| Abstract | BACKGROUND CONTEXT: The ligamentum flavum may undergo various pathologic changes, including hypertrophy, calcification, ossification, and cyst formation. Ligamentum flavum hematoma (LFH) is a rare cause of spinal nerve root or cord compression and usually occurs in the lumbar spine. We report a 66-year-old woman with LFH occurring after an epidural block, mimicking epidural hematoma on lumbar spine magnetic resonance imaging (MRI). PURPOSE: To document MRI findings of epidural block-induced LFH mimicking epidural hematoma. STUDY DESIGN/SETTING: A case report. METHODS: A 66-year-old woman presented with a 6-month history of pain in the left buttock and suffered abrupt weakness and numbness in her left leg after an epidural block procedure without any other trauma history. Lumbar spine MRI with enhancement showed a hematoma-like mass in the posterior epidural space at L3-L4 level. RESULTS: The patient underwent a left hemilaminectomy at the L3 level, and a surgeon found a small hematoma between inner and outer walls of ligamentum flavum instead of an epidural hematoma and performed the removal of the hypertrophied ligamentum flavum including the intraligamentary lesion. Histopathologic examination confirmed the lesion as hematoma in the left ligamentum flavum. After surgery, the patient recovered without significant neurologic deficit. CONCLUSIONS: Epidural block-induced LFH can mimic posterior epidural hematoma on MRI. Careful evaluation of hematoma, location, and imaging findings is required for accurate diagnosis. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
