Histiocytic Sarcoma with Central Nervous System Involvement in Dogs: 19 Cases (2006–2012)

Abstract

Breed predispositions appear to vary from reports of HS in other organ systems. Some unique imaging and clinicopathologic characteristics, particularly brain herniation, profound meningeal enhancement, and pleocytosis in combination with 1 or more mass lesions, might help to differentiate this neoplasm from others involving the CNS, although this requires further study.
