1989～1990年我院收治的鼻咽癌(NPC)病例中,有45例同时作常规X线照片和CT扫描。本文探讨CT扫描对NPC颅底骨质破坏的诊断价值,以及临床症状与颅底破坏之间的关系。 资料与方法:45例NPC病人中,初发33例,复发12例。初发NPC按临床分型,以颅神经症状为主的为上行型,以颈部淋巴结肿大为主的为下行型,同时兼有颅神经症状和颈部淋巴结肿大或者仅有鼻咽部肿瘤的为混合型。常规X线照片包括鼻咽侧位和颅底位,CT扫描一般只作平扫,少数加冠状扫描,根据上述一种或二种检查方浃确定有无颅底骨质破坏。
Of the cases of nasopharyngeal carcinoma (NPC) admitted to our hospital from 1989 to 1990, 45 cases underwent conventional X-ray and CT scans. This article discusses the diagnostic value of CT scans for the destruction of skull base in NPCs, and the relationship between clinical symptoms and skull base destruction. Materials and Methods: Of the 45 patients with NPC, 33 were newly diagnosed and 12 were relapsed. Initial NPC was classified according to clinical types, with cranial nerve symptoms as the ascending type, and cervical lymphadenopathy as the descending type. It also had cranial nerve symptoms and neck lymph nodes or only nasopharynx. The tumor is mixed. Conventional radiographs include the nasopharyngeal lateral and cranial basements. CT scans are generally performed only on plain scans, and a few are coronal scans. Skull base bone destruction is determined based on one or two of the above-mentioned examinations.
