Hi,
i came across a qeustion asking about a structure in an upper thorax ct scan in patient having unequal pupils?
now it can be horner syndrome where cervical plexus is involved but where to find it on the ct.

not exactly thorax......it's T1 vertebrae tht give rise to preganglionic fibers tht ascend up to synapse with the ganglion which is present at the root of the neck......
ofcourse i can't say much unless i see tht ct!
where is this q from....qbank?

There is some thoracic structures where you can produce horner syndrome:
T1, due to some sympathetic fibers arise from T1,
Carotid artery, even being a cervical structure, it has its origin in the upper mediastinum, and sympatetic fibers travel along carotid artery and its branches through the head and neck.
I think that cercival ganglions are structures that carry sympathetic fibers but I have never seen them in a CT

In Horner's syndrome, it is important to exclude pathological process such as
tumour in the pulmonary apex. Once this is excluded you can look for other causes.

My doubts about distinguishing of cervical ganglion on CT. We can see nerves sometimes on MRI 3D. Often a look at arteries supplying the brachial plexus gives the needed information. www.tosinfo.com
Key as earlier was said is tumor of lungs, Puncoast tumor.
