Lobular endocervical glandular hyperplasia (LEGH) is considered as a precursor lesion of cervical adenocarcinomas with poor prognosis, and early diagnosis on MRI is important. MRI of 9 LEGH-associated adenocarcinomas (LEGH-ACs) and 10 LEGHs were retrospectively evaluated. Both LEGH-AC and LEGH appeared as multicystic masses with solid components. 4 of 9 LEGH-ACs (44%) showed diffusion restriction, whereas 5 of 9 LEGH-ACs (56%) and all LEGHs showed no diffusion restriction. On DCE-MRI, 4 of 4 LEGH-ACs (100%) and 2 of 6 LEGHs (33%) showed rapid and prolonged contrast-enhancement pattern, whereas 4 of 6 LEGHs (66%) showed gradual contrast-enhancement pattern suggesting their benignity.
