title: MR of cystic aberrant cervical thymus.
abstract: The clinical, MR imaging, surgical, and histologic findings in two cases of cystic aberrant cervical thymus were reviewed. Aberrant cervical thymic tissue was sharply circumscribed and extended deep to the posterior pharyngeal wall at the level of the piriform sinus in both cases. Both lesions had cyst contents that were of increased signal intensity on T1-weighted images. Solid components displayed MR signal characteristics identical to normal thymus.
