PM is a rare histological variant of human beings and dogs. In humans, this tumor represents 1.0–2.5 % of all meningiomas and tends to affect younger patients, including children (Russel et al. 1989). Because of its high invasiveness of the brain, recurrence, and metastasis rate, PM is considered grade III in man (Perry et al. 2007). PM has been reported in dogs by Schulman et al. (1992), Summers et al. (1995), and Kaldrymidou et al. (2008), and it is currently included in the group of benign meningiomas in the histological classification of CNS tumors of domestic animals (WHO) (Koestner et al. 1999). In the present study, canine PM presented histological features reported in the human form. However, the tumor did not affect young patients. Dogs older than 7 years were the most affected, in line with the average age of onset for canine meningiomas (Patnaik et al. 1986). Applying the morphological parameters used in grading of human meningiomas (WHO), in our study, PMs were characterized by moderate histological malignancy consistent with grades I and II. Moreover, they occurred mainly in the brain, occasionally associated with brain invasion, as documented in two cases. This tumor showed foci of spontaneous necrosis and neutrophilic inflammation. The proliferation index ranged from low to medium in line with the mitotic index detected by routine histological examination.
