From: Can ultrasound shear wave elastography differentiate between malignant and benign pleural effusions?
59 years female patient presented with dyspnea, cough and fever. The first image from above is transthoracic B-mode ultrasound shows mild-to-moderate anechoic right-sided pleural effusion (white arrow). The next two images revealing elasticity values in KPa with color coding maps of predominantly yellow/green (less stiffness, soft tissues). Although negative transthoracic ultrasound for pleural thickening, subpleural masses or pulmonary lesions, biopsy had been taken from the patient as the patient known to had right breast cancer in order to exclude metastatic etiology. By histopathology pleural biopsy revealed inflammatory reactions. SWE values all below 54.2 kPa with maximum value equal 41.6 kPa compatible with final diagnosis of benign nature
