We have experienced 18 patients having pleural effusion and/or peripheral lung masses in conventional sonographic examination of the upper abdomen. Ultrasonography make it possible to recognize the morphology and motion of the diaphragm, especially when abnormal shadow was seen on the chest radiographs.
We have also experienced the inverted right hemidiaphragm which has thought not to occur because of the supportive influence of the liver.
16 cases of our cases have pleural effusions of varying etiologies, and in 2 cases ultrasonography is useful to evaluate the etiology of the pleural effusions.
Real time sonography is useful to assess the base of the lung, the morphology and motion of the diaphragm and the subphrenic spaces, and may help clarify the etiology of the pleural effusion.
So we think that careful observation to the diaphragm and its surrounding should be made on daily upper abdominal ultrasonic examination.
