Usefulness of the ‘cosmos pattern’ for differentiating between cervical gastric‐type mucin‐positive lesions and other benign cervical cystic lesions in magnetic resonance images

Aim To evaluate the usefulness of the ‘cosmos pattern’ (CP) on magnetic resonance (MR) images for differentiating between gastric‐type mucin‐positive lesions (GMPL) and gastric‐type mucin‐negative lesions (GMNL). Methods This study included 131 patients with clinical suspicion of lobular endocervica...

Description
Summary:Aim To evaluate the usefulness of the ‘cosmos pattern’ (CP) on magnetic resonance (MR) images for differentiating between gastric‐type mucin‐positive lesions (GMPL) and gastric‐type mucin‐negative lesions (GMNL). Methods This study included 131 patients with clinical suspicion of lobular endocervical glandular hyperplasia (LEGH) who underwent pelvic MR imaging and a Pap smear and/or latex agglutination assay. Differences in MR findings, such as cyst and solid component patterns, cervical location and T1‐weighted image (T1WI) signal intensity, were compared between GMPL and GMNL. The diagnostic performances of the findings were assessed. Results The frequencies of CP (63.1%), upper part (UP) lesions (72.3%) and hypointense area compared with the cervical stroma on T1WI (61.3%) were significantly greater in GMPL than in GMNL (P
