Patient Data

Age: 40 years
Gender: Female

Diffuse circumferential thickening of the gastric wall extending from the cardia to the antrum, hypodense with no significant enhancement, containing multiple punctate calcifications with partial obliteration of the mucus layer. There is a perigastric fat infiltration with associated ascites (mixed gelatinous/fluid on ultrasound).

Case Discussion

CT features characteristic of mucinous adenocarcinoma of the stomach with most likely pseudomyxoma peritonei.

Gastric mucinous adenocarcinoma is considered as a rare histological subtype of gastric cancer. The extensive thickening of the gastric wall and multiple punctate intratumoral calcifications are the main characteristic features of this tumor.
