Isolated vertebral bone infarction following lumbar artery embolization- a case report

To report a rare case of isolated lumbar vertebral body infarction following lumbar artery embolization for suspected retroperitoneal haemorrhage.

We present the case of a 75-year-old male who underwent lumbar artery embolization due to a suspected retroperitoneal haemorrhage post-surgery. Magnetic resonance imaging (MRI) was performed to monitor post-embolization severe lumbar pain.

Initial MRI two days post-embolization showed no osseous signal changes or epidural abscess. A subsequent MRI 26 days post-embolization was performed because of increasing lumbar back pain and it revealed a new bone infarction at the L3 vertebral body. CT showed embolization deposits within the vertebral body, not present before the procedure.

This unique case underscores the importance of considering vertebral body infarction as a potential complication following lumbar artery embolization. MRI was critical in early detection of the bone infarction, while CT confirmed the presence of embolization material. Awareness of this rare complication is crucial for prompt diagnosis and management.
