  • Title: Holocord Pilocytic Astrocytoma in an Adult: A Rare Case Report and Review of the Literature.
    Author: Baran O, Kasimcan O, Sav A, Oruckaptan H.
    Journal: World Neurosurg; 2019 Jun; 126():369-375. PubMed ID: 30902768.
    Abstract:
    BACKGROUND: Intramedullary 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 DESCRIPTION: A 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. CONCLUSIONS: Reported 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.
