Abstract
The present study reports the case of an adult patient with non-traumatic acute paraplegia following a computed tomography (CT)-guided automated cutting needle biopsy (ACNB). Multiple nodules and masses were revealed on performing chest radiography and CT on a 45‑year‑old man. In order to make a pathological diagnosis, a CT‑guided biopsy using an automatic cutting needle was performed. However, 10 min after the biopsy, a weakness of the lower extremities occurred, and the patient collapsed to the ground, albeit with clear consciousness. Spinal magnetic resonance imaging (MRI) performed subsequently revealed no abnormal findings in the spinal cord. An MRI performed 24 h later, however, revealed swelling of the thoracic spinal cord and a high‑signal‑intensity lesion in T2‑weighted images at the level of T7, T8 and T9. The patient subsequently received hyperbaric oxygen therapy for a few days, and rehabilitative treatment over the course of a few weeks. At 6 months following the biopsy, the patient was unable to walk, although the patient could stand for 10 min and defecate independently. Currently, the patient remains active in daily life, in spite of confinement to a wheelchair. The present case study was reported to raise the awareness of the possibility of spinal cord ischemia and acute paraplegia following a CT‑guided ACNB of the lungs. The mechanism underlying spinal cord ischemia remains to be fully elucidated, although is thought to be multifactorial, involving air embolism.
