Cavernous hemangioma of the larynx is an uncommon, difficult-to-diagnose vascular tumor for which there is no significant imaging literature to date. The possibility of improved diagnosis through RBC scanning might obviate injudicious biopsy and potential hemorrhage within the airway. Utilizing the radionuclide RBC scan, which labels the patient's own RBCs initially with cold pyrophosphate, and subsequently with technetium 99m as pertechnetate, we have identified successfully four patients with cavernous hemangioma of the larynx. All presented with a supraglottic mass involving at least the aryepiglottic fold and arytenoid region unilaterally. This report describes our satisfactory diagnostic imaging experience with the radionuclide RBC scan and suggests both its imaging specificity and its role in the management of this lesion.
喉海绵状血管瘤是一种罕见且难以诊断的血管肿瘤，目前尚无重要的影像学文献报道。通过红细胞扫描改善诊断的可能性或许可以避免不明智的活检以及气道内潜在的出血。利用放射性核素红细胞扫描，该扫描最初用焦磷酸冷标记患者自身的红细胞，随后用高锝酸盐形式的锝99m进行标记，我们已成功确诊4例喉海绵状血管瘤患者。所有患者均表现为声门上肿物，至少单侧累及杓会厌襞和杓状软骨区域。本报告描述了我们使用放射性核素红细胞扫描获得的令人满意的诊断成像经验，并表明了其成像特异性及其在该病变管理中的作用。
