A canine case of gliosis with cyst formation in the posterior fossa.
A 5-month-old male Great Pyrenees with symptoms of convulsions, circling, and a head tilt was referred to the Animal Medical Center of Nihon University. On a magnetic resonance image (MRI), a cyst in the posterior fossa was noted and a part of the cyst enhanced by gadoteridol. Based on MRI and clinical findings, the patient was tentatively diagnosed with a cyst formation tumor, and an operation to open the cyst and remove the part enhanced by contrast was performed. Postoperatively, the clinical course was good. Pathologically, the removed tissue was diagnosed as a gliosis with cyst formation.
