This is a case report of an 80-year-old woman who presented to the ENT services with multiple non-specific upper aerodigestive tract symptoms. Despite extensive investigation and treatment, her symptoms remained unalleviated with significant impact on the psychological morbidity. During a routine flexible nasoendoscopy for worsening globus pharnygis, a mass was noted in the right Rosenmüller's fossa, where the Eustachian tube leaves the lateral wall of the nasopharynx. A CT scan showed this to be a 10 mm calcified entity within the right Eustachian tube. It was subsequently removed under local anaesthesia providing much relief to the patient. Histology showed this mass to be a rhinolith.
