The day before presentation, the patient had developed a cough productive of green-brown sputa and increasing dyspnoea. On clinical examination, a tachypnoeic patient with bibasal crepitations on lung auscultation and without fever was observed. Arterial blood analysis showed an arterial oxygen tension (Pa,O2) of 8.71 kPa and an arterial carbon dioxide tension (Pa,CO2) of 5.32 kPa.Fig. 1— Case 1. Thoracic computed tomographic section through the central pulmonary arteries: a) without and b) with contrast medium injection. Case 2 A 66-yr-old female, with a history of chronic obstructive pulmonary disease (COPD), presented with dyspnoea on exertion and anorexia, which had been present for 4 months (fig. 2⇓). Four days prior to presentation, the dyspnoea had increased, and she was coughing up mucoid sputa. On clinical examination, a normopnoeic patient with diffuse wheezing and rhonchi but no fever was observed. Arterial blood analysis showed a Pa,O2 of 10.79 kPa and a Pa,CO2 of 4.44 kPa. Spirometric results were obstructive (vital capacity: 2.39 L (88% predicted); forced expiratory volume in one second: 2.27 L (72% pred)) and the transfer factor of the lung for carbon monoxide was reduced (to 4.6 mmoL·min−1·kPa−1 (62% pred)).Fig. 2— Case 2. Plain chest radiograph. Both patients had undergone a surgical procedure a few months prior to these findings. BEFORE TURNING THE PAGE, INTERPRET THE RADIOGRAPHS AND SUGGEST A DIAGNOSIS. … ER -
