Total nodule volume of the mixed cystic-solid nodule, the cystic part and the post-aspirated nodule before and 1 month, 3 months, 6 months and 12 months after interstitial laser photocoagulation (ILP) (median and quartiles). There was a significant decrease in nodule volume from 0 to 3 months (p = 0.0003) and no significant change from 3 months to 12 months (p = 0.65).

Cursors indicate the outer margins of the nodule. Arrow illustrates the position of the fibre in the centre of the nodule just after the fluid has been aspirated. Small arrow illustrates the cyst wall.
