Summary

A rare case of cricoid cartilage ossification mimicked a foreign body in a 54-year-old man presenting with severe throat pain. Imaging revealed calcification, not an ingested object, leading to successful treatment.

Background:

Severe throat pain and airway compromise can be caused by foreign bodies.
Subglottic narrowing on imaging necessitates differential diagnosis.

Observation:

A 54-year-old man presented with severe throat pain and signs of subglottic edema.
Fiber-optic endoscopy revealed a narrowed subglottic space.
Radiography showed a dense linear opacity at the cricoid cartilage level.

Findings:

Computed tomography (CT) scan excluded a foreign body, revealing a calcified ridge on the cricoid lamina.
The patient improved with antibiotics and steroids, and gastrointestinal endoscopy was negative for foreign bodies.
This case represents vertical ossification of the cricoid lamina mimicking a foreign body.

Implications:

Cricoid cartilage ossification is a rare condition that can present as a foreign body.
Accurate radiological assessment, including CT, is crucial for differentiating ossification from foreign bodies.
Understanding this rare entity aids in appropriate clinical management and avoids unnecessary interventions.
