Allergic rhinitis is one of the most common causes of nasal obstruction, but other diseases need to be considered particularly when the clinical course is getting worse. We present a patient with known mild persistent allergic rhinitis due to house dust mites who experienced progressive worsening of nasal obstruction with associated hyposmia and mucopurulent discharge. The lack of improvement of the patient’s symptoms prompted the re-evaluation of the case. Skin prick tests for airborne allergens confirmed sensitisation only to house dust mites. Nasal endoscopy and facial CT scan revealed a huge rhinolith occupying almost completely the right nasal cavity. The rhinolith was surgically removed with resolution of symptoms. Rhinoliths are rare and unusual calcified materials which grow around intranasal foreign body; they are often promoted by trauma, surgical operations and dental work. The patient underwent dental work about 30 months before the diagnosis of rhinolith, suggesting a possible aetiology.

Rhinoliths are calcareous concretions that are formed by the deposition of salts on an intranasal foreign body over a number of years. We describe a rare case of rhinolithiasis, whereby a small foreign body has been lodged in a man's nasal cavity for over 80 years. He presented to the ear, nose and throat clinic with a sore throat and an incidental finding of a rhinolith was made which was confirmed by x-ray. This was managed conservatively.

A 34-year-old lady presented with nasal obstruction and sinusitis. She had been having such symptoms for many years despite best medical therapy for several months. Nasal examination revealed a rhinolith in the floor of the nasal cavity with significant rhinitis and mucopus in the middle meatus. After initial examinations were made the pathology of the rhinolith was not clear. CT …

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.

A 20-year-old woman who was fit and well presented with a history of left nasal blockage for 2 years. She was noted on anterior rhinoscopy to have nasal septal deviation towards the left. She was listed for septoplasty with the aim of relieving nasal obstruction. At operation she was found to have a mildly deviated septum to the left. There was also a rhinolith in the left nostril posterior to the deviated septum (figure 1). Following removal of the rhinolith, her nasal airway appeared adequate; hence, septoplasty was not performed. Postoperatively, the patient was pleased with the outcome. When the patient was shown the foreign body she recalled inserting a pen cover into her nose about 10 years previously (figure 2). When she presented to the Accident and Emergency department at that time she was told that there was no foreign body in her nose. Figure 1Endoscopic view of rhinolith. Figure 2Rhinolith.
