# Typical Imaging Features of Perianal Mucinous Adenocarcinoma **Authors:** Hyeji Kim, Seung Soo Kim, Dong Hyun Kang PMC · DOI: 10.5334/jbsr.4095 · Journal of the Belgian Society of Radiology · 2026-02-19 ## TL;DR This paper describes the typical imaging features of perianal mucinous adenocarcinoma, helping in its accurate diagnosis. ## Contribution The study identifies specific imaging characteristics unique to perianal mucinous adenocarcinoma. ## Key findings - The tumor appears as a multilocular cystic mass around the anus. - It shows peripheral irregular enhancement and calcification on imaging. - It has slightly higher signal intensity than muscle on T1-weighted imaging. ## Abstract Teaching point: Typical imaging features of perianal mucinous adenocarcinoma are multilocular cystic mass around the anus, with peripheral irregular enhancement, calcification, and slightly higher signal intensity than muscle on T1-weighted imaging. ## Full-text entities - **Genes:** CRP (C-reactive protein) [NCBI Gene 1401] {aka PTX1}, mucin [NCBI Gene 100508689] - **Diseases:** pseudomyxoma (MESH:D011553), sacrococcygeal teratoma (MESH:D013724), Mucinous adenocarcinoma (MESH:D002288), neoplasms of the gastrointestinal tract (MESH:D005770), gut cyst (MESH:D003560), painful (MESH:D010146), perianal abscess (MESH:D000038), calcification (MESH:D002114), malignant neoplasm (MESH:D009369), anal carcinomas (MESH:D001005), perianal mass (MESH:C536030) - **Chemicals:** carbohydrate antigen (-), Fluorodeoxyglucose (MESH:D019788), gadolinium (MESH:D005682) - **Species:** Homo sapiens (human, species) [taxon 9606] ## Full text _Full body text omitted from this summary view._ Fetch the complete paper as Markdown: https://tomesphere.com/paper/PMC12922680/full.md ## Figures 3 figures with captions in the complete paper: https://tomesphere.com/paper/PMC12922680/full.md ## References 1 references — full list in the complete paper: https://tomesphere.com/paper/PMC12922680/full.md --- Source: https://tomesphere.com/paper/PMC12922680
