Occipital condyle fractures are rare. When present, they produce lower cranial palsies and/or brainstem dysfunction. A 32 year old man sustained multiple injuries. At the time of admission the patient had no neurological deficits. Three weeks after the accident, the patient complained of slurring of speech. Clinical examination revealed an isolated hypoglossal palsy. Radiological evaluation revealed an occipital condyle fracture. The patient was treated with a rigid collar. Eighteen months after the injury, the patient noted slight improvement in his speech. However, clinical examination showed a persistent hypoglosssal palsy. Occipital condyle fractures are rare. They may be associated with lower cranial nerve palsies. As demonstrated by this case, this entity should be included in the differential diagnosis of hypoglossal palsy. Since occipital condyle fractures can exist without neurological deficits, special attention should be paid to imaging of the craniovertebral junction in patients with head injury.
枕髁骨折很少见。一旦出现,会导致低位颅神经麻痹和/或脑干功能障碍。一名32岁男性遭受多处损伤。入院时患者没有神经功能缺损。事故发生三周后,患者主诉言语含糊不清。临床检查发现单纯舌下神经麻痹。影像学评估显示枕髁骨折。患者接受了硬颈托治疗。受伤18个月后,患者注意到其言语有轻微改善。然而,临床检查显示舌下神经麻痹持续存在。枕髁骨折很少见。它们可能与低位颅神经麻痹有关。如本病例所示,该病症应列入舌下神经麻痹的鉴别诊断中。由于枕髁骨折可能在没有神经功能缺损的情况下存在,因此对于头部受伤的患者,应特别注意颅颈交界区的影像学检查。
