General & Family Physician,  's  Response
Hello,

By what you explain the sensation loss of this patient is likely due to problems with the thoracal nerves which are responsible for the sensation of the skin on the side from the anterior line in the middle of the chest and abdomen to the posterior line over the spine.

Tests like MRI or CT scan are needed to determine the cause of this loss of sensation. It can be due to opposite side brain lesion responsible for the sensation in the area or can be due to same side lesion of the spine. MRI of the spine and brain can tell more of the location of the problem and the nature of the condition causing it.

Hope I have answered your query. Let me know if I can assist you further.

Regards,
Dr. Antoneta Zotaj, General & Family Physician
