BackgroundIntramedullary glial neoplasms affecting the entire spinal cord from the cervicomedullary junction to conus medullaris are termed holocord tumors. Pilocytic astrocytomas are relatively uncommon tumors forming holocord involvement. Hitherto 24 holocord astrocytoma cases were reported in the literature. Here, a case of an adult holocord pilocytic astrocytoma was presented.Case DescriptionA 29-year-old female patient presented with a subtotal resection. Histopathologic examination revealed pilocytic astrocytoma, World Health Organization grade 1, presenting holocord involvement. Magnetic resonance imaging showed a mass containing necrotic and cystic foci leading to an expansion along the entire spinal cord extending from C4 to conus medullaris.ConclusionsReported holocord pilocytic astrocytomas in the relevant literature cases were reviewed. When evaluating magnetic resonance imaging scans of adult patients with various neurologic symptoms, i.e., weakness and fecal and urinary incontinence, pilocytic astrocytoma should be considered among differential diagnoses of intramedullary mass lesions.Copyright © 2019 Elsevier Inc.
