METHOD FOR DIFFERENTIAL DIAGNOSTICS OF ABDOMINOMEDIASTINAL LIPOMA AND PERICARDIAC CELOMIC CYST Russian patent published in 2008 - IPC A61B8/00 

FIELD: medicine, radiation diagnostics, ultrasound diagnostics.

SUBSTANCE: it is necessary to carry out ultrasound investigation of right cardiodiaphragmatic angle in a patient's vertical position with the help of a sector sensor unit at frequency of 3.5-5.0 MHz. At first, one should fulfill transverse scanning from under xiphoid process at the direction of scanning axis towards right shoulder or from the right parasternally from intercostal area being above the site of costal arch fixation towards the sternum. Then it is necessary to fulfill longitudinal ultrasound scanning to carry out comparative analysis of the images obtained. One should conclude upon abdominomediastinal lipoma in case of the presence of hypoechogenic triangular formation at heterogeneous structure due to a lot of multiple linear echogenic signals, being capsule-free and having the connection with preperitoneal fatty fiber. The diagnosis of pericardiac celomic cyst should be established at the presence of oval formation at anechogenic homogeneous structure being restricted with a thin echogenic capsule and not connected with preperitoneal fatty fiber. The innovation enables to increase the accuracy of differential diagnostics of abdominomediastinal lipomas and pericardiac celomic cysts by 18% against roentgenological trials.

EFFECT: higher accuracy and efficiency of diagnostics.
