Abstract

The objective of this study is to present a rare case of an invaginated inferior vena cava (IVC) aneurysm in the lumbar intradiscal space. A 73-year-old woman with lower back pain and bilateral lower extremity swelling presented to the clinic. She had undergone spinal surgery performed thrice at the same site (L4–L5) in another hospital and a separate posterolateral fusion surgery procedure 3 years previously. On plain radiography, pseudarthrosis was observed at L4–L5 segment. Contrast computed tomography (CT) imaging revealed a dilatation of the IVC in the intradiscal space of L4–L5. On the anterior side, anterior discectomy was performed. Following insertion of the allograft bone chip and cage, the invaginated IVC aneurysm was repositioned. Implant removal and screw fixation were performed posteriorly. Post-surgery, the patient’s lower back pain improved, and the start of anticoagulation treatment after vascular evaluation was planned. Although there have been numerous case reports of patients with intradiscal cysts or gas requiring surgical treatment, there have not yet been any reports of those with invaginated IVC in an intradiscal space. It is important to provide the appropriate treatment based on a thorough prior understanding of the patient’s anatomy.
