We report a new case of encephalocraniocutaneous lipomatosis, a rare neurocutaneous syndrome of unknown etiology with involvement of tissues arising from the mesoderm and ectoderm: skin, eye, adipose tissue, and brain. We also review the neurologic manifestations of the syndrome, the most frequent of which include seizures, ventricular enlargement, calcifications, mental retardation, and cerebellopontine angle tumor. Our patient had an extensive extradural spinal cord lipomatous lesion, emphasizing the importance of screening for spinal abnormalities in asymptomatic patients with this condition.
