Abstract
BACKGROUND
Ligamentum flavum hematoma (LFH) can cause compression of the spinal cord or nerve root, which results in neurological symptoms. We report a case of lumbar radicular pain due to LFH following a traffic accident.
CASE SUMMARY
A 59-year-old man complained of left buttock and lateral thigh pain that was dull in nature after a traffic accident 18 d prior to presentation. Magnetic resonance imaging (MRI), taken 17 d after the traffic accident, revealed a mass lesion at the L4-5 Level. These MRI findings suggested subacute LFH. The patient’s pain was not alleviated with conservative treatment, including oral medication and epidural steroid injection. After a partial-hemilaminectomy and removal of LFH, the patient’s pain completely disappeared.
CONCLUSION
Because early operation for decompression is important for a good outcome, clinicians should be able to determine LFH from MRI results and be aware of the possibility of LFH, especially in patients with a history of trauma.
Core Tip: Magnetic resonance imaging is the method of choice for diagnosis of ligamentum flavum hematoma (LFH). In the acute stage of LFH, the hematoma appears hypointense in T2-weighted images and isointense in T1-weighted images. Between 3 and 7 d of LFH, the methemoglobin causes the hematoma to be hyperintense in T1-weighted images. At 1 wk after the onset, the hemolysis of erythrocytes results in the accumulation of extracellular meta-hemoglobin, which appears hyperintense in T1-weighted and T2-weighted images. Also, clinicians should be aware of the possibility of LFH, especially in patients with a history of trauma.
