摘要

對大腸直腸癌的病人而言，產生骨骼肌的轉移是非常罕見的。在此我們報導了一位大腸直腸癌的41歲男性病患，他起初接受了腫瘤的切除手術並被分期爲T3N2M0。在追蹤期間由於腫瘤指數逐漸地上升，但傳統的檢查皆未能發現復發的病灶，因此接受了FDG-PET/CT的全身造影以進一步檢查。FDG-PET/CT在左側臀部的肌肉內發現到一個高度代謝性的病灶，而全身其他部位則沒有異常的發現。手術將這個病灶切除復的病理檢查證實這是一個源自大腸直癌的轉移性腫瘤，在手術之後至今超過10個月的追蹤期間，該病患仍未發現有任何復發或轉移的跡象，因此被認爲是一例十分罕見的以單一臀肌轉移來表現的復發性大腸直腸癌。

It is very rare for patients with colorectal cancer (CRC) to have skeletal muscle metastasis. Here we reported a 41 year-old male with CRC who was initially treated with surgical resection of tumor and was staged as T3N2M0. He was referred for FDG-PET/CT whole-body imaging due to elevating tumor marker but negative traditional work-ups. The FDG-PET/CT imaging localized a solitary hypermetabolic lesion in the muscle of left gluteal area and no other positive finding in the whole body images. Surgical exploration found a hard mass within the left gluteal muscle and pathological examination of the excised tumor approved it to be metastatic adenocarcinoma of colorectal origin. This case was still disease-free in the follow-up periods of more than 10 months and was concluded as a very rare case of recurrent CRC presenting as a solitary metastasis in gluteal muscle.
