Bilateral superior oblique palsy is an uncommon ocular motility problem, the commonest cause being closed head trauma. Two cases, both adults, are presented in whom bilateral superior oblique palsy occurred as a result of neoplastic infiltration of the dorsal midbrain in the region of the anterior medullary velum. In the absence of a history of head trauma, the presence of an acquired bilateral superior oblique palsy is a definite sign of a single lesion in the region of the decussation of the trochlear nerves and appropriate imaging is indicated.
双侧上斜肌麻痹是一种罕见的眼球运动障碍，最常见的病因是闭合性头部外伤。本文报告两例成人病例，双侧上斜肌麻痹是由前髓帆区域中脑背侧的肿瘤浸润所致。在没有头部外伤史的情况下，后天性双侧上斜肌麻痹的出现是滑车神经交叉区域单一病变的明确征象，需要进行适当的影像学检查。
