  • Title: Adult pilocytic astrocytoma of conus medullaris: clinical considerations and review of the literature.
    Author: Lavrador JP, Oliveira E, Pimentel J, Livraghi S.
    Journal: CNS Oncol; 2017 Apr; 6(2):107-110. PubMed ID: 28425761.
    Abstract:
    Astrocytomas are responsible for 30% of all primitive intramedullary tumors with cervicothoracic predominance. However, only about one hundred cases of intramedullary pilocytic astrocytomas were described. The authors described the case of a 69 year-old patient presenting with a broad-base gait, bilateral pain and dysesthesia of inferior limbs with a diagnosis of an intra-axial cystic lesion centered to the conus medullaris, diagnosed as pilocytic astrocytoma of conus medullaris (PACM) after surgery. To the best of our knowledge, only two previous reports concerning PACM were made. As benign lesions associated with long survivals, function should be the mainstay of treatment of PACM. Surgical resection should be performed. Adjuvant radiotherapy or chemotherapy has no establish role in pilocytic astrocytic lesions.
