Hello letter from my surgeon says an Ill defined isoechoic nodule with hypoechoic foci, anyone know what this means.

Thanx Tracy

You've been given an ultrasound scan of your thyroid. The detector picks up the strength of sound signal that the tissues like the thyroid return to it. The surgeon has found a nodule (lump) in your thyroid that has the same signal return strength as the normal tissue surrounding it - that's why it's ill-defined. But also in the nodule there are areas (foci) where the signal return is weak (hypoechoic). This means that these areas are less dense than their surroundings.
