title: Adult giant hemangioma of the larynx: a case report.
abstract: We report a giant hemangioma that extended from the mesopharynx to the larynx in an adult. The patient was a 39-year-old woman who had demonstrated an asymptomatic pharyngeal hemangioma since she was 1 year-old. She developed vertigo and consulted a hospital at the age of 39. During screening by head MRI for the diagnosis of the vertigo, hemangioma of the laryngopharynx was detected. She was referred to Osaka National Hospital for further examination. Her subjective symptoms were dyspnoea in the lower left lateral-position. On observation by nasopharyngolaryngovideoscope, a giant hemangioma was diagnosed in the left mesopharynx expanding into the larynx. On MRI study, hemangioma widely extended to the right posterior wall at the mesopharynx level. Since we were concerned about risk of choking if the hemangioma of the larynx were left untreated, we recommended surgery. Under the general anesthesia, hemangioma of the larynx was light-coagulated by KTP laser through tracheotomy. The postoperative-course has been good and at 9 months postoperatively, there was no progression of hemangioma.
