cysts rarely occur together with PTC.
Cervical thymic cyst is a rare entity with just over a 100 cases reported.1 It presents as a diagnostic challenge as it mimics lymphangioma and branchial cleft
cyst which are relatively more common in the paediatric age group.
Cystic lesions of head and neck can be routinely diagnosed with conventional MRI sequences, but in certain situations such as infected branchial cleft
cysts or epidermal cysts, DWI can play an important complementary help.
The structures that develop from the first branchial cleft
are the cavum conchae, external auditory canal, and outer layer of the tympanic membrane.

cyst as the initial impression of a metastatic thyroid papillary carcinoma: two case reports," The Kaohsiung Journal of Medical Sciences, vol.
Cystic swellings of the neck in adults are commonly 132#presumed to be second branchial cleft
Incision and drainage are often selected for the initial treatment of infected branchial cleft
cysts; however, these have been shown to have high recurrence rates .
There was a fine tubular shadow in the local lesion, interlinking with cysts, which was suggestive of a first branchial cleft
fistula with cysts.
(1) The differential diagnoses for the contents are as follows: metastatic disease, lymphoma, adenitis, obstructed submandibular duct, salivary gland tumors, abscess, Ludwig's angina, thyroglossal duct cyst, hemangioma, lymphangioma, dermoid/epidermoid, diving ranula (complex), second branchial cleft
cyst (more common in children) (Figure 16).
Cyst--Caused by the incomplete closure of the sinus tract during embryonic life.
Lesions may resemble a pyogenic granuloma, actinomycosis, a thyroglossal duct cyst, a branchial cleft
cyst, a furuncle, a squamous cell carcinoma and an epidermal cyst (1).
Based on topography and the histopathologic and immunohistochemical results, the masses were determined to be a second branchial cleft
cyst for the first case and a second branchial pouch cyst for the second case.
Diagnosis in adults is considered to present a greater challenge than in children and initial misdiagnosis, frequently as branchial cleft
cysts as in the case reported here, is common.
The patient underwent excisional biopsy of the right neck mass, with a clinical diagnosis of branchial cleft
anomalies are some of the most common types of congenital neck masses.
