Fine-needle aspiration (FNA) cytology is a reliable technique for rapid diagnosis in virtually every organ of the body, including bone lesions. We report on the FNA findings in a 61-yr-old male of an osteolytic sacral lesion, which determined the diagnosis of an unsuspected metastatic hepatocellular carcinoma. In this case, the diagnosis was confirmed by FNA biopsy without resorting to surgical biopsy.
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.
