Laryngeal saccular cyst : A case report

Abstract

We examined a case of a 46-year old Japanese female who had a lateral type of saccular cyst. The patient noticed a painless swelling in the left lateral part of her neck and an abnormal feeling in her throat. A fiberoptic examination revealed swelling along the left aryepiglottic fold to the left false cord. An MRI scan exposed a retention cyst in the larynx extending from the foramen of the superior laryngeal bundle in the thyroid membrane to the upper portion of the anterior cervical triangle. Using an external approach to the neck, the cyst was totally removed. A histopathologic study revealed that the cyst was lined mainly by cuboidal epithelium and partially by squamous epithelium. Based on clinical findings by image analysis as well as histopathology of the larynx, we concluded that it was a saccular cyst of the larynx. The patient's postoperative course was uneventful without any recurrence for one and half of the years.
