A New Anatomic Variant of T14 Vertebra: A Unique Case Report
Galassi W Mail, Dejarkom C

The most common morphologic design of the spine comprises of 24 presacral mobile segments allocated to 7 non–rib-bearing cervical, 12 ribbearing thoracic, and 5 non-rib-bearing lumbar vertebrae. However, there are significant variations in the number of thoracic and lumbar segments. The authors presented a case of a 65-year-old female with back pain radiating to hips and legs. Plain radiography and magnetic resonance imaging (MRI) of the whole spine revealed fourteen thoracic vertebrae and bilateral ribs, which were found incidentally on preoperative investigation. To the authors’ knowledge, it has never been referenced in the literature.
