CT Neck Lymphadenopathy

TECHNIQUE: Routine transverse CT images through the neck after the IV administration of nonionic contrast with coronal and sagittal reformations.

FINDINGS: A solitary well marginated and homogenously enhancing enlarged level V lymph node is identified within the right clavicular fossa measuring approximately 12 mm in short axis and is best seen on image 61 of 88.
Otherwise, there is no other lymphadenopathy, pathologic mass or fluid collections identified.
The imaged portions of the brain parenchyma are unremarkable.
The demonstrated airway is patent, without abnormal narrowing or filling defects.
Soft tissue planes are normal.
The demonstrated blood vessels and bones are unremarkable.
Incidental note of a small retention cyst is identified within the right sphenoid sinus.

Conclusion: Nonspecific enlarged solitary right level V lymph node within the right clavicular fossa of undetermined significance. We recommend further evaluation with otolaryngology consultation.
Findings: As a consequence of beam hardening artifact from the patient's dental hardware, images #23 through 30 are degraded, limiting evaluation of the oral cavity and perioral soft tissues.
Using lymph node size as the discriminating characteristic, no clinically significant lymphadenopathy is appreciated in the supra or infrahyoid neck. There is no discrete mass lesion. There is atrophy of the left submandibular gland, and mild hypertrophy of the right submandibular gland. A 3 mm round calcification is seen within the right submandibular gland and felt to represent trace atherosclerotic calcification of the mandibular artery. The thyroid gland and parotid glands are normal.The glottic and supraglottic structures are normal. There is atherosclerotic calcification the bilateral carotid bulbs and internal carotid arteries. There is otherwise normal opacification of the large vascular structures. On the bone window settings, the skullbase is intact. There are moderate diffuse degenerative changes throughout the cervical spine. There is a grade 1 anterolisthesis of C7 on T1, likely due to facet degenerative changes. There is near complete disc space loss at the C5-C6 and C6-C7 levels. Large bridging osteophytes are seen at C2-C3 and C4 and C5. Well-corticated osseous fragments are seen anterior to the atlantoaxial articulation.
There are diffuse emphysematous changes of the lung apices. There is biapical scarring and fibrotic changes. A 1.4 mm spiculated nodule is seen within the left lung apex, and better evaluated on the CT of the chest from the same date.
1. No mass or clinically significant lymphadenopathy is appreciated in the supra or infrahyoid neck. There is atrophy of the left submandibular gland. Uncertain whether mass palpated at superior right neck may represent the mildly hypertrophied right submandibular gland.
2. Diffuse degenerative changes of the cervical spine.
3. Atherosclerotic calcification of the carotid arteries.
