The authors report an underestimated symptom and sign arising in pineal region tumours: tinnitus and hearing loss. It has been observed in 13 out of 72 pineal region tumours (18%). Three illustrative cases are reported in this paper. The inferior colliculi, the structure more dense in fibres than any other auditory brain stem site and at which majority of the acoustic pathways relay, is closely adjacent to the pineal body. Displacement of this structure may be responsible for acoustic symptoms together with common visual symptoms.
耳鸣和听力损失。在72例松果体区肿瘤中有13例（18%）观察到这种情况。本文报告了3个说明性病例。下丘是纤维比任何其他听觉脑干部位都更密集且大多数听觉通路在此中继的结构，它与松果体紧密相邻。该结构的移位可能与常见的视觉症状一起导致听觉症状。
