The radiographic appearance of gastrointestinal Kaposi's sarcoma in patients with AIDS has been described previously, but little attention has been paid to pharyngeal involvement. This study compared the radiographic findings of pharyngeal Kaposi's sarcoma in eight patients with AIDS and dysphagia to those of visual inspection by laryngoscopy or bronchoscopy. Barium pharyngography (six patients) demonstrated nodular lesions without ulceration, ranging in extent from a single nodule to extensive confluent disease. CT (two patients) showed nodular or polypoid intraluminal protrusions, distortion of valleculae and pyriform sinuses, infiltration of deep-tissue planes, and adenopathy. A 4-mm nodular lesion was not seen on pharyngography. Radiographic evaluation provided supplemental information in six patients, especially regarding inferior extent of disease in four whose bulky lesions precluded adequate visual assessment. CT aided in defining deep-tissue-plane involvement and extent of nodal disease. It is concluded that barium pharyngography and CT are useful in the diagnostic evaluation of possible Kaposi's sarcoma in patients with AIDS and dysphagia.
艾滋病患者胃肠道卡波西肉瘤的放射影像学表现此前已有描述，但咽部受累情况鲜受关注。本研究比较了8例艾滋病伴吞咽困难患者咽部卡波西肉瘤的放射影像学表现与喉镜或支气管镜直视检查结果。钡剂咽部造影（6例患者）显示结节状病变，无溃疡，范围从单个结节到广泛融合性病变。CT（2例患者）显示腔内结节状或息肉样突出、会厌谷和梨状窦变形、深部组织平面浸润及淋巴结病。咽部造影未发现一个4毫米的结节状病变。放射影像学评估为6例患者提供了补充信息，特别是对于4例因病变较大无法进行充分直视评估的患者，明确了疾病的下延范围。CT有助于确定深部组织平面受累情况及淋巴结病变范围。结论是，钡剂咽部造影和CT对艾滋病伴吞咽困难患者可能的卡波西肉瘤诊断评估有用。
