Intramedullary spinal cord lesions in children.

J Pak Med Assoc 2021 Feb;71(2(B)):775-777

Section of Neurosurgery, Department of Surgery, Aga Khan University Hospital, Karachi.

Paediatric intramedullary spinal cord lesions are uncommon pathologies, prone to result in dismal prognosis if not managed promptly and aggressively. While children usually present in good functional grades compared to adults, early recognition and treatment is important to improve outcomes. In this review, we present tumour demographics, patient factors, and treatment modalities of intramedullary spinal cord lesions in paediatric patients. Read More

Refining the treatment of spinal cord lesions: experience from 500 cases.

Neurosurg Focus 2021 May;50(5):E22

Objective: Tumorous lesions of the spinal cord, as well as some vascular lesions like cavernous hemangiomas, demand careful consideration as to the indication and approach for surgery. As these lesions are rare in any departmental series, refinement of treatment strategies evolves over long periods. In this context, the authors evaluated a series of 500 intramedullary lesions for approach, technique, outcome, complications, and follow-up. Read More

Concomitant KIAA1549-BRAF fusion and IDH mutation in Pediatric spinal cord astrocytoma: a case report and literature review.

Brain Tumor Pathol 2021 Apr 28;38(2):132-137. Epub 2021 Feb 28.

Department of Pathology, Xuanwu Hospital, Capital Medical University, Beijing, China.

Primary tumors of the spinal cord are rare, accounting for 3-6% of tumors in the central nervous system, particularly in children. KIAA1549-BRAF fusion is more common in pilocytic astrocytoma (PA) and IDH1 R132H mutation is rare in infratentorial tumors. Here, we report a 10-year-old male patient who presented with weakness in lower limbs that progressed to difficulty walking. Read More

[Spinal tumors].

Radiologe 2021 Mar 11;61(3):267-274. Epub 2021 Feb 11.

Klinik für Diagnostische und Interventionelle Neuroradiologie, Klinikum Bremen-Mitte/Bremen-Ost, 28205, Bremen, Deutschland.

Spinal tumors are often classified into three anatomical compartments on the basis of their relationship to the dural space and myelon. The most common primary spinal neoplasms are glial tumors (ependymoma, astrocytoma), nerve sheath tumors (schwannoma, neurofibroma) and meningioma. Metastases represent another common tumor entity and can occur in every spinal compartment. Read More

Long-Term Outcomes of Intra-Arterial Chemotherapy for Progressive or Unresectable Pilocytic Astrocytomas: Case Studies.

Neurosurgery 2021 03;88(4):E336-E342

Department of Neurology, Oregon Health & Science University, Portland, Oregon.

Background: Progressive and/or unresectable pilocytic astrocytomas (PAs) carry a poor prognosis compared to typical PA. Early radiotherapy (RT) may have severe long-term neurocognitive side effects in this patient population. Intra-arterial (IA) chemotherapy is a viable alternative or addition to intravenous (IV) chemotherapy, which may be beneficial in avoidance of early RT. Read More

Intramedullary clear cell ependymoma of the lower thoracic spinal cord: report of a new case.

Surg Neurol Int 2020 11;11:423. Epub 2020 Dec 11.

Faculty of Medicine, Universidad Autonoma de Sinaloa, Culiacan, Sinaloa, Mexico.

Background: Clear cell ependymomas (CCEs) are a rare variant of tumors of the nervous system, the main location is the intracranial compartment. Special differential diagnosis should be done with oligodendrogliomas, neurocytoma, glioneurocytoma, astrocytoma, or metastatic renal cell carcinoma, lesions that somehow share cells with clear cytoplasm. Most of these lesions are benign but differential diagnosis is essential to decide further treatment. Read More

MRI characteristics and resectability in spinal cord glioma.

Clin Neurol Neurosurg 2021 01 19;200:106321. Epub 2020 Oct 19.

