Background: Schwannomas of the cauda equina are rare intradural primary spinal tumors. Many of these patients initially present with cauda equina syndromes, and only 2.2% demonstrate clinical recurrence. Gross total excision is the procedure of choice. Case Description: A 62-year-old female had undergone resection of a cauda equina schwannoma 5 years previously. She newly presented with cauda equina symptoms attributed to a recurrent schwannoma. Following gross total secondary tumor resection, the patient’s preoperative deficits fully resolved, and the tumor never recurred. Conclusion: Secondary gross total excision of schwannomas of the cauda equina is critical to avoid further tumor recurrence.

AbstractBackgroundAn astroblastoma is a rare primary glial tumour occurring preferentially in young adults. It is characterised by a perivascular arrangement of tumour cells forming perivascular pseudorosettes mimicking ependymomas. The histogenesis of astroblastoma is unclear.Case descriptionWe present the history of a 13-year-old girl with chief complaints of headache associated with vomiting, blurring of vision on the left eye and a history of diplopia on the right eye. She underwent left parietal parasagittal craniotomy and near-total excision of tumour. She was planned for postoperative radiotherapy 5,940 cGy in 28 fractions along with concurrent temozolamide100 mg. She had no neurological deficit or complaints during her last visit.ConclusionAstroblastomas are a distinct clinic pathologic entity, with well-described radiologic, pathologic and cytogenetic features. Its recurrence is high, and efforts must be made to elucidate the role and usefulness of radiotherapy and chemotherapy in these tumours.

Lost To Follow Up

Abstract Seven of fourteen children with spinal cord ependymoma had myxopapillary tumors of the filum terminale. These tumors made up 15.9% of all primary spinal neuroectodermal tumors in children (44 cases) seen during a 62-year period (1919 to 1981). Their clinical presentation, radiological features, pathological findings, treatment, and outcome are reported. Six of the seven patients were known to be alive at the time of writing. The seventh patient was lost to follow-up after 3 years without tumor recurrence. Of 5 patients whose primary mode of treatment was operation alone, 3 had intraspinal or intracranial recurrences. Despite tumor recurrences, 2 patients were long term survivors after further operation and irradiation, whereas the third patient recently received craniospinal irradiation for intracranial tumor recurrence. The 2 patients who did not have tumor recurrence after operation alone had been followed for 3 and 7 years, respectively. Two children with subtotal tumor resection and spinal irradiation had no recurrences at 1 and 17 years, respectively. Our data suggest that this unusual subtype of spinal ependymoma is not uncommon during childhood and has a good prognosis. All patients with this tumor require prolonged follow-up for tumor recurrence after operation and irradiation.

Abstract BACKGROUND AND IMPORTANCE: Three-dimensional ultrasound navigation has been performed to assist in resection of cranial and spinal tumors, but to the best of our knowledge, no one has described the use of real-time 3-dimensional ultrasound navigation in the resection of neck tumors beyond biopsy. CLINICAL PRESENTATION: This case report describes the use of 3-dimensional ultrasonic navigation in assisting with resection of a large neck paraganglioma. The 3-dimensional ultrasonic navigation improved real-time visualization of the carotid arteries, the trachea, and other vital structures. CONCLUSION: The use of 3-dimensional ultrasound navigation should be considered in aiding resection of large neck tumors because it can allow more efficient and safer tumor resection.

Previous Diagnosis

Background: Neurofibromatosis 1 (NF1) has a broad spectrum of clinical manifestations, most typically involving café-au-lait spots and skin neurofibromas. Only 2% of patients with NF1 have symptomatic spinal tumors. Case Description: A patient with a previous diagnosis of NF1 presented with cervicalgia, dysphagia/mild dysphonia, gait alteration, and progressive hypoesthesia involving all four limbs. The magnetic resonance documented a giant dumbbell neurofibroma arising between the C2 and C3 levels which extended toward the foramen magnum, causing medullary and bulbar compression. The major challenge of surgical management was the enormous size and location this C2–C3 (5 cm × 4 cm × 5.1 cm) lesion. Conclusions: Compression of the foramen magnum attributed to a dumbbell giant spinal neurofibroma at the C2C3 level resulting in prebulbar cisterns should be among the differential diagnostic considerations for patients presenting with tetraparesis and underlying NF1.

Formidable Challenge

Abstract Extensive multifocal intradural lesions in children present a formidable challenge. This surgical video illustrates our management of a 14-yr=old boy with two intradural mass lesions on magnetic resonance imaging (MRI): one at T2-5 and the other from T12 through the sacral cul-de-sac. In a single procedure, we performed a T2-5 laminectomy and laminoplasty and T12-sacrum laminectomy for tumor resection. For reconstruction, we performed complete laminoplasty at all levels with supplementation at the thoracolumbar junction via T11-L2 posterior spinal fixation and allograft placement for fusion. In this video, we illustrate the microsurgical challenges of intradural tumor resection in both the thoracic cord and amidst the cauda equina. In young patients, prevention of postsurgical spinal deformity is of paramount concern. We discuss considerations for long-segment spinal stabilization in an adolescent and describe our decision-making to perform stabilization at the thoracolumbar junction to supplement laminoplasty while preserving function. The patient and their family consented to the procedure.  Image of the article at 0:51 is from McGirt et al, Short-term progressive spinal deformity following laminoplasty versus laminectomy for resection of intradural spinal tumors: analysis of 239 patients, Neurosurgery, 2010, 66(5), 1005-1012, by permission of the Congress of Neurological Surgeons.

Spine Case

Background: Meningiomas are common intradural extramedullary spinal tumors with a predilection for the thoracic spine. They are mostly benign (90%), with only a few showing malignant potential. However, circumferential intradural meningiomas surrounding the spinal cord are exceptionally rare. Here, we present a 40-year-old patient with a T6-T7 circumferential lesion who underwent surgery. In addition, we reviewed three similar cases previously reported in the literature. Case Description: A 40-year-old female presented with paraparesis. Imaging demonstrated a T6-T7 thoracic circumferential intradural lesion, considered to most likely be a meningioma. At surgery, the posterolateral portion of the tumor was removed, but there was residual ventral disease. The tumor recurred several years later, and was again partially removed, now leaving her with a residual neurological deficit. Three similar cases of circumferential meningiomas, one cervical and two thoracic, were reported from the literature. Conclusion: Circumferential meningiomas pose unique and significant surgical challenges, particularly since resection of the posterolateral components is feasible, but some tumor may have to be left ventrally to avoid injury to the anterior spinal artery, that may recur.

Background: Pancreatic ductal adenocarcinoma (PDAC) is the most common pancreatic malignancy, which rarely metastasizes to the spine. Case Description: Here, we present a lytic lumbar metastatic PDAC resulting in severe epidural spinal cord compression (ESCC) with instability. The lesion required preoperative particle embolization, surgical decompression, and fusion. Conclusion: This case report shows that PDAC may metastasize to the lumbar spine requiring routine decompression with fusion.

A number of milestones have marked the development of transsphenoidal pituitary tumor resection this century. The introduction of headlamp illumination, followed by the use of the operating microscope and fluoroscopy have allowed neurosurgeons to perform this surgery in a safe and highly effective manner. With the aid of a case report, we describe the incorporation of endoscopic techniques in pituitary tumor resection. The technique described is minimally invasive, avoiding septal dissection and allowing unsurpassed, unobstructed, and panoramic visualization of the region of interest to the surgeon and operative team.
