Sciatic nerve compression following bone marrow harvest

We describe a donor who suffered pain secondary to sacral plexus and sciati c nerve compression post bone marrow harvest. Haematoma was demonstrated by magnetic resonance image (MRI) scanning. To our knowledge, this is the fir st reported case of compression neuropathy post bone marrow harvest documen ted by MRI scanning, Given the increasing number of bone marrow transplants being performed and the paramount importance of donor safety, compressive neuropathies need to be remembered as rare but debilitating complications o f bone marrow harvesting. MRI scanning is a useful modality to investigate severe or neuropathic pain post bone marrow harvest.
