Diagnostic pitfalls of echography in a case of hepatic cavernous hemangioma

: An ecographic study of the liver in a 55-year-old female, with a history of mastectomy for a breast ductal cancer, showed multiple focal lesions. On computer tomography, we interpreted these lesions as metastatic disease. 99m Tc-labeled RBC showed non-homogeneous flow distribution in the right lobe of the liver. Fine needle aspiration biopsy under ecographic guidance showed no metastatic disease, and suggested a vascular lesion. The presence of spindle-shaped cells, reactive for CD 34 and for factor VIII, enabled definitive diagnosis of angiomatous lesion. Cytological confirmation of each hepatic mass is a mandatory prerequisite for any therapy.
