We have experienced a case of chronic pancreatitis which showed interesting ultrasonographic findings. The patient had two homogenous, well-defined hypoechoic lesions in the body and the tail of the pancreas. Histologically, these hypoechoic findings were due to severe fibrosis caused by chronic pancreatitis. Edematous change and malignancy were not seen. As a result of this research, it was proved that severe fibrosis of the chronic pancreatitis was showed as hypoechoic lesion ultrasonographically.
