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 ...

A-line (ultrasound)
An A-line is an ultrasonographic artifact appreciated during the 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...

B-line (ultrasound)
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
Linear atelectasis (plural: atelectases), and also known as discoid, plate or band atelectasis, refers to a focal area of subsegmental atelectasis that has a linear shape. Linear atelectasis may appear to be horizontal, oblique or perpendicular and is very common. It usually occurs as a conseque...
Article
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...

Bilateral hypertranslucent hemithoraces
Bilateral hypertranslucent hemithoraces is the presence of decreased density of the hemithoraces bilaterally on a plain chest radiograph. This hypertranslucency, a.k.a. hyperlucency, may be focal or diffuse 1.
Also see unilateral hypertranslucent hemithorax.

Tropical pulmonary eosinophilia
Tropical pulmonary eosinophilia is a pulmonary condition caused by an overreactive immune response to microfilaria trapped in the lungs. Tropical pulmonary eosinophilia is a distinct entity with specific symptoms and diagnostic criteria that differentiate it from other types of eosinophilia in t...

Methotrexate induced pneumonitis
Methotrexate induced pneumonitis is characterized by interstitial inflammation of the lung parenchyma which can be life-threatening. Methotrexate induced pneumonitis falls under a subtype under the broader category of methotrexate induced lung disease.
Diagnosis of methotrexate-induced pneumoni...
