Aganglionic GE junction / Achalasia Cardia

Marked dilatation of the entire course of thoracic esophagus demonstrating intraluminal fluid status with air fluid levels and smooth distal tapering at the terminal esophagus and gastroesophageal junction level (Rat tail sign) – *likely related to Aganglionic GE junction / Achalasia Cardia*.

*Segmental underdistention of the terminal esophagus and gastroesophageal junction with mild apparent thickening of the esophageal wall, which is likely related to underdistention or spastic distal esophageal contraction- however endoscopic evaluation is recommended to rule out early neoplastic etiology*.

No evidence of aspiration pneumonia. No significant mediastinal lymphadenopathy.
