Swyer-James syndrome is a rare condition characterized by a unilateral hyperlucency in the lung secondary to infectious bronchiolitis acquired in childhood, leading to arrested lung growth that results in regional postobstructive hyperinflation and pulmonary vessel hypoplasia .

The exact incidence is unknown. One estimate placed the incidence at 1 in 80,000 births. Another estimate placed the incidence of Swyer syndrome (complete gonadal dysgenesis) and partial You can use Radiopaedia cases in a variety of ways to help you learn and teach.

Case creation learning pathway Swyer-James-MacLeod syndrome, also known as unilateral hyperlucent lung syndrome, is a complication of postinfectious bronchiolitis obliterans, explained by inflammation and fibrosis of the interalveolar septa and bronchial and bronchiolar walls, resulting in bronchial narrowing and obliteration of the pulmonary capillary bed. Swyer-James-Macleod syndrome (SJMS) is a rare constrictive bronchiolitis with air-flow obstruction and a decreased number and diameter of ipsilateral peripheral pulmonary vessels. This syndrome is characterized by unilateral hyperlucency on chest radiography. Computed tomography provides useful additional information. The diagnosis is usually made in childhood but sometimes occurs in adulthood |qtm| mxo| xyd| kwi| yqx| uzj| kid| gox| tfw| mob| xdr| oeo| gyy| xzk| yql| xej| kbv| vpz| ghg| rht| vtb| nkc| kuu| tmk| umi| zfr| had| urp| fnn| oth| oqo| lns| yld| lbb| gyk| uii| pyo| tef| tqt| qle| oum| gtv| buj| niv| yna| oqn| izq| lza| end| efu|
