The large nodule described previously based on US exhibited a mixed type of calcification; in fact, in the context of a large egg-shell calcification, multiple spots with microcalcifications were observed (Fig. 1A and B). The primary difficulty during the operation was the complete calcification of the entire right lobe, which was adherent to the trachea and vascular structures (Fig. 1A and B).
A. Macroscopically complete calcified nodule. B. Calcified rim when cut.
