Overview
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, and no enhancement or mild rim enhancement on contrast T1 signal.[1][2]
MRI
- MRI is helpful in the diagnosis of dermoid cyst. Findings on MRI suggestive of dermoid cyst include:[1][2]
- 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
