Primitive neuroectodermal tumors are rare among domestic veterinary species, but young dogs and cattle appear to be the most frequently affected.

When age is not a consideration, the most common primary intracalvarial, intra-axial tumors of dogs are astrocytomas, oligodendrogliomas, choroid plexus tumors, and lymphosarcomas. However, the incidence of all these tumors changes with age and in a dog weeks of age (as was the dog of the present report), a PNET becomes a more likely differential diagnosis for primary intracranial neoplasia. Primitive neuroectodermal tumors can be most broadly defined as a heterogeneous group of tumors of embryonal neuroectodermal origin…
