Primary intramedullary spinal cord tumour in pregnancy: a case report

Point-of-care ultrasound (POCUS) in the surgery of a paraplegic pregnant female: A case of "do no harm"

We present here a case of multidisciplinary management of a 20-year-old pregnant woman who presented with sudden paraplegia attributed to a large paraspinal tumor. Magnetic resonance imaging (MRI) revealed compressive dorsal myelopathy due to an extramedullary tumor. Given the urgency of her symptoms and pregnancy status, a multidisciplinary team decided to proceed with surgery while avoiding radiation exposure (eg, O/C-arm). Intraoperative point-of-care ultrasound (POCUS) was utilized for tumor localization and surgical guidance, facilitating successful gross total excision with minimal risk to the fetus. Postoperative recovery was uneventful, with improvement in muscle strength and preservation of the pregnancy. Beyond tumor localization, POCUS offers additional benefits in assessing maternal hemodynamics and detecting potential complications. This case highlights the utility of POCUS as a radiation-free theranostic imaging modality in pregnant patients with spinal tumors, enhancing safety in surgery and optimizing outcomes for both mother and fetus.

Fatal holocord recurrence of a pregnancy-related, low-grade spinal ependymoma: case report and review of an unusual clinical phenomenon

INTRODUCTION

Pregnancy-related spinal tumors (PRSTs) are unusual tumors that present during pregnancy or within a year after delivery. We describe a fatal holocord recurrence of a spinal ependymoma, which, to the best of our knowledge, is one of the most extensive PRSTs reported thus far.

CASE PRESENTATION

A 21-year-old primigravida presented at 6 months of gestation with urinary incontinence for 2 months and spastic paraparesis for 1 month. MRI showed a conus intramedullary lesion from T10 to 12. Near-total resection of the lesion was performed. The histopathological diagnosis was that of a cellular ependymoma (WHO grade II). The patient presented 6 months later with progressive quadriparesis and breathing difficulty. MRI demonstrated holocord recurrence of the tumor with edema extending to the pontomedullary junction. The patient succumbed to respiratory failure before decompression of the tumor could be performed.

DISCUSSION

This case highlights an unusual clinical course of a pregnancy-related, low-grade spinal ependymoma. The possible hormonal and genetic mechanisms underlying the aggressive involvement of the entire spinal cord by the recurrent tumor are discussed in the light of a literature review. Future studies may shed light on the possibility of utilizing these mechanisms as therapeutic targets to alter the clinical course of aggressive spinal ependymomas.

Diagnosis and rehabilitation of a pregnant woman with spinal cord disorder due to spinal cord tumor

Introduction

Spinal cord tumors are a rare cause of spinal cord disorder (SCD). Early diagnosis can be challenging, especially in patient populations with other potential etiologies for back pain, such as pregnant women.

Case presentation

A 28-year-old female presented at 8 weeks gestation with thoracic back pain initially diagnosed as gestational low back pain. Her symptoms progressed to lower extremity weakness. After diagnosis and resection of a spinal cord ependymoma, we collaborated with the inpatient interdisciplinary team to devise a rehabilitation program focused on minimizing pregnancy-related complications and optimizing care of a newborn in the setting of a new paraplegia.

Discussion

Providers should not assume all pregnant women with low back pain have gestational back pain, as it can be due to more insidious causes. The rehabilitation course for women who develop an SCD during gestation should be carefully tailored toward their pre- and post-natal care and with the education of how the disorder can affect pregnancy and parenting.
