How is a branchial cleft cyst diagnosed?

A physical exam is usually enough to diagnose a branchial cleft cyst. Sometimes, MRI or CT scans can check the exact location of the cyst. Ultrasounds can also help figure out whether there is a fistula (unusual connection between two organs) connecting the throat or ear canal.

When do branchial cleft cysts present?

Branchial cleft cysts and sinus are congenital conditions (conditions present at birth) caused by unexpected changes during pregnancy. Often, these changes occur around the 5th week of pregnancy, when gill-like structures around the neck do not reabsorb back into the skin.

How can you tell the difference between cystic hygroma and branchial cyst?

Dermoid cysts occur in the midline and differ in location from the cyst in the present case. All these lesions differ in microscopic features from branchial cleft cyst. Cystic hygroma occurs in the posterior triangle of the neck that is posterior to the sternocleidomastoid muscle.

Where is branchial cleft cyst located?

Also, known as a cleft sinus, a branchial cleft cyst is a lump that develops in the neck or just below the collarbone. Branchial cleft cysts form during development of the embryo. They occur when tissues in the neck and collarbone area (branchial cleft) fail to develop normally.

What is a second branchial cleft cyst?

Second branchial cleft cysts are benign developmental cysts thought to arise from congenital remnants of the second branchial arch. Other branchial anomalies exist but are much less common than second cleft anomalies which represent >95 % of all branchial cleft anomalies [1, 2].

What is First branchial cleft?

First branchial cleft cysts develop as a result of incomplete fusion of the cleft between the first and second branchial arches and give rise to two distinct anomalies, termed type I and type II anomalies. Type I anomalies are purely ectodermal while type II anomalies exhibit ectodermal and mesodermal elements.

What is 2nd branchial cleft cyst?

What is inside a branchial cleft cyst?

Branchial cleft cysts are lined with stratified squamous epithelium and may contain keratinous debris inside the cyst. In some cases, the cyst wall is lined by ciliated columnar epithelium resulting in more mucoid contents. Lymphoid tissue is typically present surrounding the epithelial lining.

How rare is branchial cleft cyst?

The exact incidence of branchial cleft cysts in the US population is unknown. Branchial cleft cysts are the most common congenital cause of a neck mass. An estimated 2-3% of cases are bilateral. A tendency exists for cases to cluster in families.

What are branchial clefts?

A branchial cleft abnormality is a cluster of abnormally formed tissue in the neck. A branchial cleft abnormality is a birth defect. It happens when the area does not form as it should during the early stages of an embryo’s development. Branchial cleft abnormalities are diagnosed by a physical exam.

What is First branchial cleft sinus?

First branchial cleft cysts occur just in front (of) or below the ear at the angle of the jawline. The external sinus tract opening can be above the jawline (type I) or below the jawline in the upper neck above the level of the hyoid bone (type II). If there is an internal opening, it will be inthe ear canal.

What does a branchial cleft cyst feel like?

The signs of a branchial cleft cyst include: a dimple, lump, or skin tag on your child’s neck, upper shoulder, or slightly below their collarbone. fluid draining from your child’s neck. swelling or tenderness in your child’s neck, which usually occurs with an upper respiratory infection.

What is the sonographic pattern of second branchial cleft cysts?

CONCLUSION: As previously suggested by CT and MR imaging findings, sonography reinforces that second BCCs in adults are not simple cysts but have a complex sonographic pattern ranging from a typical anechoic to a pseudosolid appearance. Second branchial cleft cysts (BCCs) present clinically as a soft-tissue swelling in the anterior neck.

What is a congenital cyst on the neck?

Congenital neck masses are developmental anomalies typically seen in infants or children. Common conditions include thyroglossal duct cysts, branchial cleft cysts, and cystic hygromas.

Where is the second branchial cleft sinus located?

Second branchial cleft sinus or fistulas, on the other hand, present earlier. Fistulas extend from the skin surface anterior to the middle of the sternocleidomastoid muscle, pass between the internal and external carotid arteries and eventually drain into the tonsillar fossa.

What kind of cancer can be found in a second branchial cyst?

Differential diagnosis. paramedian thyroglossal duct cyst. cystic lymph nodes necrotic nodal metastases, especially squamous cell carcinoma and papillary thyroid cancer. tuberculous adenitis. vascular lesions jugular vein thrombosis. mycotic aneurysm of the neck. neurogenic tumors schwannoma. neurofibroma.
