Background: Pneumocephalus can originate from accidental dural puncture while performing epidural block using the loss-of-resistance (LOR) technique with an air-filled syringe. Case: We present two cases of pneumocephalus after lumbar epidural block under fluoroscopy for pain control in elderly patients. Conclusions: Lumbar epidural block should be performed under fluoroscopic guidance in elderly patients with severe lesions. The physician should be aware of the increased possibility of a dural puncture occurring due to anatomical changes in older patients. The use of saline is recommended for the LOR technique. A contrast injection should be used together with the LOR technique to locate the epidural space. If a dural puncture occur, the patient should be carefully monitored to determine whether pneumocephalus has developed.
