Posterior epidural migration of a sequestrated lumbar disk fragment: MR imaging findings.
نویسندگان
چکیده
We present a 75-year-old man who, for 2 weeks, had progressive pain in both of his thighs when standing straight. MR imaging showed a sequestrated disk fragment, which had a signal intensity similar to that of a herniated disk with a rim enhancement in the posterior epidural space and a ruptured outermost annulus of the intervertebral disk at L2-3. Awareness of these MR imaging findings can help in the diagnosis of posterior epidural disk migration.

Posterior epidural migration of lumbar disk fragments: report of two cases and review of the literature.
BACKGROUND Posterior epidural migration of an extruded disk fragment is rare, and posterior migration of the free fragments causing cauda equina syndrome is exceptionally rare. The disk fragment must transgress through numerous anatomical restraints including the nerve roots in such cases. METHODS Two cases of migration of the sequestrated disk into the posterior epidural space are presented....
متن کاملPosterior Epidural Herniation of a Lumbar Disk Fragment at L2–3 That Mimicked an Epidural Hematoma
Lumbar disk herniation is common. Because of the posterior longitudinal ligament, migration usually occurs into the ventral epidural space. Rarely, fragments migrate into the dorsal epidural space. A 57-year-old man presented with lower back pain and weakness on right hip flexion and right knee flexion. He had lower back pain 1 day previously and received a transforaminal epidural block at a lo...
متن کاملHuge Sequestered Spinal Disc Mimicking Spinal Intradural Tumor
Background and Importance: Disk sequestration can be defined as a herniated disk with perforation of the fibrous ring (or outermost annulus fibrosus) and posterior longitudinal ligament with migration of the disk fragment to the epidural space. Even after the introduction of high-resolution magnetic resonance imaging (MRI), it is still frequently misinterpreted as neoplastic masses. U...
متن کاملPosterior Epidural Migration of a Sequestrated Lumbar Disk Fragment Causing Cauda Equina Syndrome in an Old Patient: A Case Report
Disk fragment relocation is commonly limited to the anterior epidural space, although posterior epidural movement of a sequestrated disk piece to the posterior epidural space is infrequent. We present an uncommon case of dorsal extradural sequestration of lumbar disk herniation. A 77-year-old man presented with severe leg pain, low back pain, and urinary incontinence. Deep tendon reflexes were ...
متن کاملVoluminous free disk fragment mimicking an extradural tumor.
A 56-year-old man presented with a rare case of a voluminous herniated disc fragment mimicking an intraspinal extradural tumor on magnetic resonance (MR) imaging. He had experienced low back pain and sciatica in his right leg for 12 months, which exacerbated suddenly 4 days before admission accompanied by right quadriceps muscle weakness. MR imaging with gadolinium demonstrated a tumor-like lon...
