Froin's syndrome – coexistence of xanthochromia, high protein level and marked coagulation of cerebrospinal fluid (CSF). It is caused by meningeal irritation (e.g. during spinal meningitis) and CSF flow blockage by tumour mass or abscess. [1]
Xanthochromism (also called xanthochroism or xanthism), from the Greek xanthos (ξανθός) "yellow" and chroma (χρώμα) "color", is an unusually yellow pigmentation in an animal.
However, Shola, an English Shepherd who was forced to retire as a mountain rescue dog due to the condition, has helped scientists create a new test that could mean the end of PRA.

A dog with degenerative myelopathy often stands with its legs close together and may not correct an unusual foot position due to a lack of conscious proprioception. Canine degenerative myelopathy, also known as chronic degenerative radiculomyelopathy, is an incurable, progressive disease of the canine spinal cord that is similar in many ways to amyotrophic lateral sclerosis (ALS).
Visual examination of the specimen may provide information to the pathologist or the physician. For example, fluid drained from an abscess may appear cloudy, or cerebrospinal fluid obtained by lumbar puncture may exhibit xanthochromia, suggesting a bleed has occurred. Laboratory technologists may provide qualitative descriptions accordingly.
