Hyperthyroid cat (Thyroid Storm)

Hello

I was hoping for some guidance on Emma a 14 year old FS DSH that has been diagnosed with hyperthyroidism but is apparently dispalying all the symptoms of a “Thyroid Storm”.  Radiographs yesterday showed some pleural effusion and pulmonary edema with what appeared to be a small heart.

Hello

I was hoping for some guidance on Emma a 14 year old FS DSH that has been diagnosed with hyperthyroidism but is apparently dispalying all the symptoms of a “Thyroid Storm”.  Radiographs yesterday showed some pleural effusion and pulmonary edema with what appeared to be a small heart.

Today the thoracic US showed what appeared to be a small heart with a moderate amount of pleural fluid. The heart almost appeared as it does when there is PCE present although I did not see any PCE. Cranial to the base of the heart there were 2 elongate circular structures that I do not typically see cranial to the Aorta. They do appear to have blood flow but are almost twice the diameter of the aorta. I first thought it was pleural fluid but Doppler showed blood flow. So I am wondering it is a possible aneurysm or a normal structure.

The cat was fractious and the images we got were the best that we could get. The first is to show the heart. The next few are fanning images to try and capture the heart and areas of concern in one clip.

Any advice on what I am seeing would be greatly appreciated and if anyone knows the pathology of heart failure in a thyroid storm that would be great. Literature indicates that they do not fully understand why cats with a thyroid storm suffer heart failure.

Thanks. Brent.
