Intralobar pulmonary sequestration with three aberrant arteries in a 75-year-old patient.
A rare case of intralobular pulmonary sequestration (ILS) with three aberrant arteries occurred in a 75-year-old woman. A contrast-enhanced chest CT scan demonstrated a paraaortic, partially enhanced mass shadow and two small liner enhancements in the upper portion of the mass. A definitive diagnosis could not be rendered with a CT scan alone, but the findings suggested bronchopulmonary sequestration with multiple aberrant arteries. Surgery confirmed three fine aberrant arteries arising from the thoracic aorta and entering the left lower lobe basal segment. Judging from the patient's age and multiple aberrant arteries, the sequestrated lung appeared as if it were acquired. However, all aberrant arteries were of the elastic type histologically. This finding suggested that ILS was not an acquired condition but a congenital malformation.
