Meningioangiomatosis in the brain stem of a dog.
Meningioangiomatosis (MA) is a malformation of the vasculature of the central nervous system, characterized by the proliferation of meningothelial cells around blood vessels. MA has been reported, albeit rarely, in main, cattle and dogs. This paper records a case of MA affecting the brain stem in a 9-year-old male dog, and provides histochemical and immunohistochemical evidence for a perivascular fibroblast-like cell origin of the proliferating cells.
