摘　　要：Ascaris lumbricoides is the largest intestinal nematode parasite of man,which can lead to various complications because of its mobility.As the esophagus is not normal habitat of Ascaris,the report of esophageal ascariasis is rare.An old female presented with dysphagia after an intake of several red bean buns and haw jellies.The barium meal examination revealed a spherical defect in the lower esophagus.Esophageal bezoar or esophageal carcinoma was considered at the beginning.The patient fasted,and received fluid replacement treatment as well as some oral drugs such as proton pump inhibitor and sodium bicarbonate.Then upper gastrointestinal endoscopy was done to further confirm the diagnosis and found a live Ascaris lumbricoides in the gastric antrum and two in the duodenal bulb.The conclusive diagnosis was ascariasis.The esophageal space-occupying lesion might be the entangled worm bolus.Anthelmitnic treatment with mebendazole improved patient's clinical manifestations along with normalization of the radiological findings during a 2-wk follow-up.Authors report herein this rare case of Ascaris lumbricoides in the esophagus,emphasizing the importance of awareness of this parasitic infection as it often presents with different and unspecific symptoms.Ascaris lumbricoides is the largest intestinal nematode parasite of man, which can lead to various complica- tions because of its mobility.
