Abstract
Introduction
Ligamentum flavum haematoma (LFH) is an extremely rare entity, found mostly in the lumbar and thoracic ligamentum flavum and seldom in the cervical ligamentum flavum. Cervical LFH can cause paralysis in patients. We describe a case of LFH in the cervical spine that accepted surgical treatment.
Case presentation
A 70-year-old man with incomplete spinal cord injury presented with sudden paralysis of his left limbs for 10 days and hemi-hypaesthesia below the level of the right clavicle. Magnetic resonance imaging (MRI) showed a space-occupying lesion in the left ligamentum flavum between the C4 and C5 laminae. The preliminary diagnoses were concluded to be incomplete spinal cord injury, spinal epidural lesions, and cervical spinal stenosis. After a posterior C3–C6 laminectomy with lateral mass screw instrumentation, the muscle strength and sensation recovered partially. The lesion was greyish black and located in the ligamentum flavum. A pathological examination identified it as a haematoma of the ligamentum flavum. The patient was discharged 15 days after the operation and commenced rehabilitation.
Discussion
The LFH was mainly caused by slight trauma during gentle activities and contributed by many factors. MRI is an essential tool but pathological diagnosis is the gold standard. Most LFH patients can be treated surgically.
