A rare cause of backache: epidural lymphangioma of the cervicothoracic spine

Spinal lymphangiomas: Case-based review of a chameleonic disease entity

Purpose

Lymphangiomas are benign hamartomas in the spectrum of lymphatic malformations, exhibiting multifaceted clinical features. Spinal involvement is exceedingly rare, with only 35 cases reported to date. Both due to their rarity and chameleonic radiologic features, spinal lymphangiomas (SLs) are usually misdiagnosed; postoperatively, surgeons are thus confronted with an unexpected histopathological diagnosis with sparse pertinent literature and no treatment guidelines available.

Methods

Here, we report the case of a 67-year-old female who underwent surgery for a T6-T7 epidural SL with transforaminal extension, manifesting with spastic paraparesis. Then, we present the results of the first systematic review of the literature on this subject, delineating the clinical and imaging features and the therapeutic implications of this rare disease entity.

Results

Our patient was treated with T6-T7 hemilaminectomy and resection of the epidural mass, with complete recovery of her neurological picture. No recurrence was evident at 18 months. In the literature, 35 cases of SL were reported that can be classified as vertebral SL (n = 18), epidural SL (n = 10), intradural SL (n = 3), or intrathoracic lymphangiomas with secondary spinal involvement (n = 4). Specific treatment strategies (both surgical and nonsurgical) were adopted in relation to each of these categories.

Conclusion

Gathering knowledge about SL is fundamental to promote both correct preoperative identification and appropriate perioperative management of this rare disease entity. By reviewing the literature and discussing an exemplary case, we delineate a framework that can guide surgeons facing such an unfamiliar diagnosis.

Acute spontaneous thoracic epidural hematoma associated with intraspinal lymphangioma: A case report

BACKGROUND

Spontaneous spinal epidural hematoma is a rare neurosurgical emergency.

CASE SUMMARY

A 53-year-old healthy woman suffered from complete paraplegia in both legs and loss of all sensation below the xiphoid process. She was diagnosed as acute spontaneous thoracic epidural hematoma caused by an intraspinal lymphangioma. The primary lab survey showed all within normal limits. Presence of a posteriorly epidural space-occupying lesion at the T4-T8 level of the spinal canal was confirmed on magnetic resonance imaging. A decompressive laminectomy was performed from the T4 to T7 levels at the sixth hour following abrupt onset of complete paraplegia. The lesion was confirmed as lymphangioma. This patient recovered well within one month.

CONCLUSION

This study reports a case of acute spontaneous thoracic epidural hematoma caused by an intraspinal lymphangioma with well recovery after surgical intervention.

Lymphangioma of the Thoracic Spine with Epidural Compression: A Case Report

Lymphangiomas are benign lesions consisting of abnormal proliferations of lymphatic vessels. Lymphangiomas associated with bone involvement, particularly in vertebral bodies, accompanied by cord compression, are extremely rare, and our literature review yielded only a few relevant reports. We describe a 61-year-old man presenting with progressive paraparesis and sphincter disturbance of 5 months' duration. Magnetic resonance imaging (MRI) revealed an enhancing T8 vertebral body involvement as well as a homogeneously enhancing posterior epidural mass at the T7-T8 level, with severe cord compression and cerebrospinal fluid (CSF) blockade. The patient underwent surgery via T7-T8 laminectomy, and after the removal of the epidural mass, the surgical procedure was stopped due to severe bleeding. Histopathologic examination reported a lymphangioma. After 10 days, the patient was able to walk. In the sixth postoperative month, MRI showed complete relief of the mass effect. The wide spectrum of the preoperative differential diagnosis of lymphangiomas renders a definite preoperative diagnosis impossible; therefore, histopathologic examination is the sole definite route for their diagnosis. In case of the solitary lymphangiomas of the spine with epidural compression, preoperative angiography and embolization should be considered to reduce intraoperative bleeding and enhance the chance of total resection and total surgical resection should be performed to decrease the likelihood of recurrence.
