Grade II pilocytic astrocytoma in a 3-month-old patient with encephalocraniocutaneous lipomatosis (ECCL): case report and literature review of low grade gliomas in ECCL.

Encephalocraniocutaneous lipomatosis (ECCL) is a rare congenital syndrome with an unknown etiology. Since 1970, around 60 cases have been reported in English literature. ECCL is usually classified by cutaneous lesions and non-progressive intracranial or spinal lipomas; however three cases of ECCL associated with low grade glioma (LGG) have been described. We report on the fourth case of LGG in a patient with ECCL; a grade II pilocytic astrocytoma with pilomyxoid features in a 3-month-old male, the youngest in literature.
