Meningioangiomatosis is a rare proliferative disorder of the central nervous system. It occurs sporadically in dogs and is characterized by a leptomeningeal plaque that extends from the subarachnoid space along the perivascular spaces into the adjacent parenchyma. We describe the clinical presentation, magnetic resonance (MR) imaging and neuropathologic characteristics of two additional dogs with meningioangiomatosis, and document involvement of the thoracolumbar spinal cord, a site not previously described for this condition. MR imaging findings were different from those previously described, most likely reflecting the degree of vascularity and collagen deposition. The MR imaging features of meningioangiomatosis are not specific.
