Findings: A well-defined mass measuring 4.9 x 5.8 cm is seen adjacent to the pyloric antrum. Multiple small hypodensities/cystic areas are seen in it. No calcifications or septations are seen in it. It shows moderate enhancement on post-contrast images. A well-defined hypodense lesion measuring approximately 11 x 15 mm is seen in the right hepatic lobe which is likely a hepatic cyst or hemangioma. A note is made of hypertrophy of the caudate lobe with normal hepatic veins and IVC. No significant abdominopelvic lymphadenopathy is seen.
Conclusion: Well-defined enhancing soft tissue mass adjacent to the pylorus, which is likely a gastric stromal tumor (GIST); other possible differential diagnosis includes leiomyoma, and neurofibroma.
