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.

Granulocytic sarcoma with long spinal cord compression:A case report

BACKGROUND As an extramedullary form of proliferating myeloblasts,granulocytic sarcoma(GS)is common in patients with acute myeloid leukemia.GS in the central nervous system is rare,and an intraspinal space-occupying lesion caused by GS is even rarer.Surgical decompression is often necessary to remove the intraspinal space-occupying lesion.To the best of our knowledge,we report,for the first time a case of GS that caused extensive compression in the spinal canal without surgical decompression treatment.CASE SUMMARY A 15-year-old male suddenly developed numbness and weakness in his lower limbs for 10 d,which affected his walking ability.Acute myeloid leukemia was later diagnosed in the Department of Hematology.Magnetic resonance imaging revealed that multiple segmental space-occupying lesions were causing severe spinal cord compression in the thoracic spinal canal.As a result,the patient received routine chemotherapy before surgery.Interestingly,the intraspinal space-occupying lesions completely diminished on magnetic resonance imaging after a course of chemotherapy,and the sensation and strength in his lower limbs markedly recovered.CONCLUSION An intraspinal space-occupying lesion could be the first symptom of acute myeloid leukemia,causing spinal nerve compression without any other symptoms.Following standard chemotherapy,spinal canal compression can be quickly relieved,and the spinal cord and nerve function restored,avoiding emergency surgery.
