Mucinous rectal adenocarcinoma and neoadjuvant therapy: Implications for surgical practice

Figure 3 Pelvic magnetic resonance imaging revealed a local recurrence of mucinous adenocarcinoma 4 years subsequent to an R0 abdominoperineal resection. Sagittal T2-weighted image demonstrated a lobulated, high-signal-intensity mass in the presacral space, consistent with recurrent mucinous disease. The lesion exhibited homogeneous T2 hyperintensity typical of extracellular mucin and ill-defined margins against adjacent pelvic structures. These imaging features are characteristic of mucinous local recurrence and help differentiate it from postoperative seroma or fibrosis.
