We report the case of a 54‑year‑old woman with 3‑year‑history of right facial paralysis. Computed tomography (CT) and magnetic resonance imaging (MRI) findings were highly suggestive of a primary paraganglioma (PGL) of the facial nerve canal (FNC). Ga‑DOTATATE positron emission tomography (PET)/CT confirmed the neuroendocrine nature of the tumor. The combined imaging findings of permeative bone destruction, rapid wash‑in and wash‑out perfusion, and Ga‑DOTATATE tracer uptake in a lesion arising from the mastoid segment of the FNC are diagnostic of a primary PGL of the FNC and may obviate the need for histological confirmation.
我们报告了一例54岁女性，有3年右侧面部麻痹病史。计算机断层扫描（CT）和磁共振成像（MRI）结果高度提示面神经管（FNC）原发性副神经节瘤（PGL）。镓[Ga]‑DOTATATE正电子发射断层扫描（PET）/CT证实了肿瘤的神经内分泌性质。FNC乳突段病变出现的渗透性骨质破坏、快速流入和流出灌注以及镓[Ga]‑DOTATATE示踪剂摄取的综合影像学表现可诊断为FNC原发性PGL，可能无需组织学证实。
