title: [Regional distribution of perfusion and ventilation in hamartoangiomyomatosis of the lung].
abstract: We investigated regional distribution of perfusion and ventilation in three cases of hamartoangiomyomatosis (HAM) by 133Xe gas and 99mTc-MAA. In two cases, 133Xe washout were dominantly delayed in middle lung field and in the third case, it was delayed in upper lung field. This distribution was different from the result in the other chronic obstructive pulmonary disease (COPD). In most cases of COPD, 133Xe washout was prominently delayed in the lower lung field. Distribution of pulmonary perfusion in HAM were consistent with that of ventilation as in COPD.
