Medulloepithelioma

Medulloepitheliomas are rare, highly malignant, primitive embryonic tumor derived from the primitive medullary plate and neural tube. It is essentially a tumor of childhood with the age of onset between 6 months and 5 years.

Pathology

Medulloepitheliomas are classified as embryonal tumours in the WHO classification of CNS tumours 3

Radiographic features

On non-contrast CT scan the lesion is either isodense or hypodense with variable heterogeneity and calcification. The tumor enhances with contrast.

Treatment and prognosis

Medullary epithelioma carries dismal prognosis with a median survival of 5 months. On the other hand, medulloepitheliomas occurring in the eye or the orbit generally benefit from a gross-total resection and may present a good prognosis.
