Detailed Answer:
Hello
Thanks for writing to XXXXXXX

Ultrasound differentiates lesions by echogenesity.
Small Isoechoic(Iso means same echogenesity to neighbouring structure) lesions in GB neck region may be most likely poyp.Other causes may be metastasis in wall of GB or intraluminal mass.
Metastatic lesions (generally from melanoma) to wall of GB may have variety of appearance from hypoechoic to isoechoic.
Intraluminal mass may also be iso,hyper or hypoechoic.Intra luminal mass is confirmed by changing the position of patient. Mass moves with position.
Lesions smaller than 1 cm are generally benign whereas chances of malignancy is more in lesions greater than one cm. It is just rough estimate. It has to be confirmed by other means.

Most likely small lesion in your case is polyp. These are generally asymptomatic and chances of its occurrance increases with age and association with calculus.
You need follow-up ultrasound for your lesion and clinical correlation.

Hope I have answered your query.
Further query is most welcome.
Get well soon.
