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.
背景
黄韧带血肿（LFH）可导致脊髓或神经根受压，从而引起神经症状。我们报告1例交通事故后因LFH导致的腰神经根性疼痛病例。
病例摘要
一名59岁男性，在就诊前18天发生交通事故后，主诉左臀部和大腿外侧钝痛。交通事故后17天进行的磁共振成像（MRI）显示L4 - 5水平有一个肿块病变。这些MRI表现提示亚急性LFH。包括口服药物和硬膜外类固醇注射在内的保守治疗未能缓解患者的疼痛。在进行部分半椎板切除术并切除LFH后，患者的疼痛完全消失。
结论
由于早期减压手术对于获得良好预后很重要，临床医生应能够根据MRI结果判断LFH，并意识到LFH的可能性，尤其是对于有创伤史的患者。
