The inflammatory pseudotumour of the head and neck is a benign lesion, extremely rare outside the cranial orbits. A case is presented of an inflammatory pseudotumour not associated with the IgG4-related disease. The pseudotumour was found as a solitary mass in the infratemporal fossa of a young woman who complained of otalgia and hearing loss. A clear image of the lesion was obtained using an F-fluoro-deoxy-glucose (F-FDG) PET. After the histopathological diagnosis, and treatment with corticosteroids, a second F-FDG PET was performed. The metabolic image had returned to normal, and the previously observed mass disappeared. A brief review is presented of the studies examining this type of lesion.
头颈部炎性假瘤是一种良性病变，在颅眶外极为罕见。本文报告一例与IgG4相关疾病无关的炎性假瘤病例。该假瘤表现为一名主诉耳痛和听力损失的年轻女性颞下窝的孤立性肿块。使用F-氟脱氧葡萄糖（F-FDG）PET获得了病变的清晰图像。经组织病理学诊断并使用皮质类固醇治疗后，进行了第二次F-FDG PET检查。代谢图像已恢复正常，先前观察到的肿块消失。本文对研究此类病变的相关研究进行了简要综述。
