Branchial Cleft Cysts in the Mediastinum

Cyst In Mediastinum – A Rare Case Report

“…The same histological picture is seen in this case. In addition, the presence of xanthomatous response and fibroblastic proliferation in this case, forms the tell tale evidence of chronicity of the cyst Very rarely only had such Branchial cysts been reported in the literature (4,5) . Existence of this entity came in literature only after a case report in 1969.…”

Fourth branchial arch anomaly: a rare incidental finding in an adult

“…These are all invariably associated with a connection to the left piriform fossa. To our knowledge no complete fistula has been reported and only one report of a fourth branchial cleft cyst has been made (Montgomery, 1973), although this was found in the mediastinum and may well have been an incomplete sixth pouch remnant or a bronchial cyst (Downey and Ward, 1969). In most reported cases of fourth arch anomalies there is an internal opening beginning at the apex of the piriform sinus (Narcy etal., 1988), usually ending in the perithyroid space or the thyroid gland itself.…”

Branchial cleft cyst arising in posterior mediastinum: A case report

“…The most common clinical presentation in patients with bronchial cleft cysts is a non-painful neck lump on the left side along the anterior border of the SCM (6). Similar to other mediastinal masses, branchial cleft cysts in the mediastinum can produce the same compression symptoms, such as pushing the esophagus and trachea causing dysphagia or respiratory distress.In William's study,he considered that all the mediastinal branchial cleft cysts started from the fourth branchial cleft (7). Therefore, the most common clinical manifestations of fourth branchial cleft cysts, namely recurrent neck abscesses and acute suppurative thyroiditis, can also be observed (8).…”
