Hot tub lung
Updates to Article Attributes
Hot tub lung refers to pulmonary disease in otherwise healthy patients that can occur by secondary exposure to aerosolisedaerosolized non-tuberculous mycobacteria in contaminated hot hot water-steam (classically described in hot tubs, hence the name)4
Clinical presentation
It can present as an acute pulmonary illness with fever fever and dyspnoea.
Pathology
The pathology of hot hot tub lung is is thought to be related related to an infection, a hypersensitivity reaction (the latter is more favoured) or both. Therefore it is also sometimes classified as a precipitant for hypersentivity pneumonitis. A granulomatous pneumonitis then tends to occur.
Hypersensitivity pneumonitis-like reaction to mycobacteria can also occur from exposures other than just hot tubs.
Radiographic features
CT/HRCT chest
Imaging appreancesappearances can mimic asubacute hypersensitivity pneumonitis from other causes 1. Described features include 1,5:
- areas of ground glass attenuation
- centrilobular pulmonary nodules
- air trapping on expiratory images
- beading of the interlobular septae
