Acute Calcific Discitis or Symptomatic Calcified Schmorl's Node of the Upper Thoracic Spine in an Adult: A Case Report and Literature Review

We describe a patient with acute calcific discitis following symptomatic Schmorl's node (SN) of upper thoracic spine. A 28-year-old female suffered from sudden severe pain in mid-thoracic, left scapular area, radiating to her chest. Plain radiography of the thoracic spine showed calcification in T3–4 intervertebral disc space. Computed tomography (CT) scan and magnetic resonance imaging (MRI) of the spine demonstrated calcification of the T3–T4 nucleus pulposus, migrating into the inferior of T3 vertebral body with reactive bone marrow edema. By conservative treatment with multidrug therapy, the pain subsided and disappeared in 3 months. Follow-up CT scan and MRI of the thoracic spine confirmed complete resolution of calcified SN and reactive bone marrow edema.
