Contrast-enhanced ultrasound (CEUS) guided drainage in the treatment of a patient with lung abscess secondary to hypervirulent Klebsiella pneumoniae (hvKP) infection: A case report

Abstract

Hypervirulent Klebsiella pneumoniae (hvKP) can cause lung abscess, serious infection, and has a high mortality. Drainage plays a key role in the treatment of lung abscess secondary to hvKP. Contrast-enhanced ultrasound (CEUS) can identify necrotic areas within peripheral pulmonary lesions. We report a case in which thoracic CEUS using solution of sulfur hexafluoride microbubbles (SonoVue®, Bracco, Milan, Italy) was better than computed tomography (CT) in depicting lung abscess from consolidation secondary to hvKP, and its role in guiding drainage of lung abscess. CEUS is a promising imaging technique for confirming an appropriate time for drainage of lung abscess secondary to hvKP, for point-of-care application in critical patients with impaired renal function which may be aggravated by CT contrast medium.

WFUMB Technological Review: How to Perform Contrast-Enhanced Ultrasound of the Lung

“…Intracavitary CEUS is an established diagnostic tool (Yusuf et al 2018) and was described as useful also in the pleural cavity to detect malposition of pleural catheters and better identify locations (Deganello et al 2017;Bi et al 2021;Rafailidis et al 2021) or to assist USguided drainage of pulmonary abscesses (Chen et al 2021;Rafailidis et al 2021). Furthermore, CEUS may be helpful in differentiating various causes of pleural effusion (Safai Zadeh et al, 2021f;Safai Zadeh et al, 2021[No.…”
