Abstract
BACKGROUND

Hepatic hemangiomas can be challenging to diagnose, particularly when they present with atypical features that mimic other conditions, such as gastrointestinal stromal tumors (GISTs). This case highlights the diagnostic difficulties encountered when imaging subepithelial lesions, especially when conventional methods such as computed tomography (CT) and endoscopic ultrasound (EUS) are used.

CASE SUMMARY

A 44-year-old woman presented with intermittent abdominal distension and heartburn for three months. Her medical history included iron deficiency anemia, menorrhagia, and previous cholecystectomy. One week prior to admission, an endoscopy suggested a bulging gastric fundus, which was likely a GIST, along with chronic nonatrophic gastritis and bile reflux. CT and EUS revealed nodules in the gastric fundus, which were initially considered benign tumors with a differential diagnosis of stromal tumor or leiomyoma. During surgery, unexpected lesions were found in the liver pressing against the gastric fundus, leading to laparoscopic liver resection. Postoperative pathology confirmed the diagnosis of hepatic cavernous hemangiomas. The patient recovered well and was discharged five days later, with normal follow-up results at three months.

CONCLUSION

This case underscores the challenges in the preoperative diagnosis of GISTs, particularly the limitations of the use of CT and EUS for the evaluation of subepithelial lesions. While CT is the primary tool for visualizing abdominal tumors, it is difficult to detect smaller lesions and assess the layers of the gastrointestinal wall on CT. EUS is recommended for the evaluation of nodules smaller than 2 cm and is useful for distinguishing GISTs from other lesions; however, its accuracy with regard to the differential diagnosis is relatively low. In this case, the gastric distension observed on imaging led to the compression of a liver tumor against the stomach, resulting in the misinterpretation of the tumor as a gastric wall lesion.

Core Tip: Hepatic hemangiomas can be challenging to diagnose, especially when they mimic other conditions like gastrointestinal stromal tumors. This case highlights the limitations of imaging techniques such as computerized tomography and endoscopic ultrasound in diagnosing subepithelial lesions. While computerized tomography is effective for visualizing abdominal tumors, it struggles to detect smaller lesions and assess the gastrointestinal wall layers. Endoscopic ultrasound is helpful for evaluating smaller nodules, but its diagnostic accuracy is limited. This case emphasizes the importance of considering hepatic lesions when gastrointestinal symptoms are present, particularly when imaging findings are inconclusive.
