Colonisation with Aspergillus of an intralobar pulmonary sequestration.

A 28-year-old female with cough and blood-streaked sputum

“…The areas most commonly affected are the mid and posterior basal segments of the lower lobes, with the left lung being twice as likely to be affected as the right [3]. Bronchopulmonary sequestration is classified as intra-or extralobar, depending on the pleura that envelops it.…”

“…Bronchopulmonary sequestration is classified as intra-or extralobar, depending on the pleura that envelops it. Intralobar sequestration is encapsulated by visceral pleura of the affected lobe, whereas the extralobar type is separate from normal lung tissue and encapsulated by its own visceral pleura [3]. Intralobar pulmonary sequestration, although infrequent, is more common than extralobar pulmonary sequestration.…”

“…Intralobar pulmonary sequestration, although infrequent, is more common than extralobar pulmonary sequestration. A characteristic of both intra-and extralobar sequestration is that blood flow is provided by a systemic artery, usually the abdominal aorta [3]. The association of this pathology with aspergilloma is rare [1].…”

“…This bronchopulmonary malformation has been associated with various pathologies, including aspergillus, bronco-oesophageal fistula or aortitis associated with severe rheumatoid arthritis [3].…”

Pulmonary sequestration associated with aspergillosis

“…The infections are usually pyogenic. To our knowledge, pulmonary sequestration associated with aspergillosis has only been reported in seven cases (Table I), [3][4][5][6][7][8][9] only one of which was extralobar in type. Intralobar sequestration occurs frequently in subjects under 20 years of age (not less than 50%).…”
