Abstract

Branchial cleft cysts commonly presents as a solitary, painless mass in the neck of a child or young adults. They usually presentation is in the anterior triangle of the neck, mostly along the upper third. Although very rarely a branchial cyst can present in the posterior triangle of neck. In this article, we present a rare case of a 9-year-old female child with a right branchial cyst who presented with an asymptomatic, rapidly growing mass in the right posterior triangle of the neck extending from mid neck, C5 level superiorly and abutting the right supraspinatous muscle inferiorly. She underwent excision of the cystic mass and the follow up period was uneventful.
