Intramural esophageal dissection with eosinophilic esophagitis.

Intramural esophageal dissection (IED), like esophageal perforation, is a rare complication of eosinophilic esophagitis (EoE). A 44-year-old woman who had experienced EoE for 8 years complained of food impaction, severe neck pain, and odynophagia as well as consulted the emergency unit. She was diagnosed with IED with mediastinal emphysema by enhanced computed tomography. After admission, she was treated conservatively with noninvasive treatment, including fasting, intravenous feeding, and antibiotics. Only nine cases of IED with EoE have been previously reported. All were male, and our patient was the first female patient from Asia. Urgent endoscopy was conducted in eight cases, of which three were worse after endoscopy, and in one case, total esophagectomy was conducted due to subsequent esophageal perforation. We did not perform urgent endoscopy on our patient because of a potentially increased risk of esophageal perforation through the procedure. When patients with EoE complain of severe retrosternal pain, odynophagia, or dysphagia, IED should be considered in addition to food impaction.
