Case Report

We present the case of a 70-year-old woman with no relevant history to whom an upper endoscopy was performed due to dyspeptic complaints. During the examination, an apparent subepithelial lesion with approximately 30 mm located in the gastric fundus was observed.

For additional assessment, we performed a hydrogastric sonography (HGS). The examination was executed after the ingestion of 400 mL of water. HGS demonstrated a hyperechoic nodule located in the periphery of the left hepatic lobe with 27 mm of bigger axis, compatible with an hepatic hemangioma. As the lesion was exophytic, it compressed the stomach wall, mimicking a subepithelial lesion.

Hepatic hemangiomas are the most common liver benign tumors, typically presenting as a homogenous, hyperechoic nodule with well-defined margins on ultrasonography. Exophytic forms of hepatic hemangiomas are very rare . Endoscopic ultrasound (EUS) is currently the gold standard in the evaluation of subepithelial lesions of the gastrointestinal tract, allowing the differentiation of extramural compression from intramural growth, the determination of layer of origin, regional lymphadenopathy and the acquisition of tissue for anatomopathologic diagnosis . However, EUS is an invasive procedure with a risk of complications. HGS is a modification of transabdominal ultrasound, with the advantages of being widely available, non-invasive and with no major costs when compared with EUS. This case adds to the existing evidence of the value of HGS in the diagnosis of submucosal lesions and extrinsic compressions of the gastric wall .
