A Surgical Case of Canine Frontal MeningiomaMotoji MOROZUMI*, Kazuyuki UCHIDA, Hitoshi MAKINO,Norio SAITO, Atsuko SAITO and Masato KUWABARA
SUMMARY A 4-year-old male setter dog weighing 20 kg with depression, intermittent severe generalized seizure
and circling to the left, was neurologically revealed to have exaggerated reflexes of both patellar tendons
and elevated protein content and total cell count in the cerebrospinal fluid (CSF). The CSF Pandyユs test
was positive, and magnetic resonance images demonstrated an irregular shaped mass, approximately 30 mm
in diameter, in the left forebrain. The surgically removed mass histopathologically consisted of proliferated
small spindle-shaped cells with whorl arrangement and occasional psammoma bodies, and was diagnosed as
meningioma. The case was getting better, but he died of status epilepsy 5 months after the operation.
