ABSTRACT
Objective To summarize the imaging features of esophageal hamartoma.Methods The clinical data of 1 patient with esophageal hamartoma who was admitted to the First Hospital of Jilin University in October 2010 were retrospectively analyzed.The patient received the X-ray barium meal examination,plain and enhanced multi-slice computed tomography (MSCT),esophagoscopy and endoscopic ultrasonography (EUS),and then the imaging features of those were analyzed.The patient underwent endoscopic resection of esophageal hamartoma and postoperative X-ray barium meal reexamination.Results X-ray barium meal examination demonstrated a lobular filling defect and smooth surfaces in the upper third of the esophagus,intact esophageal mucosa with good creeping.MSCT in esophagus showed a lobular soft-tissue density with the uneven inner density and liparod middle density with the size of 4.2 cm × 1.6 cm × 1.5 cm.There was no significant enhancement by enhanced CT scan.The irregular mass of white tumor at insicors 16-23 cm was observed by esophagoscopy,its proximal end was pedunculated and its nodular distally was rough,soft without bleeding and with a luminal stenosis of the local lesions.EUS revealed that there were a heterogeneous and hypoechoic lesion and the rough edge of adventitious coat of esophagus.The patient underwent endoscopic resection of tumor and was confirmed as with esophageal hamartoma by postoperative pathological diagnosis.The patient was followed up for 12 months with a good condition and without tumor recurrence by X-ray barium meal examination.Conclusions Esophageal hamartoma is a rare benign tumor,and its main clinical presentation is chocked fealing when patients take solid food.Enhanced CT scan and EUS are of great significance for the diagnosis of this disease.
