Ultrasonography (USG) scan revealed a 40x34x26 mm cystic mass in the left lobe of thyroid gland (Fig. 1).
The cyst is located at the lower part of anterior neck behind the left lobe of the thyroid gland. High-intensity imaging of the content on both T1- (A) and T2- (B and C) weighted MRI suggested that the cyst area was filled with fluid.

High-intensity images on both T1 and T2-weighted magnetic resonance imaging (MRI) suggested that the cystic area was composed of liquid (Fig. 2).
99mTc-MIBI scintigraphy demonstrated focal accumulation and persistent uptake of radiotracers at the wall of the cystic mass. (A and B) Early images of 99mTc-MI; Panels C and D: delayed images of 99mTc-MIBI.

Parathyroid scintigraphy using 99mTc-MIBI showed intense accumulation and persistent uptake of radioactivities by the wall of the cyst (Fig. 3).
