Purpose: Incisional biopsy is still used to obtain material for a straightforward histological diagnosis in
musculoskeletal lesions. The aim of our study was to evaluate 1) the percentage of diagnostic procedures,
2) diagnostic accuracy, and 3) the incidence of complications after imaging-guided percutaneous biopsy
(PCB).
Case Series: This is a retrospective analysis of imaging-guided PCB performed between January 2016 and
September 2019 by fluoroscopy in bone lesions or under ultrasound-guidance in soft tissue lesions.
Specimens were classified as diagnostic or non-diagnostic according to the pathologist’s report; diagnostic
accuracy was determined by comparing histopathological results from biopsy and tumor resection. PCB
was diagnostic in 94% and 97% of cases, with a diagnostic accuracy for detecting tumor disease in soft
tissue and bone lesions of 98% and 100%, respectively. No complications were observed.
Discussion: The PCB is safe, minimally invasive, and cost-effective; thus, it should be the gold standard
for the diagnosis of musculoskeletal lesions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
