Abstract and Case Summary

A 48-year-old man presented to the hospital with gross painless hematuria. He underwent a radiologic evaluation, including renal sonography and computed tomography (CT) of the abdomen and pelvis. These studies indicated a solid mass in the mid- to lower-pole of the right kidney. Chest radiographs revealed a right-sided aortic arch, deviation of the trachea to the left, and an abnormal left pulmonary branching pattern.

A 48-year-old man presented to the hospital with gross painless hematuria. He underwent a radiologic evaluation, including renal sonography and computed tomography (CT) of the abdomen and pelvis. These studies indicated a solid mass in the mid- to lower-pole of the right kidney. Chest radiographs revealed a right-sided aortic arch, deviation of the trachea to the left, and an abnormal left pulmonary branching pattern. During his hospital stay, the patient developed shortness of breath and underwent a ventilation-perfusion scan. This revealed absent perfusion of the left lung with diminished ventilation. The study was interpreted as suspicious for a pulmonary embolism to the left pulmonary artery. A contrast-enhanced CT of the chest using a pulmonary embolism protocol was then performed (Figure 1).

Contrast-enhanced CT scan of the chest reveals: (A) a right-sided aortic arch and marked asymmetry of the peripheral pulmonary circulation; (B) absence of the main left pulmonary artery and visualization of bronchial collaterals behind the left main bronchus; and (C) a hypoplastic left lung with unilateral emphysema.
