Intralobar sequestration of the lung

This paper reports four cases of a broncho-pulmonary mass, supplied by an aberrant artery, occurring in the lower lobe of the lung. The object in presenting these cases is twofold; to draw attention to the diversity of the radiological picture and to discuss the effect of the systemic aberrant vessel on the production of the condition. Details of 43 cases reported since 1948, relevant to any association that may exist between the aberrant artery and the lung change, are set out (Table I). Findlay and Maier (1951) reviewed the literature up to 1948 and collected 17 cases of aberrant arteries arising from the thoracic aorta and eight cases from the abdominal aorta. The cases reported by Pryce, Sellors, and Blair (1947) were not included in thi
