“…Chest radiographic findings include ipsilateral cardiac and mediastinal displacement, absent pulmonary arterial shadow, smaller hemithorax, elevation of the hemidiaphragm, and paucity of lung vascular markings on the affected side. There may be hyperinflation and herniation of the contralateral lung across the midline [15,16]. A ventilation-perfusion scan shows the ipsilateral absence of perfusion with intact ventilation.…”

Background: Unilateral absence of pulmonary artery (UAPA) is a rare congenital disease of pulmonary circulation, which is often accompanied by other cardiovascular anomalies. Infrequently, it may remain undiagnosed until adulthood. More rarely, it is to be found with lung cancer in the ipsilateral or contralateral lung simultaneously. Case presentation: A 56-year-old man with complaints of intermittent left chest pain for 2 months was referred to our hospital. Chest computed tomography(CT) revealed a cavitary lesion measuring 5.5 cm × 5.7 cm in the superior segment of the left lower lobe. Absence of left pulmonary artery and right-sided aortic arch were found on chest computed tomography angiography (CTA). The tumor was successfully removed via left pneumonectomy, and postoperative histopathology showed that the tumor was a squamous cell carcinoma (T2bN1). At a postoperative 24-month follow-up, the patient was free of disease and no evidence of recurrence or metastasis. Based on literature review, this is the ninth case of lung cancer in UAPA patients. Conclusions: Lung cancer and UAPA occurred ipsilaterally in 66.7% of these cases (6/9), including the present case.

“…Diagnosis of UAPA can be very difficult and should be considered on the basis of medical history, physical examination and imaging studies, including echocardiogram, chest roentgenograms, CT scans, perfusion scintigraphy and angiography (12)(13)(14)(15). The typical findings on CT scans or roentgenograms may include elevation of the ipsilateral hemidiaphragm, a diminished hemithorax, a mosaic attenuation pattern, and displacement of the mediastinum, as well as interruption in the pulmonary artery and loss of normal pulmonary vascular markings (12,(14)(15)(16). However, it should be noted that the affected lung is supplied by the bronchial, diaphragmatic, intercostal, or aortopulmonary collateral arteries that may be visualized on angiogram or echocardiogram (2).…”

Unilateral absence of pulmonary artery associated with contralateral lung cancer

Unilateral absence of a pulmonary artery (UAPA) is a rare congenital cardiac malformation that is often associated with other cardiovascular deformities. Surgical repair of this rare condition is usually performed only on the abnormal lung. The occurrence of lung cancer in association with UAPA is even rarer and clinical experience is very limited. This report aims to describe a case of unilateral absence of right pulmonary artery that was complicated by primary carcinoma of the contralateral lung. A left lower lobectomy was performed despite the absence of the right pulmonary artery and repeated decreases in the arterial oxygen saturation (SaO) were encountered intraoperatively. The current case provides insights into the operative tolerability and the foreseeable ominous prognosis after excision of the normal lung in patients with UAPA and highlights the importance of the clinical awareness of this potentially lethal congenital anomaly in light of its extreme rarity, which may facilitate better diagnosis and treatment of such patients.

“…170 This lesion can be asymptomatic into adulthood. [171][172][173][174] Abnormal arterial supply to the lung segments such as seen in scimitar syndrome with sequestration is also well seen by cardiovascular CT. [175][176][177][178] Cardiovascular CT is the imaging modality of choice to determine anatomic substrate and interventional planning for complex lung lesions such as intralobar or extralobar pulmonary sequestration. 179,180 In a study evaluating the utility of cardiovascular CT for surgical planning in these patients, treatments were correctly planned using cardiovascular CT with 100% accuracy, sensitivity and specificity.…”
