“…The common causes of acquired EVPE include compressive lesions in the spinal cord, intracranial hypotension, inferior vena cava or iliac vens thrombosis, and increased intraabdominal pressure (e.g., pregnancy, obesity). 3 Lumbar epidural varices can compress nerve root and thecal sac directly, therefore they clinically and radiologically mimic lumbar disc herniation. 4 Lumbar epidural pressure is related to posture, increased with extension and decreased with flexion.…”

“…Engorgement of the epidural veins can reflect a benign process or an underlying disease. A large pelvic mass, pregnancy, or aplasia of the inferior vena cava can limit venous return of blood from the pelvis, redirecting blood through intervertebral foraminal veins into the plexus . A distended urinary bladder is one reversible cause of pelvic venous compression and lumbar epidural venous plexus engorgement (Fig ) .…”

“…Whether it reflects a benign or pathologic process, an engorged venous plexus can result in symptoms. The engorged veins can narrow the spinal canal, resulting in symptoms associated with spinal stenosis or radiculopathy . Dilation of the lumbar epidural plexus can crowd or compress the cauda equina and cause cauda equina syndrome …”

Variations in the venous drainage of the central nervous system can have imaging and clinical findings that mimic pathology, presenting a challenge for neuroimagers and clinicians. Patients with these variants may undergo unnecessary testing, and patients with pathology may receive delayed diagnoses because of overlap with benign findings. Consequently, the accurate identification of venous variations on cross-sectional imaging and angiography and their potential causes are critical for differentiating benign imaging variants from potential pathologic processes requiring further evaluation. For example, in the epidural space, benign dilation of the epidural venous plexus may be mistaken for evidence of a fistula, abscess, or metastasis. Hypoplasia of a dural venous sinus or an arachnoid granulation may mimic venous sinus thrombosis. The superior ophthalmic vein may demonstrate benign dilation in intubated patients, mimicking thrombosis, increased intracranial pressure, orbital varix, inflammatory pseudotumor, or other conditions. Furthermore, certain venous variations, such as the occipital sinus or emissary veins, may complicate surgery or herald pathology and should be reported. In addition, some supposedly benign variations, such as the developmental venous anomaly, can be complicated by pathology. The objective of this review article is to provide a descriptive and pictorial review of common anatomic and physiologic variations in the venous drainage system of the brain, spine, and orbits that can mimic pathology. Neuroimaging findings of related pathologies and differences in clinical presentations will also be discussed to assist in the approach to differential diagnosis.

Sciatica is generally caused by such well-recognized entity as lumbar disc herniation in neurosurgical practice. However rare pathologies such as epidural varices may mimic them by causing radicular symptoms. In this case report, we present a 20-years-old man with the complaint of low back pain and bilateral sciatica (Lt>Rt) & neurogenic claudication who was operated for right L5–S1 disc herniation. The lesion interpreted as an extruded disc herniation preoperatively on MRI but was found to be an epidural varix compressing the nerve roots intraoperatively. The varicosity of veins was found in epidural space causing canal stenosis.
