Microcystic Cerebral Neoplasm in a Nilgai Antelope (Boselaphus tragocamelus): Putative Microcystic Meningioma

Tumours of the nervous system are rare in wild and captive mammals. In this report, we describe an intracranial, solid, space-occupying lesion originating from meninges a Nilgai antelope (Boselaphus tragocamelus). Histologically, tumour had conspicuous microcystic appearance with features similar to histological subtype meningioma described humans. This is first such reported species.
