Abstract
Objective: To realize preoperative diagnosis of uterine adenomatoid tumor (AT).
Subjects: Sixteen cases of AT and 30 randomly selected cases of uterine leiomyoma (LM).
Setting: Takanohara Central Hospital. A referral center of gynecological laparoscopic surgery.
Design: A retrospective comparative study.
Main outcome measure(s): General clinical indices and relative signal intensity (rSI) on MRI images.
Results: No between-group difference was observed with general clinical indices nor with rSI on T1 weighted MRI (rSI/T1). Means of rSI on T2 weighted MRI (rSI/T2) were significantly (p=0.0010) higher in AT than in LM (18.24 ± 9.58 and 6.73 ± 9.10, respectively). Individual rSI/T2 estimates >10 were obtained in the majority (90.9%) of AT group and one third of LM group as well.
Conclusion: Estimation of rSI/T2 could differentiate AT from LM. Accumulation of more cases is, however, essential to draw a more decisive conclusion.
