Branchial cleft cyst

Origin

Branchial cleft cysts, or branchiogenic cysts, are formed by residual branchial clefts that remain from embryonic development.

Symptoms

Branchial cleft cysts usually cause symptoms in older children or in adults. They are slow-growing and cause painless neck swelling.

Diagnosis

The goal is to examine the lesion in the consult office with an ultrasound or CT scan to visualise the cysts. Puncturing the cyst with a needle results in the discharge of a characteristic greenish fluid.

Treatment

So long as there are no symptoms, a ‘wait-and-see’ approach is appropriate. In case of bothersome drainage or infections, the cysts may be surgically removed.
