Branchial cysts in the parotid gland are rare. Among 392 parotid masses which we examined and operated on during the past 15 years and 7 months in our hospital nine were branchial cysts. All were identified as second branchial cysts. Ultrasonography showed a septum structure in two of the cysts. Although ultrasonography and magnetic resonance imaging (MRI) provide useful information in the diagnosis of cysts, those which contain non-serous materials are sometimes misdiagnosed as solid tumor.
