ABSTRACT
AIM:
We aimed to identify the radiologic features of uterine cervical adenocarcinoma associated with lobular endocervical glandular hyperplasia (LEGH).METHODS:
We retrospectively analyzed magnetic resonance (MR) images and pathologic findings of eight patients who underwent preoperative MR imaging followed by surgical resection and who were pathologically diagnosed with adenocarcinoma (except for adenocarcinoma in situ) associated with LEGH. We assessed the following MRfindings:
multicystic component (MC), solid component (SC), signal intensity of SC on diffusion-weighted imaging (DWI) and the apparent diffusion coefficient (ADC) map, and radiological stage (r-stage) based on the FIGO classification. A pathologist reevaluated the pathological stage (p-stage) according to the FIGO classification. We correlated the MR findings with the pathologic features.RESULTS:
Eight patients were classified into the following three types based on the MRfindings:
type A, MC and SC; type B, only SC; and type C, only MC. In the five patients with type A, diffusion restriction (DR) was seen on DWI and the ADC map. In 80% of type A cases, the r-stage matched the p-stage. In the one patient with type B, DR was not seen on DWI or the ADC map, and the r-stage matched the p-stage. In the remaining type C cases, DR was not seen on DWI or the ADC map, and the r-stage was underestimated compared with the p-stage.CONCLUSION:
On MR imaging, the most common type of adenocarcinoma with LEGH is type A; type C is difficult to diagnose as carcinoma.Palavras-chave
