Management of Right Neck Mass Identified as Prominent Cervical Vertebrae on Ultrasound

Assessment and Diagnosis

The American College of Radiology suggests that ultrasound findings of "prominent cervical vertebrae without evidence of soft tissue mass" indicate a normal anatomical variant rather than true pathology, especially in the absence of symptoms such as pain, difficulty swallowing, voice changes, or neurological complaints 1, 2
The absence of concerning symptoms like pain, difficulty swallowing, voice changes, or neurological complaints is a key factor in determining that no further investigation is necessary, as these are considered "red flag" symptoms that would necessitate further imaging 1, 3
Bony prominences of cervical vertebrae can be mistaken for masses on physical examination but are recognized as normal anatomical structures by the American College of Radiology 2, 4

The American College of Radiology recommends reassuring the patient that the ultrasound findings represent normal anatomy rather than a concerning mass or lymphadenopathy, and that no additional imaging studies are indicated in the absence of symptoms or "red flag" signs 1, 5
Further imaging would only be warranted if the patient developed "red flag" symptoms such as pain, neurological symptoms, difficulty swallowing or voice changes, or constitutional symptoms like fever or weight loss, as outlined by the American College of Radiology 1, 4

If symptoms were to develop, the American College of Radiology suggests that plain radiographs of the cervical spine would be the first-line imaging modality, with MRI without contrast considered if neurological symptoms develop 1, 2, 6

The American College of Radiology notes that degenerative changes in the cervical spine are common in asymptomatic individuals over 50 years of age and correlate poorly with symptoms, highlighting the importance of not over-interpreting incidental findings 1, 2
Unnecessary imaging can lead to incidental findings that may cause further anxiety and lead to unnecessary interventions, as cautioned by the American College of Radiology 5, 6
The high rate of detected abnormalities in asymptomatic patients makes advanced imaging inappropriate in the absence of symptoms, according to the American College of Radiology 1, 6
