Hemangioma of the Esophagus: Endosonographic Imaging and Endoscopic Resection

Abstract

A 49-year-old Japanese man was seen to have an esophageal tumor on a routine barium swallow examination. Endoscopy revealed a sessile polyp covered by an almost normal esophageal mucosa, and the bioptic histology was non-diagnostic. Endoscopic ultrasonography showed a hypoechoic tumor with a diameter of 12 mm, confined to the submucosal layer, with the underlying muscularis propria layer being intact. On the basis of this finding, endoscopic resection was chosen and the tumor was resected using a two-channel endoscope, with prior hypertonic saline and epinephrine injection. The pathologic diagnosis was a cavernous hemangioma of the esophagus.

Accuracy of EUS in the evaluation of small gastric subepithelial lesions

“…Carcinoid tumors larger than 2 cm in maximal cross-sectional dimension on EUS are more likely to be malignant. 18 Pancreatic rests may appear as hypoechoic or mixed echogenicity lesions in the second, third, or fourth layer. 6 Cysts appear as anechoic, rounded or ovoid, compressible structures in the third layer of the GI tract.…”

Efficacy of Endoscopic Mucosal Resection for Management of Small Duodenal Neuroendocrine Tumors

“…1 In addition, the role of endoscopic ultrasound (EUS) in accurately staging duodenal NETs is unclear. 6,7 EUS has frequently been used as an adjunct to EMR to determine depth of invasion for NETs in other parts of the GI tract. In a recent report by Holinga et al, 8 patients who underwent EMR of rectal NETsr10 mm in size were found to have local lymph node metastasis in 9% of cases in the absence of any high-risk histologic features, suggesting that EUS examination pre-EMR may be a critical part of initial evaluation of rectal NETs.…”

Successful en bloc resection of an esophageal hemangioma by endoscopic submucosal dissection

“…Endoscopic ultrasound (EUS) showed a hypoechoic mass localized to the submucosa (• " Fig. 2) [5] and computed tomography (CT) revealed a hyperdense mass that was not invading the surrounding organs. The mass was diagnosed as a submucosal hemangioma of the esophagus.…”
