Overview
MRI is usefull diagnostic tool for detecting tumor's spread to lymph nodes or internal organs in pelvic or abdomen, it also has a valuable role in follow-up for the evaluation for tumor recurrence. Findings on MRI of patients with leiomyosarcoma can be heterogenous mass with irregular borders.
MRI
On T1-weighted images of MRI, leiomyosarcomas has the following descriptions:
- large infiltrating myometrial mass of heterogeneous hypointensity with irregular margins.
On T2-weighted images, tumors have the following features:
- Intermediate-to-high signal intensity, with central hyperintensity indicative of extensive necrosis.
- Hemorrhage is common and calcification may be present.[1]
