A 49-year-old woman had a palpable mass in her occipital region. Plain radiographs and CT examination revealed extensive atlantooccipital pneumatization with findings consistent with the diagnosis of mastoid pneumocele. Decompression was achieved with placement of a myringotomy tube, resulting in prompt symptomatic relief. On a follow-up CT examination, the pneumatized areas had become opacified and new bone formation was present.
一名49岁女性枕部可触及肿块。X线平片和CT检查显示寰枕广泛气化,结果符合乳突气囊肿的诊断。通过放置鼓膜切开置管实现减压,症状迅速缓解。在后续CT检查中,气化区域已变得模糊,出现了新骨形成。
