Background:
Lumbar puncture is a well-known procedure. The indications for lumbar puncture vary among different medical and surgical disciplines, though obtaining a sample for cerebrospinal fluid analysis is the most common one. A normal coagulation profile is crucial prior to pursing the procedure. Occasionally, an urgent sample is needed to guide an appropriate treatment while the patient's coagulation status is suboptimum. In those specific critical situations, some may accept suboptimal correction owing to the urgency of the case.
Case Description:
We report a case for a patient with Burkitt lymphoma who presented with mild neuroaxial symptoms. An urgent cerebrospinal fluid sample was required which was taken after correcting his platelets count to 53.4 × 109/L. He developed a massive multi-compartmental thoracolumbar hematoma with acute cauda equine syndrome requiring surgical intervention. Despite aggressive management, he remained permanently paraplegic with functional status that negatively affected his overall outcome.
Conclusion:
Lumbar puncture is a useful diagnostic and treatment tool. Although serious events are seldom, they can be detrimental. A precaution not to underestimate such events in practicing lumbar, especially in patients with suboptimum coagulation state. Image-guided procedure can be useful and should be considered in appropriately selected patients.
