Abstract:
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). 68Ga‑DOTATATE positron emission tomography (PET)/CT confirmed the neuroendocrine nature of the tumor. Teaching point: The combined imaging findings of permeative bone destruction, rapid wash‑in and wash‑out perfusion, and 68Ga‑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.

Nerves
The nerve is a bundle of axons that serves as the communication highway in the PNS. Each nerve is ensheathed in a protective layer of connective tissue called the epineurium. This outermost layer safeguards the nerve and supports...
