Article Synopsis
  • The study examined the link between bladder dysfunction after surgery and various preoperative and surgical factors in patients with spinal myxopapillary ependymoma (MPE).
  • It included 8 patients aged 21 to 76, who underwent tumor removal from 2011 to 2021, and categorized bladder dysfunction as mild or severe post-surgery.
  • Findings suggested that performing gross total resection (GTR) in cases with intraoperative adhesions could worsen bladder function, highlighting the importance of careful surgical techniques to minimize risks.

Article Synopsis
  • - A 48-year-old woman experienced severe lower back pain radiating to her right leg, diagnosed with an intradural neuroenteric cyst at the L2 level via MRI.
  • - The cyst was T2 hyperintense and T1 isointense, and histological analysis confirmed it was a well-defined ovoid neuroenteric cyst, appearing brighter than cerebrospinal fluid.
  • - Following cyst removal and L2 laminectomy, the patient experienced significant pain relief and had completely recovered by a two-week follow-up, highlighting the effectiveness of MRI and surgical intervention.

Article Synopsis
  • Surgical resection is the main treatment for conus medullaris and cauda equina tumors, but achieving complete removal can be difficult and risky, making intraoperative neurophysiological monitoring (IONM) crucial for safer procedures.
  • This study focuses on the effectiveness of monitoring the bulbocavernosus reflex (BCR) during surgeries to improve outcomes for patients undergoing CMCET resection.
  • The results showed that specific measures of BCR waveform reductions were strongly linked to postoperative voiding dysfunction, providing a potential method to predict these complications.

Background: Ependymomas, rare glial brain tumors, account for <5% of all brain tumors. Interestingly, over 60% of ependymomas occur in the spinal cord of adults, including those originating from the filum terminale, while the rest are found within the brain. The World Health Organization (WHO) categorizes ependymomas into three grades: subependymomas and myxopapillary ependymomas ([MEPNs]; WHO grade I), classic ependymomas (WHO grade II), and anaplastic ependymomas (WHO grade III).

Background: Patients affected by Von Hippel-Lindau (VHL) are prone to develop central nervous system neoplasms such as hemangioblastomas (HBs). Myxopapillary ependymoma (MPE) is not commonly associated with VHL disease.

Case Description: We present the first case of a VHL patient affected by simultaneous silent cauda equina MPE and a symptomatic conus medullaris HB.

Article Synopsis
  • A case study details a 44-year-old male with persistent lower back pain, where MRI identified a large tumor at L1-S4, leading to a biopsy that confirmed myxopapillary ependymoma, followed by partial tumor resection and radiation therapy due to observed metastases.
  • Despite surgery, there remains a chance of tumor recurrence, highlighting the importance of preoperative imaging to check for metastases and the need for adjuvant treatments like radiation to reduce this risk.

Article Synopsis
  • * The aims of the surgery were to relieve the pressure caused by the tumor, obtain a diagnosis, prevent further neurological issues, and achieve a potential cure.
  • * The pathology confirmed the tumor as a myxopapillary ependymoma, a rare type of tumor that typically occurs in specific spinal areas, and the video discusses the surgical process, clinical outcomes, and treatment options related to this condition.

Article Synopsis
  • * An 11-year-old girl experienced worsening back pain radiating to her legs for five years, and after imaging revealed an intramedullary cyst, she underwent surgery that successfully removed the cyst and improved her symptoms.
  • * Neurosurgeons recognize these rare intramedullary epidermoid cysts, with MRI being the preferred diagnostic tool, and recommend surgical removal in symptomatic cases, along with careful techniques to minimize complications and the chance of recurrence.

Myxopapillary ependymoma (MPE) is an uncommon variant of ependymoma, almost exclusively seen in conus medullaris or filum terminale. MPE can be diagnostically challenging, especially when arising extra-axially. Here we report 5 cases of superficial soft tissue/cutaneous MPE, identified across three tertiary institutions.

Background: Myxopapillary ependymoma is a rare type of primary spinal tumor, it is distinctly a slow-growing tumor that originates in the conus medullaris, cauda equina, or film terminals and is rarely identified as a multicentric type. Myxopapillary ependymoma has a unique histological characteristic and is associated with a generally better prognosis.

Objective: We present a case of a rare multicentric myxopapillary ependymoma.

Objective: Untethering surgery for a tight filum terminale is a common treatment with considerable efficacy and safety. On the other hand, retethering has been reported to occur. One of the major mechanisms of retethering is adherence of the cut end of the sectioned filum to the midline dorsal dural surface.

Myxopapillary ependymoma (MPE) is a primary tumor of the central nervous system (CNS), characteristically an indolent malignancy involving the spinal conus medullaris, Filum terminale or cauda equina. We present a rare case of MPE, recurrent in the pelvic soft tissue with eventual pleural and intra-pulmonary metastasis. Refractory to repeated gross resection, adjuvant radiotherapy, platinum-based chemotherapy and temozolomide exploitation of mutant somatic BRCA1 status with the addition of a poly (ADP-ribose); polymerase inhibitor (PARPi) in a novel combination regimen with olaparib-temozolomide (OT) has achieved stable radiological disease after 10 cycles.

Division of Pediatric Neurosurgery, Hokkaido Medical Center for Child Health and Rehabilitation.

Filum lipomas, a subtype of spinal lipomas, are ectopic fat tissue deposits of the filum terminale categorized as closed spinal dysraphism. They are occasionally and incidentally observed on MRI images, but generally require little surgical treatment. Early untethering surgery is recommended for symptomatic patients, whereas asymptomatic patients presenting normal level of the conus medullaris require no therapy and are regarded as having a normal variation.
