目的
描述接受原发性头颈部肿瘤切除伴皮瓣重建的患者复发恶性肿瘤的外观。
方法
回顾性分析了25例复发性恶性肿瘤患者的32次检查，26次CT和6次MR扫描。通过活检或疾病进展确认疾病。其中肌皮瓣15例，复合瓣6例，空肠游离移植2例，空肠肌皮瓣联合移植2例。
结果
最常见的复发位置是原发瘤床，涉及重建皮瓣的下表面或缝合线，32次扫描中有14次; 32次扫描中有12次出现淋巴结和皮瓣复发。
结论
当检查皮瓣重建后可能复发的患者时，放射科医生应了解所用皮瓣的类型和预期的外观。在这个病人群体中，肿瘤复发表现为重建皮瓣缝合线处或附近的局灶性复发肿块，或淋巴结疾病，通常在对侧颈部。
PURPOSE
To describe the appearance of recurrent malignant neoplasms in patients who have undergone resection of primary head and neck tumors with flap reconstruction.
METHODS
Thirty-two examinations, 26 CT and 6 MR scans, were retrospectively reviewed in 25 patients with documented recurrent malignant neoplasms. Confirmation of disease was by biopsy or disease progression. The flaps included 15 myocutaneous, 6 free composite, 2 jejunal free grafts, and 2 combined jejunal and myocutaneous flaps.
RESULTS
The most common location of recurrence was in the primary tumor bed involving the undersurface or suture line of the reconstruction flaps, 14 of 32 scans; both nodal and flap recurrence was seen in 12 of 32 scans.
CONCLUSIONS
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.
