CT and MR appearance of recurrent malignant head and neck neoplasms after resection and flap reconstruction.

Abstract

When examining patients who may have recurrent disease after flap reconstruction, the radiologist should be aware of the type of flap used and the expected appearance. Tumor recurrence in this patient population is manifest either as a focal recurrent mass at or near the suture line of the reconstruction flap, or nodal disease, usually in the contralateral neck.
