      Hello Stephen,

      I was wondering if you could help me with this case. Patient fell whilst skating 8 days ago and there is a persistent huge bruise over the lateral hip aspect overlying the greater trochanter. Please find included the US findings for this patient. I was wondering how can you differentiate between a haematoma or a Morel Lavallee lesion?

      Kind regards,

      Hi Lena,

      What a classic case,

      I don’t think you can tell the difference between an acute haematoma and a Morel Lavallee lesion at this stage.

      They would look the same,


      With that history of acute shearing trauma and that location over the lateral hip it would be a classic Morel Lavallee lesion.

      I would describe that as an acute haematoma, but given the history and location suggest that a Morel Lavallee lesion may persist.

      The difference will be in the follow up,

      If it is a simple haematoma it will resolve quickly,

      If it is a Morel Lavallee lesion it will persist and be very recalcitrant.

      Now if you ask my opinion as to the most likely outcome I would say with the location and history we will be seeing a Morel Lavallee lesion that will persist !

      Time will tell.

      My worksheet would describe it as an acute haematoma but given the classic location and history of shearing trauma a Morel Lavallee lesion needs to be a serious consideration.

      Please let us know what transpires.

      Happy scanning,
