Thoracic disk herniation manifesting as sciatica-like pain

Two patients presented with sciatica-like pain caused by thoracic disk herniation. Sciatica-like pain was the initial and major symptom in both patients, but careful neurological examination showed vague signs of upper motor neuron disturbance, and thoracic magnetic resonance (MR) imaging revealed disk herniations at the mid-thoracic level. After video-assisted thoracoscopic discectomy, the pain was completely improved. Thorough neurological examination and MR imagery of the thoracic spine, and if needed, even the cervical spine, are required if lumbar image findings do not correlate with the symptoms or physical examination.
