Unilocular cervical lymphatic cyst in an adult

Characteristic imaging findings in lymphoceles of the head and neck

OBJECTIVE

Lymphoceles are benign neck cysts that are important to differentiate from congenital, infectious, and malignant cystic neck masses because they require unique surgical treatment and follow-up. We reviewed a series of surgically proven lymphoceles to delineate the radiologic characteristics of lymphoceles that differentiate them from other cystic neck masses.

MATERIALS AND METHODS

A search of radiology report impressions for the terms "lymphocele" and "lymphatic cyst" was performed on all neck CT, MRI, and sclerotherapy studies from January 2003 to December 2009 at our institution. Clinical and pathology records were searched for the same terms to identify additional cases. Medical records confirmed diagnosis. Study images were reviewed on PACS to assess cyst location and imaging characteristics.

RESULTS

There were nine patients (six women and three men; age range, 22-85 years; mean age, 50.1 years) with 12 pathologically proven lymphoceles on six contrast-enhanced CT and three contrast-enhanced MRI examinations. Lymphoceles were located in the posterior cervical space in 12 of 12 and supraclavicular in 10 of 12 cases. Lymphoceles were unilocular nonseptated cysts in 12 of 12, fluid density or signal in 11 of 12, nonenhancing in 12 of 12, and lacked a cyst wall in eight of 12.

CONCLUSION

Lymphoceles are rare unilocular cystic neck masses that may mimic other congenital, infectious, and malignant neck cysts. When enhanced CT or MRI shows a unilocular, nonseptated, fluid density or intensity, and nonenhancing supraclavicular cyst in the posterior cervical space, lymphocele is an important part of the differential diagnosis. Atypical features warrant fine-needle aspiration or follow-up for confirmation.

Thoracic duct cyst: sclerotherapy as alternative for surgical treatment

BACKGROUND

Thoracic duct cysts of the cervical portion are rare benign lesions for which surgery is the treatment of choice.

METHODS

We present 2 cases of a thoracic duct cyst of the cervical portion. One patient was treated by surgery and the other patient by ethanol sclerotherapy.

RESULTS

After establishing diagnosis by radiologic assessment and chemical and cytological fine-needle aspirate of the cystic masses, both patients were treated successfully.

CONCLUSION

Ethanol sclerotherapy provides an alternative therapy for thoracic duct cyst when evaluation establishes a high likelihood of clinical diagnosis.

Left Cervical Chyloma following Right Thyroidectomy

Cervical chylomas are rare entities, as only four cases have been previously reported. All of these previous cases involved the left side, all were related to the thoracic duct, and all occurred following trauma or surgery. We report a new case of a left-sided chyloma that was unusual because it arose following a right-sided subtotal thyroidectomy. The chyloma arose as a left supraclavicular mass within 3 months of the thyroidectomy, and it slowly enlarged over a period of 9 years. Following evaluation by computed tomography, the mass was excised, and the patient recovered uneventfully. We also review what is known about the diagnosis and treatment of cervical chylomas.
