Spinal tuberculosis or Pott’s disease is the most common bone manifestation of the disease, characterized by rapid vertebral destruction and spinal deformity. Clinical and radiological ndings are not always su cient to di erentiate the disease from other comorbidities, such as neoplasms. The objective of this study is to report a case treated at a tertiary hospital in Porto Alegre of an 8-year-old female patient who presented with pain in the thoracic spine, gait alteration and weakness in the lower limbs for 1 week. Magnetic resonance imaging of the entire spine presents an expansive solid lesion with destruction of the T8 vertebral body with a reduction of the vertebral canal around 80%, with consequent severe kyphosis of the thoracic spine. The patient underwent surgery with a posterior approach, in which decompression was performed by laminectomy and xation from T6 to T10. Anatomopathological examination con rmed the diagnosis of tuberculosis. The patient evolved well in the postoperative period and, one year later, presented resolution of neurological de cits, cure of tuberculosis and regression of the lesion. The authors report a case of Pott’s disease, diagnosed a er surgery, in which a radical and early surgical approach was essential to obtain the best possible prognosis.
