A 46-year-old woman, with biopsy proven pulmonary sarcoidosis, was referred for an [18F]-FDG PET/CT scan that depicted multivisceral involvement and an unusual [18F]-FDG focus located in the pituitary fossa consistent with pituitary sarcoidosis. This was confirmed by decreased antidiuretic hormone blood levels and contrast-enhanced CT scan. This unsuspected neurosarcoidosis prompted corticosteroid therapy. A [18F]-FDG-PET/CT examination performed 10 weeks after initiation of treatment revealed complete recovery. It is suggested that the skull base should be included in the PET scanning of patients with sarcoidosis. [18F]-FDG imaging may be useful in the early evaluation of response to treatment.
一名46岁女性，经活检证实患有肺部结节病，因进行[18F]-FDG PET/CT扫描前来就诊，扫描显示多脏器受累，且垂体窝有一个异常的[18F]-FDG浓聚灶，符合垂体结节病。抗利尿激素血水平降低及增强CT扫描证实了这一点。这种未被怀疑的神经结节病促使进行了皮质类固醇治疗。治疗开始10周后进行的[18F]-FDG-PET/CT检查显示完全恢复。建议结节病患者的PET扫描应包括颅底。[18F]-FDG成像可能有助于早期评估治疗反应。
