Abdominal Wall Seeding of Colorectal Cancer at the Drainage Tube Site Detected by FDG-PET/CT
氟化去氧葡萄糖正子電腦斷層掃描偵測引流管部位產生之大腸直腸癌腹壁轉移
摘要
本文描述一位54歲男性病患，因大腸直腸癌復發接受FDG-PET/CT檢查進行再分期。除了直腸、腹腔與肝臟內的病灶外，在左下腹皮下的部位意外發現一個呈現高代謝活性的微小病灶。左下腹部的理學檢查在先前引流管的結痂組織下方可觸摸到一個結節，與這個高代謝病灶的位置一致。將此病灶切除進行病理切片，證實是源自大腸直腸的轉移性癌，被認定是先前手術進行經皮引流管置放程序所造成腹壁轉移的一種十分罕見的併發症。這個病例顯現了FDG-PET/CT在偵測特殊惡性疾病且產生在預期外部位其強大且獨一無二的效用。
並列摘要
We herein described a 54-year-old male who received FDG-PET/CT imaging for re-staging of recurrent colorectal cancer. Except for the lesions in rectum, peritoneal spaces and liver, a small hypermetabolic lesion was incidentally noted at the subcutaneous area of left lower abdomen. Physical examination revealed a palpable nodule just beneath the scar of previous drainage tube site, consistent with the location of this hypermetabolic nodule. Surgical excision of the lesion was performed and pathology approved it to be metastatic adenocarcinoma of colorectal origin, compatible with a very rare complication of abdominal wall seeding secondary to previous procedure of percutaneous drainage tube placement. This case implicated the powerful and unique utility of FDG-PET/CT to detect a rare malignant process in an unexpected site.
