摘要

To the Editor: Lumber puncture (LP) is a common procedure performed in childhood hematologic malignancies for therapeutic and diagnostic purposes. Common complications following LP include headache, backache, cerebellar hemiation, trauma to conus medullaris, and iatrogenic meningitis. Bleeding in subdural, epidural, and subarachnoid spaces following LP are well-recognized sites of bleeding [1,2] and occasionally intracranial hemorrhage [3] may also be seen. Hematomyelia (intramedullary spinal cord hemorrhage) is an uncommon cause of myelopathy and can be acute, subacute, or chronic.An 11-year-old male with B-precursor acute lymphoblastic leukemia (ALL) underwent diagnostic LP with a 22-gauge spinal needle at L4/L5 intervertebral space following which clear cerebrospinal fluid (CSF) was obtained. During the procedure, patient complained of weakness in lower limbs and within few seconds he became completely paraplegic with urinary retention and a sensory level corresponding to D12-L1 dermatome. Magnetic resonance imaging (MRI) showed signal alteration in spinal cord extending from D11 to L1 level suggestive of hematomyelia and subarachnoid hemorrhage at L1-L2 level (Fig. 1A,B).
