ABSTRACT

Study Design: Case report. Objectives: We report two cases regarding epidural air pseudocyst at the lumbar spine. Summary of Literature Review: Epidural air pseudocyst at the lumbar spine that provokes radiating pain and neurologic symptomscan be misdiagnosed as an epidural tumor or HIVD. Consequently, proper diagnosis and treatment of the epidural air pseudocyst at thelumbar spine is necessary. Materials and Methods: We report on two patients with radiculopathy and neurologic symptoms resulting from epidural airpseudocysts. In one patient, the epidural air pseudocyst was found within the epidural ligament flavum area on an MRI, and fluoroscopicguidedFNA (fine needle aspiration) was performed. In the other, the epidural air pseudocyst was found behind the posterior longitudinalligament and was accompanied by spinal stenosis. In this patient, we conducted open cystectomy and posterior decompression surgery. Results: After treatment, all patients have showed symptom improvement and they are currently living without discomfort. Conclusions: Due to frequent misdiagnosis, the careful diagnosis of lumbar epidural air pseudocyst is necessary. Physicians shouldselect a proper treatment plan concerning the patient’s condition and the location of the lesion.
