Objective: To evaluate the efficacy and safety of percutaneous core needle biopsy (PCNB) using ultrasound (US)-guided and contrast-enhanced ultrasound (CEUS)-guided procedures for anterior mediastinal masses (AMMs). Methods: In total, 284 consecutive patients (166 men, 118 women; mean age, 43.0 ± 18.4 years) who underwent PCNB for AMMs were enrolled. Patients were divided into the US-guided group (n = 133) and the CEUS-guided group (n = 151). PCNB was performed using a core needle (16-gauge or 18-gauge). Internal necrosis, diagnostic yield, and diagnostic accuracy were compared between the two groups. Results: The predominant final diagnosis of the cases in this study was thymoma (29.7%), lymphoma (20.5%), thymic carcinoma (13.3%), and germ cell tumour (13.3%), respectively. There was no significant difference in patient age, sex, number of percutaneous biopsies, or display rate of internal necrosis on conventional US between the two groups. The rate of internal necrosis of the lesions was significantly higher after contrast agent injection (72.2% vs. 41.7%; P < 0.001). The CEUS-guided group had a higher diagnostic yield than the US-guided group (100% vs. 89.5%, P < 0.001). There was no significant difference between the diagnostic accuracy of the CEUS-guided and US-guided groups (97.3% vs. 97.4%; P = 1.000). None of the patients experienced adverse reactions or complications after US-guided or CEUS-guided PCNB. Conclusions: CEUS-guided PCNB can improve the diagnostic yield by optimizing the biopsy procedure.
