Ligamentum flavum hematoma is a very rare entity that can occur in any part of the spine. Etiology is still unclear while the minor trauma and ligamentum flavum degeneration are the potential suspects. Patients can present with either radiculopathy or myelopathy according to the location. MRI is the most important tool for the proper diagnosis. The differential diagnosis include juxtafacet cysts, disk herniation and spinal cord tumors. Treatment is usually surgical with favorable surgical outcomes. Ligamentum flavum hematoma should be kept in mind in the differential diagnosis of intraspinal cystic lesions that lead to neurological deficits.
