Long-term ultrasound follow-up of thyroid colloid cysts.

Kim DW - Int J Endocrinol (2014)

Bottom Line: Through long-term US follow-up, the interval changes for TCCs were classified as follows: no interval change (n = 8), gradual increase (n = 8), gradual decrease (n = 5), positive fluctuation (n = 3), negative fluctuation (n = 6), disappearance (n = 5), and new detection (n = 6).Conclusions.In this study, TCCs demonstrated various interval changes, but no abrupt increase was found or acute onset of symptoms occurred.

ABSTRACT
Objective. This study aimed to assess the interval changes of thyroid colloid cysts (TCCs) by performing long-term ultrasound (US) follow-up examinations. Methods. From 2007 to 2008, 437 patients underwent a lobectomy for the treatment of papillary thyroid microcarcinoma. Among them, 268 patients underwent 4 or more postoperative US follow-ups after surgery. This study investigated the prevalence and interval changes of TCCs ≥3 mm by using US follow-ups. Results. Among 268 patients, 35 (13.1%) had TCCs ≥3 mm by a preoperative thyroid US, and 6 (2.2%) had newly detected TCCs at a US follow-up. Through long-term US follow-up, the interval changes for TCCs were classified as follows: no interval change (n = 8), gradual increase (n = 8), gradual decrease (n = 5), positive fluctuation (n = 3), negative fluctuation (n = 6), disappearance (n = 5), and new detection (n = 6). None of the TCC cases had a TCC that was ≥10 mm at its largest diameter, and no patient complained of any relevant symptoms pertaining to the TCCs. Conclusions. In this study, TCCs demonstrated various interval changes, but no abrupt increase was found or acute onset of symptoms occurred.

A 27-year-old woman with gradual increase in a thyroid colloid cyst. Preoperative longitudinal sonogram (a) shows a colloid cyst with an anechoic nodule and a comet-tail artifact in the left thyroid lobe (arrow, 3.2 mm at its largest diameter). Upon sequential US follow-ups, this colloid cyst demonstrates a gradual increase at a 1-year (b) (arrow, 3.5 mm at its largest diameter), a 3-year (c) (arrow, 4.7 mm at its largest diameter), and a 5-year (d) (arrow, 5.1 mm at its largest diameter) postlobectomy.

Mentions: Of the 437 patients, 268 patients (61.3%) underwent a long-term follow-up with US examinations (range 60–78 months; mean 65.7 months). Of the 268 patients, 41 patients (15.3%; 32 women and 9 men; range 24–66 years; mean age 42.2 years) had TCCs ≥ 3 mm at the largest diameter of the TCCs (range 3.0–8.2 mm; mean 3.9 mm). Among them, 35 patients (13.1%) had TCCs during both the preoperative thyroid US examination and US follow-ups; however, 6 patients (2.2%) had TCCs only during the US follow-ups. Through the preoperative thyroid US examinations and US follow-ups, the interval change for the TCCs was classified as follows: no interval change (n = 8), gradual increase (n = 8) (Figure 1), gradual decrease (n = 5), positive fluctuation (n = 3), negative fluctuation (n = 6), disappearance (n = 5), and new detection (n = 6). The sonographic results for a total of 41 TCCs are summarized in Table 1.
