Deltoid muscle atrophy
in Health ·
Before I get into the details about my testing in San Francisco, I gotta touch on those DNA results and that whole CCTT thing from back in July 2012.
It says this: "DNA shows a homozygous deletion of the SMN2 gene. Other requested lab findings are within physiological limits. CCTT shows anisotropy with hypothermia in the right hand and fingers in the C6-C7 dermatom.
A homozygous SMN2 deletion predisposes one to lower motor neuron syndrome and is found in 5-9% of control subjects. Asymmetric anisotropy in the right hand indicates involvement of autonomic fibers."
Alright, enough about that. Let's talk about the San Francisco tests.
The big goal here? Ruling out any kind of motor neuron disease.
They ran the works: blood work, EKG, EMG, ultrasound of the right axilla, chest X-rays, and an MRI of my cervical spine.
Long story short: motor neuron disease is off the table.
I'll focus mostly on the EMG and the MRI (the latter looks fine).
The EMG shows a moderate, chronic lesion in the upper trunk of the right brachial plexus. It also shows some mild, distal polyneuropathy in my legs. (I haven't mentioned my legs in this thread before because they don't really bother me. Back in April last year, at Mayo Clinic, they flagged some minor nerve fiber damage in my feet).
The cervical spine MRI (T1, T2, and STIR in sagittal; T1 and T2 in transverse) shows the cervical vertebral bodies have normal height, position, and signal intensity. The dorsal intercorporeal line and lordosis are maintained. The intervertebral disc at the C7-Th1 segment has normal height but shows altered signal intensity due to degenerative changes.
In both sagittal and transverse views, there's a small disc bulge at the C6-C7 segment, which slightly narrows the anterior epidural space. The lateral recesses are clear, the right neural foramen is narrowed, and the left one is normal. No signs of herniated discs anywhere in the cervical spine.
In the sagittal view, at the Th4-Th5 level, there’s a small subligamentous disc protrusion positioned right-preforaminally, narrowing the anterior epidural space and causing slight compression on the spinal cord. The spinal canal width is normal. Across all cervical segments, the right neural foramen is tight while the left stays open. The spinal cord itself looks normal in shape and signal. The craniocervical junction looks fine too.
Final verdict: go exercise.
