Abstract:
A case of pneumonitis following exposure to Mycobacterium avium intracellulare in an indoor home spa (hot tub) is presented. The patient complained of recurrent dyspnoea and wheezing. High-resolution CT showed centrilobular ground-glass nodules. Pathological correlation showed interstitial and bronchiolocentric granulomata. Biopsy cultures grew M. avium intracellulare. The patient condition improved following cessation of hot tub use.

The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
