Adrenal schwannoma is a rare adrenal incidentaloma. It is a benign tumor arising from the Schwann cells. Differentiating benign from malignant adrenal lesions requires a combination of clinical, biochemical, imaging, and histopathological findings. 68Ga-DOTANOC PET/CT is one of the sensitive imaging modalities to detect adrenal lesions such as pheochromocytoma. Multiple benign and malignant lesions show somatostatin receptor expression causing a high probability of false-positive findings on somatostatin receptor imaging. We present a case of adrenal incidentaloma positive on 68Ga-DOTANOC PET, which revealed a benign adrenal spindle cell tumor on histopathology.
肾上腺神经鞘瘤是一种罕见的肾上腺偶发瘤。它是一种起源于施万细胞的良性肿瘤。区分良性和恶性肾上腺病变需要结合临床、生化、影像学和组织病理学发现。68Ga-DOTANOC PET/CT 是检测嗜铬细胞瘤等肾上腺病变的敏感影像学方法之一。许多良性和恶性病变都表现出生长抑素受体表达,导致生长抑素受体影像学出现高假阳性率。我们报告了一例 68Ga-DOTANOC PET 阳性的肾上腺偶发瘤病例,其组织病理学显示为良性肾上腺梭形细胞肿瘤。
