2. CT pulmonary angiography shows new consolidation
Axial enhanced CT pulmonary angiography (Figure 9) shows no evidence of acute or chronic pulmonary embolism. Pleural-based lingular consolidation and adjacent nodularity are new from the remote prior CT [and have developed on the most recent chest radiograph] and are consistent with community-acquired pneumonia. While pulmonary nodularity has developed since prior, it is restricted to the area of consolidation, and is not widespread or bilateral. The left lower lobe nodule has enlarged since previous but is not cavitary.
The left lower lobe nodule in 2015 measured an average of 25.85 mm and has increased to an average of 49.95 mm 9 years (3299 days) later, yielding a volume of doubling time of 1325 days.
