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 the meninges in a Nilgai antelope (Boselaphus tragocamelus). Histologically, the tumour had a conspicuous microcystic appearance with features similar to the histological subtype of microcystic meningioma described in humans. This is the first such tumour reported in this species.

Nilgai羚羊（Boselaphus tragocamelus）的微囊性脑肿瘤：推定的微囊性脑膜瘤

神经系统肿瘤在野生和圈养哺乳动物中很少见。在本报告中，我们描述了一种起源于Nilgai羚羊 ( Boselaphus tragocamelus )脑膜的颅内、实性、占位性病变。在组织学上，肿瘤具有明显的微囊性外观，其特征类似于人类描述的微囊性脑膜瘤的组织学亚型。这是该物种中报告的第一个此类肿瘤。
