title: [Cervical ectopic thymus].
abstract: Two cases of cervical aberrant thymus in infants are reported; it's important to identify such ectopia because thymic tissue involutes spontaneously later on; neither surgery nor other treatment is needed. Ultrasonography is a method of choice for tissue characterization of ectopic thymus and differential diagnosis with other cervical masses.
