Feline Esophagus is
(A) Eosinophilic Esophagitis[?]Feline Oesophagus: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.The appearance is almost always associated with active gastro oesophageal reflux 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. In given image, there are numerous 1-2 mm radiolucent folds across the oesophagus. The folds are angled with respect to the center of the oesophagus in a "herringbone" pattern.The folds occur transiently: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.The appearance is almost always associated with active gastro-oesophageal reflux 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.Radiographic features:The folds are 1-2 mm thick and run horizontally around the entire circumference of the oseophageal 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.Other Options[?]Diffuse Esophageal Spasm:Unknown etiologyNon-progressive dysphagia with solids & liquids & non-exertional chest pain that responds to nitroglycerin.Corkscrew on barium.Diagnosis by Manometry:Periodic occurrence of simultaneous high-amplitude contractions with intervening periods of normal peristalsis.Therapy transplant treatment: Rule out CAD, then medical management of reassurance, nitrates & CCBs.Botulinum toxin injection, surgery does not have an established role.[?]Radiation-Induced Esophagitis:Seen in up to 80% of patients receiving XRT to the chest.Use of cytotoxic chemo has an additive effect.Typically chest pain, dysphagia & odynophagia occur shortly after the initiation of therapy.Late stricture formation is a common complication.Usually self-limited, treatment is symptomatic.[?]Diagnostic Criteria for Eosinophilic Esophagitis:Esophageal dysfunction (clinical symptoms)>15 eosinophils in 1 high power field of 1 or more esophageal specimens.No response to proton pump inhibitor therapy up to 2 mg/kg/day or normal pH monitoring seen in the distal esophagus.
