• Percutaneous ultrasound-guided core needle biopsy is a well-established method in the diagnosis of musculoskeletal tumors. It is unclear which factors contribute the most to a successful biopsy. The aim of the study was to determine the value of ultrasound-guided core needle biopsy of solid lesions in the musculoskeletal system using a 16-gauge needle. A retrospective analysis performed at a regional sarcoma center over one year included patients referred for ultrasound-guided biopsy of musculoskeletal soft tissue lesions. At least 6 months’ clinical and radiological follow-up, results from repeat or excisional biopsy, or interventional treatment, served as outcome reference. The biopsy procedure and yield were analyzed. The biopsy was classified as ‘diagnostic’ when a definitive diagnosis could be made on the first biopsy, and ‘accurate’ when only the malignant or benign nature of the tumor could be determined. From 102 referrals for biopsy of soft tissue lesions in 2019, a total of 73 biopsies of solid lesions with a 16-gauge cutting needle were included (73 patients). There were 34 males and 39 females, with a mean age of 57.7 years. The overall proportion of diagnostic biopsies was 84%, for malignant lesions 88% and benign lesions 81%. The tumor could be classified as malignant or benign in 12 patients (16%) (accurate biopsy). It was possible to discriminate between malignant and benign lesions in each case. The majority of biopsied lesions were benign 64% ( = 47). The diagnostic value of ultrasound-guided percutaneous core needle biopsy of musculoskeletal soft tissue lesions performed with 16-gauge needle is good, with a high rate of diagnostic biopsies, both for benign and malignant lesions.
