目的探讨鼻腔恶性肿瘤的CT诊断价值,以提高其诊断准确性。方法回顾性分析52例经手术或活检证实的鼻腔恶性肿瘤患者的CT表现。结果肿瘤原发于鼻腔者45例,鼻腔、鼻窦同时发病或者累及临近结构者7例。CT表现:恶性肿瘤位于鼻腔前部48例,后部4例,肿瘤浸润鼻前庭、鼻翼及邻近面部皮肤23例,侵犯上颌窦、筛窦、鼻咽部等临近结构16例,临近骨破坏7例,病灶密度均匀19例,不均匀27例,增强后轻度强化9例,中度强化11例。结论CT扫描能够明确鼻腔恶性肿瘤部位、大小及骨组织破坏,为临床诊治鼻腔恶性肿瘤提供医学影像学资料。
Objective To investigate the value of CT in the diagnosis of nasal cavity malignancy to improve its diagnostic accuracy. Methods The CT findings of 52 patients with nasal malignancy confirmed by surgery or biopsy were retrospectively analyzed. Results 45 cases of primary tumors in the nasal cavity, nasal sinus and nasal sinus at the same time, or involving the adjacent structure in 7 cases. CT manifestations: Malignant tumors were located in the anterior nasal cavity in 48 cases and in the posterior portion in 4 cases. The tumor infiltrated the nasal vestibule, the nose and adjacent facial skin in 23 cases, which infringed 16 adjacent structures such as the maxillary sinus, ethmoid sinus and nasopharynx, For example, there were 19 cases of uniform density of lesions, 27 cases of non-uniform density, 9 cases of mild enhancement after enhancement and 11 cases of moderate enhancement. Conclusions CT scan can clarify the location, size and destruction of bone tissue of nasal cavity, and provide medical imaging information for clinical diagnosis and treatment of nasal cavity malignancy.
