Ultrasound-guided fine-needle aspiration biopsy in the diagnosis of hepatic hemangioma.

Fine-needle biopsy of hepatic hemangioma is discussed on the basis of a series of 10 biopsies performed on eight patients. The fine needle biopsies were executed because of the atypical sonographic pattern of some lesions, or in order to exclude malignancy for others (five patients were known to have neoplasms). No complication presented during or after the punctures. In six cases cytologic samples included capillary vessels or endothelial cells, supplying the diagnosis of hemangioma. It is concluded that fine-needle biopsy of a hepatic hemangioma is not loaded with complications, and moreover can yield true positive information in 60% of cases.
