A 53-year-old woman with bilateral proptosis and diffuse lymphadenopathy had FDG PET/CT for the evaluation of lymphoma. There were significant enlargements of the lacrimal glands, thickening of the intraorbital muscles, prominent parotid/submandibular glands, and FDG-avid lymphadenopathy in the neck, right axilla, and mediastinum. The findings were suggestive of either lymphoma or sarcoidosis. Subsequent biopsy of the left lacrimal gland revealed chronic inflammation with lymphoid aggregate formation, atrophy, and fibrosis consistent with chronic sialadenitis, and an incisional biopsy of the cervical lymph node showed salivary gland tissue with inflammation as well. There was no pathological evidence of lymphoma or sarcoidosis.
一位 53 岁的女性患者双侧眼球突出和全身淋巴结肿大，行 FDG PET/CT 检查以评估淋巴瘤。结果显示泪腺明显肿大，眼内肌增厚，腮腺/颌下腺明显突出，颈部、右侧腋窝和纵隔有 FDG 摄取增高的淋巴结肿大。这些发现提示淋巴瘤或结节病。随后对左侧泪腺进行活检，结果显示慢性炎症伴有淋巴样聚集形成、萎缩和纤维化，符合慢性涎腺炎；对颈部淋巴结进行的切开活检显示有炎症的唾液腺组织。没有发现淋巴瘤或结节病的病理证据。
