Overview
MRI
- MRI is helpful in the diagnosis of dermoid cyst. Findings on MRI suggestive of dermoid cyst include:
- Hypointense (due to the water content) or hyperintense (due to the presence of fatty secretions of sebaceous glands) T1 signal
- Hyperintense T2 signal
- No enhancement or mild rim enhancement on contrast T1 signal
