Thoracic spine sign (ultrasound)
The thoracic spine sign on lung ultrasound is an indirect indicator of the presence of a pleural effusion or hemothorax. It represents the visualization of the vertebral bodies in the thoracic cavity above the diaphragm which are usually not seen unless there is a fluid collection. Radiographi...

Bedside lung ultrasound in emergency (approach)
Bedside lung ultrasound in emergency (BLUE) is a basic point-of-care ultrasound (POCUS) examination performed for undifferentiated respiratory failure at the bedside, immediately after the physical examination, and before echocardiography. The protocol is simple and dichotomous, and takes fewer...
Double lung point sign (Ultrasound)
The double lung point sign refers to a sharp boundary found between relatively aerated superior lung fields and coalescent "B‐lines" (representing interstitial edema) in the basal lung fields, with a reported sensitivity of 45.6%-76.7% and a specificity of 94.8%-100% 1,3 in diagnosing transient ...
Pneumonia - ultrasound
Published 25 Aug 2018
An a-line is an ultrasonographic artifact appreciated during insonation of an aerated lung. 1 The term may be applied to the horizontal, echogenic long path reverberation artifacts that occur beneath the pleural line at multiples of the distance between the ultrasound probe and the visceral-par...
The B-line is an artifact relevant in lung ultrasonography. As originally described, it has seven defining features 1: a hydroaeric comet-tail artifact arising from the pleural line hyperechoic well-deﬁned extending indeﬁnitely erasing A-lines moving in concert with lung sliding, if lung...
Brachytherapy seed migration to the lung
Brachytherapy seed migration to the lung is a known complication of radioactive seed therapy. These seeds are used for localized treatment of malignancies, most commonly prostate cancer. Regarding staging, nearly 79% of the cases are localized, 12% are regional and 5% present with distant disea...

Plankton sign (ultrasound)
The plankton sign refers to swirling, punctiform internal echoes within an otherwise anechoic pleural effusion which demonstrate slow, whirling dynamics, occasionally buffered by cardiac and respiratory impulses. When present, one may rule out a transudative effusion, and should be highly suspic...

Linear atelectasis refers to a focal area of subsegmental atelectasis that has a linear shape. Depending on its shape, it is also known as plate, discoid or band atelectasis. Linear atelectasis may appear to be horizontal, oblique or perpendicular and is very common. It usually occurs as a conse...
Jellyfish sign (ultrasound)
The jellyfish sign refers to the sonographic appearance of atelectatic lung "swimming" within a large pleural effusion. The mobility of the lung within pleural fluid implies an absence of lung consolidation and the absence of pleural adhesions 1. It is also suggestive of a transudative pleural e...
