- Oesophageal shiver
Feline oesophagus also known as oesophageal shiver, refers to the transient transverse bands seen in the mid and lower oesophagus on a double-contrast barium swallow.
On this page:
Pathology
The appearance is almost always associated with active gastro-oesophageal reflux 2,3 and is thought to be due to contraction of the muscularis mucosae with resultant shortening of the oesophagus and 'bunching up' of the mucosa in the lumen 2.
Radiographic features
The folds are 1-2 mm thick and run horizontally around the entire circumference of the oesophageal lumen. The findings are transient, seen following reflux and not during swallowing. The appearance is confined to the distal two-thirds of the thoracic oesophagus.
History and etymology
Transverse oesophageal folds were originally described in 1970 by Bremner et al. 5 as a normal anatomic feature of the cat oesophagus. The term feline oesophagus has hence been applied to the similar transient appearance in the human oesophagus.
Differential diagnosis
- scarring from reflux 1,2
- permanent
- thicker
- cross less than half of the lumen
-
oesophageal spasm 1
- much thicker bands
-
eosinophilic oesophagitis 4
- 'ringed oesophagus' seen in ~50%
- similar sized bands
- permanent
- strictures
