Radiological features of adenoid cystic carcinoma of the uterine cervix

Adenoid cystic carcinoma (ACC) of the uterine cervix is a rare primary neoplasm of the uterus that occurs in post-menopausal women; its radiological findings have not been described previously. We present the MR findings of a case of ACC. The mass exhibited homogeneous low-signal intensity on T1-weighted images. On T2-weighted images, the mass showed high-signal intensity with a lobulated contour and multiple septum-like internal architectures. It also contained spots of very high-signal intensity, which would represent the mucin in the glandular lumen. The multiple septum-like internal architectures probably represented interglandular fibrous stroma. These MRI findings may be helpful for future diagnoses of ACC of the uterine cervix.
