The sonographic findings of ectopic thymus were similar to those of the thymus; therefore, ...

Of these defects, incomplete migration resulting in ectopic thyroid tissue is the most common (up to 80%). Germinal mutations in the thyroid-related transcription factors NKX2.1, FOXE1, PAX-8, and NKX2.5 h...
