Overview

MRI may be helpful in the diagnosis of fibroma. On MRI, fibromas appear isointense or hypointense on T1 sequences and hyperintense on T2 sequences.

MRI Findings

MRI component	Features
T1	Fibromas usually demonstrate homogeneous low signal intensity
T2	Fibromas appear as well-circumscribed masses with low signal intensity May contain scattered hyperintense areas representing oedema or cystic degeneration A band of T2 hypointensity separating the tumour from the uterus on all imaging planes is also considered a characteristic feature
T1 contrast + gadolinium	Usually shows heterogenous enhancement
