Description: Dentists are responsible for the diagnosis of abnormalities involving both hard and soft tissues in and around the oral cavity. In addition to a clinical examination, the radiographic evaluation will often highlight abnormalities within the radiographic field. A relatively uncommon radiographic abnormality is calcification of lymph nodes, which may be associated with a number of pathologic processes, both local and systemic. We present and discuss lymph node calcifications and the diagnostic considerations associated with them in order to assist practitioners in managing their patients appropriately.

1. Pick the INCORRECT statement:

a. Although calcified lymph nodes may not require treatment, they may indicate a significant disease process
b. Calcified lymph nodes are a relatively common finding on routine panoramic radiographs
c. The general dentist is responsible for interpretation of the entire panoramic radiograph
d. A patient diagnosed with calcified lymph nodes should be referred to a physician

2. Radiographic presentation of calcified lymph nodes is most often described as all EXCEPT:

a. Single or multiple irregular-shaped calcifications
b. Calcifications with varying degrees of opacity
c. Moderate sized radiolucencies with mixed radiopacities
d. Clustered and irregularly shaped radiopacities with mixed density or multiple small radiopacities

3. Lymph node calcifications should be differentiated from non-nodal calcifications in the neck such as:

a. Traumatic bone cyst
b. Tonsillolithiasis
c. Fecalith
d. Cholelithiasis

4. Infectious diseases associated with lymph node calcification include all EXCEPT:

a. Tuberculosis
b. Disseminated Pneumocystis Carinii infection
c. Histoplasmosis
d. Rubeola (measles)

5. Non-infectious causes of lymph node calcification may be due to all EXCEPT:

a. Amyloidosis
