Peripheral nerve tumours, called schwannomas, because they are derived from cells of the Schwann sheath, are rare tumours that can involve any part of the body, but are essentially located on the limbs, which represent more than 50% of cases. Schwannomas of the trunk and especially pelvic schwannomas are even rarer. A tumour arising from the obturator nerve is exceptional, but its paravesical location can facilitate the diagnosis, as in this case. The complementary investigations most frequently performed are CT and MRI, although they are unable to define the exact nature of the tumour. Surgery must try to preserve continuity of the nerve, but that is not always possible and does not appear to have any major consequences in this site.
周围神经肿瘤，称为神经鞘瘤，因为它们起源于施万鞘细胞，是一种罕见的肿瘤，可累及身体的任何部位，但主要位于四肢，超过50%的病例发生在此处。躯干神经鞘瘤，尤其是盆腔神经鞘瘤更为罕见。起源于闭孔神经的肿瘤非常罕见，但其膀胱旁位置有助于诊断，本病例即是如此。最常进行的辅助检查是CT和MRI，尽管它们无法明确肿瘤的确切性质。手术必须尽量保留神经的连续性，但这并非总是可行，而且在这个部位似乎没有任何重大后果。
