pyrophosphate and Laryngeal-Neoplasms

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.
