case_images: Chest X-ray depicted no pathological findings-despite the patient's symptoms
  of cough and hemoptysis.

case_images: Chest X-ray (Figure 1) depicted no pathological findings, whereas laboratory tests (Table 1) revealed neutrophilic leukocytosis [WBC = 13.4 K/muL (normal range: 3.8-10.5 K/muL) - neutrophils = 79.6% (normal range 45%-75%)].
case_images: CT scan of the thorax revealed multiple confluent ground glass and botryoid
  nodules throughout the right lung, but also to a lesser extent in the left
  lung. There is a thickening of the wall of the central bronchi of the right
  lower lobe as well. Based on the reported history, the imaging findings are
  primarily in favor of diffuse alveolar haemorrhage. An incidental finding of
  an aneurysm, maximum diameter 4 cm, was also depicted in the ascending
  aorta, without clinical denotation.

case_images: Computed Tomography (CT) scan of the thorax (Figure 2) revealed multiple bilateral ground glass opacities compatible with alveolar hemorrhage.
case_images: CT scan of the thorax 1 month later revealed resolution of the ground glass
  opacities that had been depicted 1 month ago. The dimensions of the
  ascending aorta were measured the same.

case_images: On the 4th hospitalization day, corticosteroid therapy was tapered to 32 mg of oral methylprednisolone and 7 days later the patient was discharged from the hospital as shown in timeline (Figure 3).
case_images: Symptoms and signs, diagnostic approach, therapeutic intervention, and
  follow-up shown in timeline schedule.

case_images: High resolution chest tomography (HRCT) was performed (Figure 4), which revealed resolution of the ground glass opacities that had been depicted 1 month ago.
