CT Findings of Palpable Neck Masses in Children
Abstract
- PURPOSE
We performed this study to assess the value of CT in the differential diagnosis of palpable neck
masses in children.
MATERIALS AND METHODS
We retrospectively reviewed the CT scans of the palpable neck masses in 30
children. The masses were proved histopathologically and classified into cystic, solid, and inflammatory mass and
their CT findings were analyzed.
RESULTS
Twelve cases were cystic masses, 4 were solid masses, and 14 were inflammatory lesions. Cystic
masses included cystic lymphangiomas (n=6), branchial cleft cysts (n=3), thyroglossal duct cysts (n=2), and
ranula (n=l). Cystic lymphangiomas showed insinuating appearances into adjacent structures and 4 cases
occurred in the posterior cervical space. All branchial cleft cysts were round cystic masses with smooth wall and
displaced the submandibular gland anteriorly and the sternocleidomastoid muscle posteriorly. Two thyroglossal
duct cysts occurred centrally adjacent to the hyoid bone and 1 ranula in the submental area. Solid masses were
juvenile hemangioma, pleomorphic adenoma in submandibular gland, neurilemmoma, and fibromatosis colli.
Juvenile hemangioma showed well-enhancing mass with indistinct margin and the other solid masses had
well-defined margin with their characteristic location. Inflammatory lesions were abscess (n=4), deep neck
infections with lymphadenopathy (n=4), submandibular gland inflammation (n=3), and tuberculous lymphadenitis
(n=3) and they showed strand-like enhancement in adjacent subcutaneous tissues. Tuberculous lymphadenitis
had multiple lymph node enlargement with internal low attenuation areas and showed less surrounding
strand-like enhancement than suppurative lymphadenopathies.
CONCLUSION
Most neck masses in infants and children were of congenital or inflammatory origin. CT is
useful for the evaluation of the child presenting with a neck mass, because it can differentiate various forms of
neck masses and is able to reveal the relationship of the masses to the adjacent structures with their
characteristic location.
