title: Inflammatory myofibroblastic tumor of the stomach with peritoneal dissemination in a young adult: imaging findings.
abstract: Inflammatory myofibroblastic tumors are lesions that most often affect young adults and children. These tumors have been found in numerous extrapulmonary sites but rarely in the stomach. It is unknown whether this process is reactive or neoplastic. They are infiltrative lesions and often extend through the gastric wall, sometimes reaching adjacent organs including the esophagus, duodenum, peritoneal cavity, spleen. pancreas, and liver. These features mimic malignancy on endoscopy and radiology. We report the ultrasound, color Doppler ultrasound, and helical computed tomographic findings of a gastric inflammatory myofibroblastic tumor with peritoneal dissemination in a young adult. To our knowledge, this is the first report of color Doppler ultrasound and helical computed tomographic findings of this rare disease entity.
