MRI shows a small posterior nasopharyngeal lesion iso-intense on T1, heterogenous and with variable hyper-intense signal on T2. Some very thin flow-voids are visible on T2. There is homogeneous enhancement post-gadolinium, with hypervascularisation in the posterior portion of the lesion.
These features are compatible with juvenile angiofibroma, a benign but locally invasive tumor. However, this case is not typical as it doesn't invade the nasal fossae.
