[Morphological diagnosis of pseudocystic tumors of the liver]

Ten cases of pseudocystic hepatic tumors were observed during the past ten years. This entity is very rare in comparison with benign hepatic cysts. Careful analysis of the characteristics of these lesions usually allows to differentiate them from benign cysts. Of importance are wall thickness, mural nodules and fluid/fluid levels on ultrasound and/or computed tomography scanning. In our series, sonography depicted the true morphology of these cystic masses more clearly than computed tomography. If definitive diagnosis cannot be made by morphologic examinations, percutaneous aspiration of the cystic lesion, a simple and safe method, should be considered.
