To illustrate the main types of cysts affecting the region of the head and neck identified through US,
and MRI. To identify the main findings in the image that differentiates benign and malignant cystics lesions.
The diagnostic modalities used to study the changes affecting the head and neck are: ultrasonography (US), computed tomography (CT) and magnetic resonance imaging (MRI). Other diagnostic modalities include positron emission tomography associated with computed tomography (PET-CT) and nuclear medicine examinations. The methods discussed here will be CT and MRI . Some cases of head and neck cysts were evaluated with the following locations that we will show : - Second branchial cleft cyst (2...
Findings and procedure details
Second branchial cleft cyst These are the most common branchial anomalies. They may present as cysts or fistulas,
opening along the anterior border of the sternocleidomastoid muscle,
in their middle third. There may be complete,
incomplete internal and incomplete external fistula. The path follows the carotid sheath,
crossing the hypoglossal nerve and reaching the pharyngeal tonsil.
Incomplete internal fistula is the rarest. Cysts are classified according to Proctor in four...
Head and neck cystic lesions have a wide variety of benign and malignant processes. The findings of the lesion image along with the clinical history are fundamental to narrow the differential diagnosis in order to indicate adequate therapy,
surgical planning and adequate follow-up of the disease. US continues to be the first diagnostic method and the most available technique,
however it is an operator-dependent method. For better soft tissue evaluation , CT was performed with contrast or MRI .