Department of Neurosurgery, University of Iowa Carver College of Medicine, Iowa City, IA USA. Electronic address:

Objective: The histopathology of intramedullary spinal cord tumors (IMSCT) can be suspected from the MRI features and characteristics. Ultimately, the confirmation of diagnosis requires surgery. This retrospective study addresses MRI features including homogeneity of enhancement, margination, and associated syrinx in intramedullary astrocytomas (IMA) and ependymomas (IME) that assist in diagnosis and predict resectability of these tumors.

Authors:
Dharmender Malik

Clin Nucl Med 2021 Feb;46(2):138-139

From the Department of Nuclear Medicine and PET/CT, Paras Hospitals, Gurugram, Haryana.

Abstract: Glioblastoma multiforme is one of the most common malignant types of tumor arising from the central nervous system known for its devastating intracranial progress and dismal prognosis. Macroscopically evident and symptomatic spinal cord metastasis detected with FDG PET/CT imaging is a rare event. We present a rare case of symptomatic diffuse spinal metastases of glioblastoma multiforme in a 25-year-old woman, who has been previously treated surgically with gross tumor resection followed by adjuvant radiotherapy and chemotherapy with temozolomide.

MR imaging findings in primary spinal cord glioblastoma.

Radiol Case Rep 2021 Jan 2;16(1):72-77. Epub 2020 Nov 2.

Section of Neuroradiology, Department of Radiology, Vall d'Hebron University Hospital, Hospital Vall d'Hebron, Passeig de la Vall d'Hebron, 119-129 | 08035, Barcelona, Spain.

Spinal cord glioblastoma is a rare disease, with an aggressive course and a poor prognosis. We describe magnetic resonance imaging (MRI) findings, in 3 adult cases of biopsy-confirmed glioblastoma. Conventional MRI findings were unclear with regard to the differential diagnosis between this rare tumor and other more common spinal cord lesions, including less aggressive tumors such as ependymoma or pilocytic astrocytoma, abscesses or tumefactive demyelinating lesions.

Introduction: Intramedullary spinal cord gangliogliomas (ISCGGs) account for 35-40% of all intramedullary tumors in children. These tumors have a different algorithm for treatment and prognosis than other medullary tumors, such as astrocytomas and spinal ependymomas. The objective of the study was to review the literature and examine an approach to diagnosing and treating this tumor based on a case report of ISCGG diagnosed at our center. Read More

Discovery of a dual inhibitor of NQO1 and GSTP1 for treating glioblastoma.

J Hematol Oncol 2020 10 21;13(1):141. Epub 2020 Oct 21.

Department of Pathology and Laboratory Medicine, Emory University School of Medicine, Atlanta, GA, USA.

Background: Glioblastoma (GBM) is a universally lethal tumor with frequently overexpressed or mutated epidermal growth factor receptor (EGFR). NADPH quinone oxidoreductase 1 (NQO1) and glutathione-S-transferase Pi 1 (GSTP1) are commonly upregulated in GBM. NQO1 and GSTP1 decrease the formation of reactive oxygen species (ROS), which mediates the oxidative stress and promotes GBM cell proliferation. Read More

University of Iowa Hospital and Clinics, Department of Radiology, Iowa city, IOWA, USA.

Spinal cord lesions are traditionally classified as either extradural or intradural extramedullary or of intramedullary origin. Intramedullary spinal cord tumours are histopathologically similar to cranial tumours with a diverse range of pathologies. Astrocytomas and ependymomas account for approximately 80% of all intramedullary tumours, with other primary and secondary lesions accounting for the remaining 20%. Read More

From the Department of Radiology, Uniformed Services University of the Health Sciences, 4301 Jones Bridge Rd, Bethesda, MD 20814 (R.Y.S.); and Department of Radiology, Mayo Clinic, Rochester, Minn (K.K.K.).

Spinal cord tumors are a challenge for patients and neurosurgeons because of the high risk of neurologic deficits from the disease process and surgical interventions. Spinal cord tumors are uncommon, and approximately 2%-3% of primary intra-axial tumors of the central nervous system occur in the spinal cord. Primary intra-axial tumors are usually derived from neuroepithelial tissue, especially glial cells. Read More
