Abstract
- Objective: To evaluate the diagnostic value of spiral CT and its reconstruction techniques in the diagnosis of extraluminal type gastric stromal tumors.<br />Methods: The data of spiral CT performed 1 week before operation of 17 extraluminal type cases, 11 males and 6 females, aged 35.5 (13-67), from 33 patients of gastric stromal tumors proved by pathology and immunohistochemistry, were analyzed retrospectively.<br />Results: The accuracy rates of level diagnosis and qualitative diagnosis of extraluminal type gastric stromal tumor by spiral CT were 88.2% and 82.4% respectively. The main CT manifestations included: (1) extraluminal mass connected with the gastric wall, with round or lobulated margin and characteristic horn-like appearance and direct invasion, more than 5.0 cm in diameter; (2) inhomogeneous density of mass, including mild to moderate uneven enhancement in artery phase and obvious enhancement in vein and delay phase in 15 cases, and obvious enhancement in artery phase and decrease of enhancement in portal vein phases in 2 cases. (3) Irregular niches and sinus in the margins of the intraluminal masses (n = 11) and unclear border of the masses and invasion into nearby structures (n = 9); (4) connection of the tumor and stomach wall by broad boundary or failure to distinguish the tumor and stomach wall; and (5) invasion to the surrounding tissues and organs as a sign of malignant tumors.<br />Conclusion: Spiral CT and its reconstruction techniques have important value in level diagnosis and qualitative diagnosis of extraluminal type gastric stromal tumors.
