Pheochromocytomas are rare tumors which can be malignant in 10% of cases. We present the case of a 75-year-old woman who presented with headache and palpitation for 1 year. She had a past history of right adrenalectomy for pheochromocytoma 20 years back. In between, the patient was asymptomatic. Twenty-four-hour urinary vanillylmandelic acid was raised. Noncontrast CT and ultrasound of abdomen were unremarkable. The patient underwent 68Ga-DOTANOC PET/CT that showed metastasis to left ilium, which was confirmed on biopsy.
嗜铬细胞瘤是一种罕见的肿瘤，其中 10%的病例为恶性肿瘤。我们报告了一位 75 岁女性患者，她因头痛和心悸就诊 1 年。20 年前，她曾因右侧嗜铬细胞瘤接受过肾上腺切除术。在此期间，患者无症状。24 小时尿香草扁桃酸升高。腹部 CT 和超声均未见异常。患者行 68Ga-DOTANOC PET/CT 检查，显示左侧髂骨转移，活检证实了这一结果。
