Here we report a case in which a 42-year-old male presented with subjective tinnitus of three months, with no pulmonary disease symptoms. Pure tone audiometry indi-cated moderate conductive deafness in left ear with an air-bone gap of 21.3 dB. HRCT temporal bone scan-ning indicated high-density shadows in the left epitympanic cavity, sinus tympani and mastoid cavity. Chron-ic otitis media with cholesteatoma was suspected and surgical treatment recommended. However, preopera-tive chest x-ray revealed high-density millet lesions scattered widely in both lungs. HRCT lung scanning confirmed the lungs lesions and indicated lung cancer. In order to determine correlations between the tempo-ral bone and pulmonary lesions, a CT-guided trans-mastoid aspiration biopsy and immunohistochemical study were conducted, which confirmed that the temporal bone lesion was metastatic from the lungs. The pa-tient was given a series of chemotherapy immediately and his tinnitus significantly improved after three months of treatment, with full recovery of his hearing and complete resolution of shadows in the mastoid cavity. Unfortunately, he subsequently developed multiple bone metastases in the 9th month and cerebral metastasis in the 18th month. Multiple organ failure resulted in death in 2.5 years.展开更多
文摘目的 探讨CT引导下经皮肺穿刺活检并发症的影响因素及处理方法。方法 回顾性分析253例CT引导下经皮肺穿刺活检并发症的影响因素及相应处理方法。结果 253例中,77例(77/253,30.43%)肺出血,包括4例(4/77,5.19%)大量出血,有无肺出血患者的病变位置、病灶大小、穿刺深度、取材数量差异均有统计学意义( P 均<0.05);55例(55/253,21.74%)发生气胸,其中5例接受胸腔闭式引流,有无气胸患者的病变位置、病灶大小、取材数量差异均有统计学意义( P 均<0.05)。结论 CT引导下经皮肺穿刺活检后肺出血的影响因素为病变位置、病灶大小、穿刺深度及取材数量,气胸的影响因素为病变位置、大小及取材数量,均可预防、可处理。
