4. Thoracic CTA shows new upper lobe localized nodular opacities
Thoracic CTA shows no evidence of pulmonary embolism. No recurrence of the bilateral lower lobe pneumonia or nodules is seen, but a small cluster of new nodular opacities is now present within the central anterior segment of the right upper lobe. No other areas of consolidation or new small scattered nodules are evident.
One month later the patient experienced complaints of left eye blurry vision, dizziness, non-focal weakness, which occurred again 8 days later, both episodes resolving within an hour. Brain CT and CTA (not shown) was negative. The patient was then seen again in 8 months when he presented for a routine annual exam, for which no new issues were noted. He then disappeared from follow up for a further 9 months, until he re-presented to his primary care physician for complaints of shortness of breath and constipation for 2-3 weeks’ duration. An ECG and laboratory data, including a complete blood count, BMP, d-dimer, electrolyte panel, TSH, and renal function, were within normal limits. A repeat frontal and lateral chest radiograph (Figure 10) was performed.
