In the original article an error occurred with the ellipsoid volume formula and subsequently there were errors in Table 2. The volume was calculated using formula V = 4/3*(height*width*length) whereas the correct formula is: V = 4/3*(height/2*width/2*length/2). Therefore, the results reported in Table 2 are 8 times bigger than the actual volume. The corrected Table 2 appears below.
Table 2.
Quantitative features of the lesions, classified based on cytological or histological examination, are reported as medians along with the first and third quartile values and the p-value.
