Ligamentum flavum hematoma in the lumbar spine.
A patient who presented with symptoms suggestive of nerve root compression secondary to an extradural mass was found to have a hematoma in the ligamentum flavum. Pathological examination of surgical specimens revealed an old hemorrhage, and hemosiderin deposits around organized granulation tissue within the ligamentum flavum. Vessels within the ligamentum flavum had, presumably, ruptured during...
متن کاملAn anatomical study of the human lumbar ligamentum flavum.
OBJECTIVE A detailed investigation of the gross and microscopic anatomy of ligamentum flavum. METHODS Material included 14 lumbar vertebral columns obtained from the Anatomy Department, King Faisal University, Dammam during the period between January 2005 and January 2006. Height, width, and thickness of ligamenta flava were measured. A microscopic study was also performed. Computed tomograph...
متن کاملLigamentum flavum hematoma in the lumbar spine mimicking epidural tumor: A case report
Nerve root compression due to ligamentum flavum hematoma is extremely rare, with less than 70 cases reported in the literature. The clinical presentation and images were similar to those of spinal epidural tumors. Herein, we reported a previously healthy 64-year-old female who presented with right radicular leg pain. Neurological examination was consistent with right L5 root compression. The ma...
متن کاملHypertrophy of Ligamentum Flavum in Lumbar Spine Stenosis Is Associated with Increased miR-155 Level
Hypertrophy of ligamentum flavum (LF) contributes to lumbar spinal stenosis (LSS) and is caused mainly by fibrosis. Recent data indicate that miR-155 plays a crucial role in the pathogenesis of different fibrotic diseases. This study aimed to test the hypothesis that miR-155 exerts effects on LF thickness by regulating collagen expression. We found that LF thickness and the expression of collag...
متن کاملLigamentum Flavum Cyst of Lumbar Spine: A Case Report and Literature Review
Ligamentum flavum cysts have rarely been reported and known to be the uncommon cause of spinal compression and radiculopathy. A 63-year-old man presented right sciatica lasting for 1 month. Lumbar computerized tomography and magnetic resonance imaging demonstrated an extradural cystic mass adjacent to the L5-S1 facet joints. Partial hemilaminectomy and flavectomy at the L5-S1 space were perform...
