摘要


一位32歲的男性因為二個月以來上腹部持續的鈍痛,餐後嘔吐,體重減輕以及便秘,而去就診,在外院做的腹部電腦斷層發現近端空腸壁較厚,而且腫瘤指標CA19-9也上升至800 ng/mL,故懷疑有惡性腫瘤的可能。至本院做了正子造影後在左上腹部發現一個病灶對FDG的攝取量增加,小腸內視鏡也發現空腸的黏膜層增厚且有跳躍性的病灶。切片組識的培養顯示為結核病。進一步的評估並未發現患者有肺結核的情形。

A 32-year-old male had suffered from persistent dull epigastric pain, constipation, postprandial vomiting, and body-weight loss for 2 months. An abdominal computed tomography (CT) scan showed thickening of the proximal jejunal wall. He was also referred to our center for an fluoro-2-deoxy-D-glucose–positron emission tomography (FDG-PET) scan because his tumor marker CA19-9 was above 800 ng/mL and malignancy was suspected. The PET scan showed an FDG-avid lesion over the upper left abdomen. Endoscopy of the small intestine revealed focal thickening of the mucosal fold and skip ulcer lesions in the jejunum. Culture from the biopsy tissue proved the diagnosis of Mycobacterium tuberculosis infection. No evidence of pulmonary tuberculosis was detected during further evaluation.
