid carcinoma, which is superior to enhanced computed tomography-guided biopsy as to the space-occupying lesion adjacent to the thoracic wall. CEUS has potential value in the diagnosis of PSC.
