Subependymal glioneuronal hamartoma in the mesencephalic aqueduct of a giraffe.
A 1-day-old male giraffe calf (Giraffa camelopardalis) was submitted for necropsy examination after sustaining postnatal head trauma from the cow. In addition to the expected findings of severe cerebral edema and epidural and subarachnoid hemorrhage, there also was present an incidental finding of a subependymal glioneuronal aqueductal hamartoma. Reports of this type of congenital lesion are rare in the human literature, and the lesion has not, to the authors' knowledge, previously been reported in this or any other veterinary species.
