25 year old female slipped and fell on the stairs 1 month ago landing right on her butt! Developed immediate swelling over the top of the right buttock. Swelling progressed and she developed notable bruising over the next 2 weeks. Swelling now improving, but still symptomatic. MRI shows a large fluid collection with muscular disruption, a Morell-Lavallee lesion.
1 month from injury, I thought it would be too clotted. Surprisingly, I was able to aspirate 60cc of fluid. Pain was essentially resolved afterwards. Hopefully, the swelling will not return!
