Rare giant intradural epidural hemolymphangioma: A case report.

Background: Hemolymphangioma is a rare, noninvasive benign tumor that originates from vascular and lymphatic malformations. It is usually congenital and can present with varying symptoms depending on its location and size. There are very few reports of hemolymphangiomas within the spinal canal, and giant lesions are exceptionally rare.

Case summary: In July 2023, a 64-year-old male with a giant intravertebral epidural hemolymphangioma from thoracic 11 to lumbar 2 (T11-L2) was admitted to the Department of Spine Surgery at the People's Hospital of Binzhou City, China. The patient experienced progressive lumbar and left lower limb pain, numbness, weakness in both lower limbs, and difficulty with urination and defecation. Imaging studies revealed a large cystic mass in the spinal canal at T11-L2. Surgical decompression was performed, and the pathology confirmed hemolymphangioma.

Conclusion: Complete resection of hemolymphangiomas has the best prognosis, and final diagnosis relies on pathologic diagnosis. In this case, the mass was removed intact with a pedicle nail rod system, leading to adequate spinal decompression and restoration of spinal stability.
