Ligamentum flavum haematoma: a report of two cases.
We present 2 cases of ligamentum flavum haematoma causing root compression. Magnetic resonance imaging showed an epidural mass linked to the ligamentum flavum. The mass was isointense in T1-weighted images, and was centrally hyperintense and peripherally hypointense in T2-weighted images. Surgical removal of the ligamentum flavum achieved resolution of the symptoms. The definitive diagnosis could only be confirmed by histopathological examinations. The differential diagnoses include lumbar disc herniation and lumbar spinal canal stenosis caused by neoplasm, infection, epidural haematoma, or facet cyst.
