“…Several investigators have demonstrated hypo-plasia of the pulmonary arteries in the transradiant lung (Belcher et al, 1959); Reid and Simon, 1962). Belcher et al (1959) used pulmonary angiography to show an overall reduction of 50% in the diameter of the pulmonary artery to the transradiant lung compared with the normal side.…”

“…Belcher et al (1959) used pulmonary angiography to show an overall reduction of 50% in the diameter of the pulmonary artery to the transradiant lung compared with the normal side. They argued that a reduction in pulmonary artery size secondary to lung disease was seldom below 60% of the normal diameter and concluded that there was a primary hypoplasia of the pulmonary artery.…”

“…A recent British Medical Journal leader favours an obliterative bronchiolitis resulting from childhood infections as the cause and suggests that the term 'Macleod's syndrome' should be replaced by 'lobar bronchiolar obstruction with emphysema'. On the other hand, Belcher, Capel, Pattinson, and Smart (1959) have suggested that a congenital hypoplasia of the pulmonary artery is the predisposing factor, and Warrell and his colleagues (1970) believe that a pulmonary vascular abnormality is an important part of the condition.…”

Regional lung function in patients with increased unilateral transradiancy of the lung in the presence of cardiac disease

Regional lung function has been studied with xenon-i 33 in two patients with unilateral transradiancy of the lung and coincidental cardiac disease. One patient had severe mitral stenosis with pulmonary venous and pulmonary arterial hypertension, the other had a secundum type of atrial septal defect with a pulmonary blood flow which was increased to 25 litres per minute. In both instances the overall perfusion of the transradiant lung was diminished but the regional distribution of blood flow was the same within both the 'normal' and the transradiant lung. In the patient with mitral stenosis there was an abnormal increase in upper zone perfusion resulting in a reversal of the normal pattern of pulmonary blood flow while in the patient with an atrial septal defect the blood flow difference between the upper and lower zones was decreased and thus the normal vertical gradient was less. These studies suggest that the hypoplastic pulmonary arteries in the transradiant lung reacted in the same way to alterations in pressure and flow as the vessels in the other lung.

“…Dieses Gefässbild sowie die manchmal im Angiogramm bzw. im Tomogramm fehlende Darstellung der A. pulmonalis hat zu der Hypothese geführt [2,18,19], dass die einseitige Lungenhelligkeit vom Macleod-Typ auf einer primären Missbildung der A. pulmonalis beruhe.…”

This paper describes two cases of unilateral hyperlucency of the lung with detailed clinical roentgenologic and physiologic studies performed after documented observation of 11 and 34 years. In spite of increasing 'air-trapping' and pulmonary arterial hypertension the course of the disease is relatively rather benign. Although a review of the literature fails to reveal a unified concept of etiology, the constant finding of diffuse peripheral airway obstruction may well be the result of a severe respiratory infection in childhood. The acquaintance with this syndrome is of practical value, since the effects upon ventilation and cardiovascular dynamics as well as the higher incidence of infections are notorious.
