Objective:

To analyze the CT features of leiomyoma of gastric cardiac

and to improve the diagnostic level.

Methods:

The CT features of 16 patients with pathology-proven leiomyomas of gastric cardia were retrospectively reviewed. All 16 patients underwent non-enhanced and contrast-enhanced CT in arterial phase and portal phase.

Results:

The leiomyomas showed well-defined solid masses

with endoluminal (

n

=7)

mixed (

n

=6) or extraluminal (

n

=3) growth patterns. There were 4 contours: irregular (

n

=6)

circular (

n

=5)

f

lattened (

n

=3) or lobulated (

n

=2). The mean CT values were 42.3 HU (plain scan)

49.0 HU (arterial phase)

and 56.6 HU (portal phase)

respectively. In portal phase

mild enhancement was found in 3 cases and moderate enhancement in 13 cases. Six cases had ulceration and 6 cases had perigastric lymph node enlargement.

Conclusion:

CT multi-planar reconstruction which is beneficial to reveal the diverse contour of leiomyoma of gastric cardiac

combined with CT enhanced features is helpful for preoperative diagnosis.
