1. Advantages of ultrasound imaging include:A. Imaging modality of choice for thyroidB. Doppler sonography can be used for
assessment of blood flowC. Scanning in the sagittal plane offers
optimal visualizationD. A and BE. All of the above
2. Features suggestive of malignancy in a thyroid nodule include all of the following EXCEPT:
A. HyperechoicB. MicrocalcificationsC. Increased blood flow on DopplerD. Tail shapeE. Irregular border
3. Parathyroid imaging on ultrasound:A Is less accurate than sestamibi scans in
localizing a solitary adenomasB. Normal parathyroid glands can be visualized
with high resolution ultrasonographyC. Parathyroid adenomas are hyperechoic
relative to the thyroid glandD. Superior parathyroid glands are on a deeper
plane than the inferior glandsE. Ectopic parathyroid gland may be visualized
on ultrasound in the posterior mediastinum
4. Ultrasound imaging of salivary glands:A. Is useful for differentiating sialadenitis
from neoplasms and lymphadenopathyB. Is useful for imaging deep lobe parotid
tumorsC. Shows similar echogenicity to the thyroidD. A and CE. All of the above
5. Ultrasound characteristics of salivary malignancies include:
A. CalcificationsB. Smooth shapeC. Increased vascularity on Doppler
imagingD. Ovoid lesion with short axis less than 5
mmE. Homogeneous echostructure
6. Ultrasound imaging for head and neck cancer:A. Can detect metastatic lymph nodes not
detected by CT or MRIB. Round shape of lymph node suggests
malignancyC. Intranodal cystic degeneration suggests
malignancyD. Can be used to avoid elective neck
dissection in NO necksE. All of the above
7. Ultrasound-guided fine needle aspiration:
A. Is done using a 27 gauge needleB. Aspiration is performed firstC. Bevel of the needle is pointed away from
the transducerD. Needle should be irrigated with fixative
prior to insertionE. The needle should be used to shave cells
along the needle path
Punctate echogenicities in thyroid nodules.

8. Normal paraganglia contain all of the following EXCEPT:
A. Sustentacular cellsB. Cells which stain positively with S-100C. Schwann cellsD. Chief cellsE. Catecholamine-containing cells
9. The following is true about paragangliomas:
A. The most common type is the pheochromocytoma
B. 10% occur in the head and neckC. Secretion of epinephrine from head and
neck paragangliomas may occurD. Vagal paragangliomas are more common
than jugulotympanic paragangliomas.E. Familial paragangliomas occur in MEN 1,
Carney’s triad, and von Hippel-Lindau disease
10. Carotid body tumorsA. A positive Fontaine’s sign indicates
movement of a lateral neck mass laterally but not vertically
B. Increased mitotic rate and capsular invasion indicate malignancy
C. Malignancy is determined by histologyD. Diagnosis can be made radiographically
by posterior displacement of the internal and external carotid arteries
E. Classification of tumors is based on size
11. Recommended treatment of carotid body tumors:A. Requires preoperative embolization before
surgical removalB. Results in permanent cranial nerve
deficit(s) in 50% of casesC. Observation is an option for some patients
with carotid body tumors.D. Radiation therapy can reduce the size of
the tumor.E. Surgical resection is preferred over
radiation therapy for multicentric tumors
12. Vagal paragangliomas:
A. Arise from the inferior vagal ganglionB. Arise from the nodose ganglionC. Arise from the jugular ganglionD. A and BE. All of the above
13. Peripheral nerve neoplasms:A. Neurofibromas are encapsulated and may
occur singly or multiplyB. Schwannomas most commonly occur in the
head and neck regionC. Antoni type A areas contain loosely
arranged hypocellular zonesD. Malignant transformation is more common
in multiple neurofibromas than in solitaryE. Cranial neuropathies are rare following
resection of schwannomas
14. Metastatic disease to the neck:A. Location of the metastatic node in level 5
are most commonly associated with a hypopharyngeal primary
B. Fine needle aspiration biopsy diagnosis of adenocarcinoma indicates a primary in a salivary gland
C. The most common distant site to metastasize to the neck is from a lung primary
D. B and CE. All of the above
15. Sarcomas of the neck:A. 80% of head and neck sarcomas are derived
from soft tissues of the neckB. Occur most commonly in childrenC. Staging for bone sarcomas is based on sizeD. Staging for soft tissue sarcomas is based
on site of originE. The most common sarcoma in the head and
neck is the malignant fibrous histiocytoma
16. Rhabdomyosarcoma
A. Accounts for 50% of sarcomas in all age groups
B. Most common site in the head and neck is in the neck
C. Metastatic disease is present in 80% of cases at presentation
D. Primary treatment is surgical resectionE. Highest incidence occurs in first decade
of life
17. Rare sarcomas of the neck:
A. Osteosarcoma of the mandible frequently metastasizes to the neck
B The most common site of fibrosarcoma in the head and neck is in the neck
C. Alveolar soft part sarcoma is associated with the fusion gene ASPL-TFE3
D. Epithelioid hemangioendothelioma exhibits extremely aggressive behavior
E. Liposarcoma is the most common soft tissue sarcoma in the head and neck in adults
18. Rarer sarcomas of the neck:A. Malignant hemangiopericytoma (MPC) arise
from the cells of Zimmerman, around capillaries and postcapillary venules
B. Majority of HPCs occur in the paranasal sinuses
C. Malignant peripheral nerve sheath tumor (MPNST) can occur either spontaneously or with NF-1
D. MPNST has recurrence rates of more than 40% despite aggressive treatment
E. All of the above
19. Review these before the in-serviceA. Synovial sarcoma
Typically arises in the hypopharyngeal and retropharyngeal region
B. Malignant giant cell tumorRadiation induced after treatment for a benign giant
cell tumor, sinonasal region and mandible most common sites
C. Ewing’s sarcomaDerived from primitive neuro-ectoderm, 2nd most
common bone tumor in children, mandible, maxilla, skull
