title: Strangulation of aberrant artery in extralobar pulmonary sequestration on video imaging.
abstract: We report a case of an 18-year old female patient with symptomatic extralobar pulmonary sequestration. The initial symptom was sudden-onset right lateral abdominal pain. Enhanced computed tomography showed a 5 cm in diameter, spindle-shaped mass located in the costophrenic sinus with no aberrant artery. Exploratory thoracoscopy showed a haemorrhagic mass caused by strangulation of an aberrant vessel originating from the intercostal artery. Pathological findings revealed pulmonary sequestration with haemorrhagic infarction. The strangulated aberrant artery was clearly demonstrated by video imaging.
