Abstract
Aim: We describe a 60 year old lady who had a Sylvian fissure lipoma associated with
an underlying middle cerebral artery saccular aneurysm which is a rare association and
describe its imaging features.
Presentation of Case: Due to its rarity and MRI appearances simulating blood products,
this case offered an initial diagnostic dilemma to the reporting radiologists, when an
incidental lesion like lipoma adjoining an aneurysm was initially misinterpreted as blood
products.
Discussion and Conclusion: This case highlights potential pitfalls in imaging
interpretation even with a newer neuroimaging technique to accurately identify the nature
of the lesion that can lead to misdiagnosis with the potential of inappropriate clinical
management, at least in some cases.
