Cervical thymic cysts are not very common. Two-thirds of the lesions are detected in the 1st decade of life, when the thymus is biggest in size and most active. The remaining one-third in the 2nd and 3rd decades. Due to its rarity, cervical thymic cyst is seldom included in the differential diagnosis of a neck mass. Approximately 90 cases have been reported thus far, and most of these cases have occurred asymptomatically in children and adults. We report a case of a 44-year old man with a cervical thymic cyst mimicking branchial cleft cyst.

The fourth branchial clef cyst is very rare entity ana only 35 cases have been reported worldwide. There have been some controversial attempts to prove its anatomical route through embryological background. However some reports even suggested that it might be impossible to prove its entity anatomically Recently, reports are coming out on the diagnostic approaches using anatomical pathway. We experienced in 45 years old woman, one case of lateral cystic neck mass which were anatomically presumed to be fourth brachial cleft cyst.
