METHOD FOR DIFFERENTIAL DIAGNOSTICS OF FOCAL FORMATIONS IN ANTERIOR PHRENICOCOSTAL SINUS OF PLEURA IN CASE OF PLEURAL EFFUSION Russian patent published in 2017 - IPC A61B8/08 

FIELD: medicine.

SUBSTANCE: ultrasound examination is performed in the vertical position of the patient by longitudinal scanning of the anterior phrenicocostal sinus of the pleura by a convection sensor with a frequency of 3.5-5.0 MHz. First, scanning is performed along the parasternal line from the intercostal space above the costal arch perpendicular to the thoracic wall. Then the sensor is moved down and installed under the costal arch with a cranial incline. In the presence of elongated formations lobed middle-echo structure with pleural effusions in the anterior phrenicocostal sinus at the background of pleural effusion, which perform swinging motion during breathing, fatty suspensions are diagnosed. In the presence of flattened or rounded formations with a homogeneous hypoechoic structure not performing pulse movements during breathing, metastases are diagnosed.

EFFECT: increased accuracy of diagnosis due to detailed study of the anterior phrenicocostal sinus of the pleura and identification of characteristic differential-diagnostic features of the detected formations.
