Objective: The purpose of this article is to illustrate the common locations of desmoid tumors (deep fibromatosis), complications of intra- and extraabdominal desmoids, and treatment-related changes in their imaging appearance.
Conclusion: Desmoids are locally aggressive fibrous tumors with a tendency to recur. Desmoids can be intraabdominal, in the abdominal wall, or extraabdominal. Complications, such as compression or invasion of adjacent structures, and abscess formation can occur. Treatment options include observation, local treatment (surgery, radiotherapy), or systemic therapy (conventional chemotherapy, molecular targeted agents).
