CT of gastric masses: Image patterns and a note on potential pitfalls

摘要: Computed tomography (CT) was performed in 9 consecutive cases of primary gastric neoplasm. Lesions were surgically or endoscopically proved; cross-sectional images are correlated to specific histopathology each case. The CT leiomyoma and leiomyoblastoma characterized as models pure bulging intramural growth resulting a lunate contrast distribution when imaged the plane. In 5 lymphoma, distortion contrast-filled hollow viscus is relatively consistent. Nodular reflected on image series digitations encroaching opacified portion lumen. Image pattern recognition, relative histopathology, more than academic interest since endoscopy frequently unreliable submucosal exophytic pathology. Further, biopsy such lesions commonly non-diagnostic result random choice site inadequate depth tissue sample.
