Branchial cleft cysts are congenital epithelial-lined cystic lesions in the neck originating anywhere from the level of the mandible (first branchial cleft) to the supraclavicular region (fourth branchial cleft). These can become superinfected and present as an acutely enlarging neck mass Congenital anomalies of the fourth branchial complex are very rare lesions. Although both have been reported, fistulous tracts are more common than cysts. Occasionally, branchial cleft cysts have been described in the mediastinum. These cysts may represent either fourth or sixth branchial vestiges. If the cyst is located under the aorta, it.

We report a unique case of a fourth branchial cleft cyst found within the thymus of an adult patient. In the literature to date, there have been no reports of such a finding in the adult population. These anomalies can often cause recurrent acute suppurative thyroiditis or recurrent deep neck absces Fourth branchial cleft cysts. Fourth branchial cleft anomalies are very rare lesions, representing 1% to 4% of all branchial cleft anomalies. 73,74 These lesions typically present during early childhood, much like third branchial cleft anomalies, typically secondary to superimposed, acute, suppurative thyroiditis, or recurrent abscess formation. The second, third, and fourth branchial clefts merge to form the sinus of his, which will normally become involuted. When Sinus of His is not properly involuted, a branchial cleft cyst forms. Second branchial cleft cysts are cystic dilatations of the remnant of the 2 nd branchial apparatus, and along with 2 nd branchial fistulae and sinuses. Twenty-one patients had a branchial cleft cyst, and 29 patients showed malignant cystic adenopathy confirmed by pathology . Figures 2 and 3 show examples of findings seen in the two populations. The branchial cleft cyst population had 11 men and 10 women as compared with the 15 men and 14 women in the malignant population (p = 0.96)

Fourth branchial cleft cysts are particularly rare, accounting for less than 3% of all branchial anomalies . Removal of the cyst is necessary to prevent infection and obstruction. Treatment for a fourth branchial cleft cyst has typically been complete surgical excision, but other modalities have also been reported [2,3]. 2. Case descriptio An infected third branchial cleft cyst should be considered if a patient presents with an abscess in the posterior triangle of the neck. A fourth branchial cleft fistula/sinus tract arises from the pyriform sinus apex and descends inferiorly to the mediastinum in the path of the tracheo-oesophageal groove [13, 17] A fourth branchial fistula arises from the lateral neck and parallels the course of the recurrent laryngeal nerve (around the aorta on the left and around the subclavian artery on the right), terminating in the apex of the pyriform sinus; therefore, fourth branchial cleft cysts arise in various locations, including the thyroid gland and. Fourth branchial sinus. Acute managment. 1. Introduction. Branchial malformations are common congenital head and neck lesions, usually diagnosed in childhood, during the first decade of life.

Author Alexis Saadoun 1 Affiliation. A fourth branchial cleft cyst typically presents as a low anterior neck mass, beneath the platysma and anterior to the sternocleidomastoid muscle. The tract of a fourth branchial cleft cysts loops around cranial nerve XII then runs posterior to the common carotid artery and thyroid following the recurrent branch of cranial nerve X However, failure of complete wall fusion can result in branchial cleft cyst, sinus, or fistula and, depending on the area of the branchial arch, can be classified into type 1, 2, 3, or 4 (see Fig. 14.1B). The first branchial is the only cleft that will become a definitive structure, eventually giving rise to the epithelium of the external.

Branchial cleft anomalies may be presented as branchial cysts, fistulas, or sinuses. Purpose of this paper is to present the diagnostic procedures and the treatment in a series of branchial cleft cysts. Eighteen patients with branchial cleft cysts were surgically treated. All of them were subjected in laboratory examinations with ultrasonography, CT or/and MRI, and fine needle aspiration. 1st Branchial cleft cyst. 1st cleft cysts make up approximately 5-25% of all branchial cleft anomalies.

These typically present lateral to the facial nerve and end within the external. Third and fourth branchial cleft cysts and sinus tracts. Third and fourth branchial cleft cysts occur in the lower lateral neck. The external sinus tract opening will be in the lower lateral neck below the thyroid and cricoid cartilages, just anterior to the SCM muscle. If there is an internal opening, it will be deep within the throat in a.

Introduction. Branchial cleft cysts are the second most common pediatric head and neck masses, with patients most often presenting to medical attention between the ages of 11 and 30 .Other branchial abnormalities including fistulas and sinuses present much earlier in life .Branchial cleft cysts are caused by the failure of involution of normal embryological structures Branchial cysts appear most often as unilateral neck masses and account for 25% of head and neck congenital swellings, of which 95% arise from the second branchial cleft.

Branchial cleft cysts (BCCs) are both the most common cysts to arise in the neck and the most common congenital masses of the lateral neck (1-6).Other common benign cystic lateral neck masses that can mimic BCCs include thyroglossal duct cysts, ectopic thymic cysts, lymphangiomas, dermoid and epidermoid cysts, and cystic nerve sheath tumors (3, 4) First branchial cleft cysts are subdivided base upon location: type I cysts are located near the external auditory canal usually inferior, posterior and medial to the tragus/pinna. All types of 1st branchial cleft cysts are intimately associated with the facial nerve and the parotid gland BACKGROUND AND PURPOSE: Previous reports have suggested that second branchial cleft cysts (BCCs) appear on sonograms as well-defined, cystic masses with thin walls and posterior enhancement. Previous CT and MR imaging findings, however, have indicated heterogeneity of these masses, and, in our experience, sonography also shows a similar variable appearance
