Abstract:
Objective To observe the value of MRI for differentiating flaps and tumor recurrence after tongue cancer reconstruction.Methods Totally 139 patients after flap reconstruction for tongue cancers were retrospectively enrolled,and MRI manifestations of flaps and recurrence of tongue cancer were comparatively analyzed.Results During follow-up,local flaps mainly presented as equal signals on T1WI,high signals on T2WI within 5 months but then predominately as equal signals.Free flaps consistently showed mixed high signals on both T1WI and T2WI,with striated and sheeted muscle signals.The recurrent lesions consistently showed slightly inhomogeneous equal signals on T1WI and high signals on T2WI.The degree of enhancement of flaps gradually decreased,while the recurrent lesions continued to show severe enhancement.The margins of flaps were predominantly indistinct within 5 months after reconstruction,then became distinct in≥13 while＜74 months with smaller size than before,while recurrent lesions continued to show indistinct borders.The mylohyoid muscles and hyoglossus muscles predominantly swelled within 5 months after construction but then atrophied.Hematoma and cyst cavity in the operation area could be observed 5 months after construction.The recurrence lesions located in the lower and posterior junction part of flaps and the residual tongue tissue,spiculated margins could be found in the ipsilateral or contralateral mylohyoid muscles and hyoglossus muscles,as well as cervical lymph node and distant metastases.Conclusion MRI was helpful to differentiating flaps and recurrence lesions after tongue cancer reconstruction.
