Hello everybody. New member here. I have a question about this case. Cat, European Shorthair, FS, 12 years, progressive paresis posterior towards paralysis posterior in 3 weeks. Besides the abnormal vertebrae Th10-Th11, can anybody enlighten me on the calcification-like string at the heart on the SD (lateral) position. Cat is put asleep now. But this string like thing, keeps me wondering what it might be.
