Discussion of Epiglotitis
- Acute epiglottitis is a life-threatening disease
- Usually is bacterial in origin (Haemophilus influenzae). Incidence has decreased secondary to Haemophilus influenzae immunization.
- Peak age is 3.5 years. This is older age group than croup patients.
- Sudden onset with no history of a preceding upper respiratory tract infection.
- Often dysphagia is more pronounced than stridor, and it may be accompanied by high fever and drooling.
- Because of the risk of rapid progression of the condition leading to sudden complete obstruction of the upper airway, radiographs should be obtained expeditiously with minimal manipulation of the neck.
- It is advisable that the examination be performed with portable equipment or that someone capable of intubating the child is available while the child is in the radiology department.
 Imaging Findings for Epiglotitis
- Classic lateral radiographic findings include thickening of the epiglottis and aryepiglottic folds (Thumb sign)
