MRI findings of minimal deviation adenocarcinoma of cervix / 中华肿瘤杂志

ABSTRACT

Objective@#To investigate the characteristics of magnetic resonance imaging (MRI) of minimal deviation adenocarcinoma (MDA) of cervix, and improve the diagnostic accuracy of MDA.@*Methods@#The imaging data of eight cases of MDA was retrospectively collected, including tumor size, tumor location, tumor components, signal characteristics, enhancement characteristics and invasive extent.@*Results@#The maximum diameter of tumor was (4.36±1.46) cm. Six tumors were mixed solid and cystic and two were predominantly solid. Six were diffusion limited on diffusion-weighted imaging, and two were not diffusion limited. On multi-phase dynamic contrast-enhanced scan, the enhancement curve of solid components of the tumor showed a plateau-like pattern in three cases and a slow-rising pattern in five cases. Tumors were confined to the cervical canal in three cases, infiltrated to cervical stroma > 1/2 depth in seven cases, and ≤ 1/2 depth in one case. There were four cases of uterine invasion, four cases of vaginal fornix invasion, four cases of bilateral ovarian metastasis and one case of lymph node metastasis.@*Conclusions@#Patients suffering from large amount of vaginal discharge had cervical lesions on MRI showing polycystic and solid component enhancement should be alert to MDA. Deep-seated cervical biopsy and even conization is conducive to early diagnosis, treatment and improvement of prognosis.
