Cervical epidural hematoma: a case series highlighting uncommon causes.

Abstract

Background: Cervical epidural hematoma (CEH) is a rare but potentially devastating condition, characterized by the accumulation of blood within the epidural space of the cervical spine, leading to spinal cord compression (Perron AD, Huff JS. Spinal cord disorders. In: Marx JA, et al. editors. Rosen's emergency medicine: concepts and clinical practice. 8th ed. Philadelphia: Saunders; 2013. pp. 1419-27.); (Raasck K, Habis AA, Aoude A, Simoes L, Barros F, Reindl R. Spontaneous spinal epidural hematoma management: a case series and literature review.

While trauma and iatrogenic causes are well-documented, cases attributed to neck strain and acupuncture are uncommon. (Raasck K, Habis AA, Aoude A, Simoes L, Barros F, Reindl R.

Neurology. 1979;29(8):1188-90. https://doi.org/10.1212/wnl.29.8.1188 .) Here, we present two cases of CEH secondary to these unusual aetiologies. Both cases highlight the importance of considering uncommon causes of CEH to ensure early recognition and prompt treatment.

Case presentations: Case 1 is an 81-year-old lady who presented with left hemiparesis and paraesthesia following a fall with neck strain. Magnetic resonance imaging (MRI) of cervical spine revealed left C3-C7 epidural haematoma with severe cord compression. In Case 2, a 35-year-old gentleman experienced sudden onset numbness and weakness in all limbs just 10 minutes after receiving acupuncture. MRI showed an epidural hematoma at the C2-C4 levels. Both patients underwent immediate surgical decompression and had significant recovery.

Conclusion: Although CEH is a rare occurrence, it can potentially be a neurosurgical emergency. Physicians must remain cognizant of the diverse aetiologies associated with CEH and the necessity for early recognition and immediate treatment.
