“…62 Boomerang signs are pleural effusions shaped as a boomerang that can be visualized using anterior transverse substernal scans of the posterior right hemithorax showing both the diaphragm interface and posterior chest wall. 65 Plankton signs appear as internal echoes on dynamic chest US because of floating debris within the pleural effusion that swirl with respiration or cardiac motion (Figure 6). 66…”

Over the last 20 years, scientific literature and interest on chest/lung ultrasound (LUS) have exponentially increased. Interpreting mixed—anatomical and artifactual—pictures determined the need of a proposal of a new nomenclature of artifacts and signs to simplify learning, spread, and implementation of this technique. The aim of this review is to collect and analyze different signs and artifacts reported in the history of chest ultrasound regarding normal lung, pleural pathologies, and lung consolidations. By reviewing the possible physical and anatomical interpretation of these artifacts and signs reported in the literature, this work aims to present the AdET (Accademia di Ecografia Toracica) proposal of nomenclature and to bring order between published studies.

“…10) refers to the floating debris in a pleural effusion which appears as punctiform internal echoes swirling with respiration or cardiac pulsations on dynamic lung ultrasound. When seen, this sign suggests that the effusion is likely to be exudative or haemorrhagic in nature (27) (the term plankton refers to small and microscopic organisms floating in large bodies of water).…”

Point-of-care ultrasound has become firmly established in acute and critical care settings, and is now increasingly being used as an important tool in the assessment of the lungs. In this article, we briefly describe the technique of lung ultrasound and the various lines and signs commonly encountered during sonography of the lung, namely the normally visualised A- and T-lines and the bat sign, sliding sign (power slide sign on colour Doppler), sea-shore sign, curtain sign, and the lung pulse. We have also described signs seen in various pathological conditions like B-lines seen in cases of increased lung density; the quad sign, sinusoid sign, thoracic spine sign, plankton sign and the jelly fish sign seen in pleural effusion; the stratosphere sign and the lung point sign seen in pneumothorax; the shred/fractal sign and tissue-like sign in consolidation, and the double lung point sign seen in transient tachypnoea of the newborn. With adequate and appropriate training, lung ultrasound can be effectively utilised as a pointof-care investigation.
