Abstract:

Introduction: Foreign bodies in the external auditory canal are fairly common, and tend to be seeds, toys, or insects. However, foreign bodies in the middle ear are rarer, and are generally accidental or iatrogenic. Although there are numerous reports regarding fascinating foreign bodies in the ear, the same cannot be said about foreign bodies in the Eustachian tube (ET). Case Report: A 20-year-old male patient presented with right-sided active squamosal chronic otitis media (COM) persisting for 10 years. An incidental finding of a hyperintense foreign body (FB) located near the isthmus of the right ET was reported on high-resolution computed tomography (HRCT) of the temporal bones. The FB was bony (eroded incus), which was impacted near the isthmus of the ET and was extremely difficult to remove. A natural FB such as an eroded ossicle in the ET which aggravated the adhesive otitis and caused active squamosal COM has not been reported in the literature. Conclusion: We have reported this case not only for its rarity but also to make readers aware of such incidental findings which can be found only by imaging, and to suggest how they can be tackled with current equipment and technology.

RECENT FINDINGS A clinically useful test for eustachian tube function is still lacking. Narrowing of the isthmus alone was demonstrated to be an insufficient cause of otitis media. Inflammatory mediators identified within the eustachian tube and mi...

Fatal haematemesis due to impacted foreign body in the oesophagus.

Cases of impacted foreign body in the oesophagus are common, but they usually move down the oesophagus into the stomach or are removed at oesophagoscopy. Fatal haematemesis following the ingestion of foreign body is uncommon. We present a case where fatal haematemesis and death occurred after many days of ingestion of the foreign body. It is therefore stressed that prompt removal of impacted fo...
