Abstract:
A case of idiopathic retroperitoneal fibrosis (RF) is reported. MRI showed a low signal intensity on T1 and heterogeneous signal intensity on T2-predominant image. Although this could be demonstrated either in malignant RF or early stage of non-malignant RF, differentiation from malignancy was made from the quick response to steroid therapy.
Insights
Idiopathic retroperitoneal fibrosis (RF) can mimic malignancy on MRI. Early differentiation from malignant conditions is possible through a rapid positive response to steroid therapy, aiding in accurate diagnosis and treatment.
Area of Science:
- Radiology
- Oncology
- Nephrology
Background:
- Idiopathic retroperitoneal fibrosis (RF) is a rare condition characterized by inflammatory tissue in the retroperitoneum.
- Distinguishing benign RF from retroperitoneal malignancy can be challenging based on imaging alone.
