Differential Diagnosis
- Single most likely diagnosis:
- C7 extended, rotated right, sidebent right and inhalation somatic dysfunction of rib 1 on the right. This diagnosis is the most likely because the patient's presentation of increased tone in the right paravertebral musculature, tenderness to palpation on the right at the C7-T1 articular processes, and the C7 right transverse process being more prominent compared to T1, all point towards a dysfunction at the C7 level with a rotational and sidebending component to the right. The rib 1 somatic dysfunction described as moving freely in inhalation and resisting exhalation also supports an inhalation dysfunction.
- Other Likely diagnoses:
- C7 extended, rotated left, sidebent left and inhalation somatic dysfunction of rib 1 on the right. This could be considered if the examination findings were less clear or if there were additional findings not described that might suggest a left rotation and sidebending at C7.
- T1 extended, rotated right, sidebent right and exhalation somatic dysfunction of rib 1 on the right. Although the primary findings suggest a C7 dysfunction, a T1 dysfunction could potentially present with similar symptoms, especially if the examination focused more on the T1 level or if the patient had a different primary complaint.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.):
- None specifically identified based on the information provided, as the differential diagnoses provided are focused on somatic dysfunctions which are not typically life-threatening. However, it's always important to consider other potential causes of neck and thoracic pain that could have more serious implications, such as vertebral fractures, infections, or malignancies, even though these are not directly suggested by the provided options.
- Rare diagnoses:
- T1 flexed, rotated left, sidebent left and inhalation somatic dysfunction of rib 1 on the right. This diagnosis seems less likely given the patient's presentation, which more strongly suggests a dysfunction at the C7 level with specific characteristics that do not align well with a flexed, rotated left, and sidebent left dysfunction at T1.
