A 10-year-old castrated male cat showing behavioral (irritation, prowling, and tumbling) and cutaneous abnormalities such as dermal fragility was diagnosed as hyperadrenocorticism with pituitary macroadenoma, concurrent with insulin dependent diabetes mellitus. Pituitary enlargement (18.0 mm) was observed during magnetic resonance imaging. High endogenous adrenocorticotropic hormone levels (>2,500 pg/ml) were also observed. Although trilostane treatment (5–10 mg/head, daily) was commenced, the clinical signs did not disappear. Insulin and trilostane treatment were discontinued on day 86 after first day of radiation therapy (4 Gy/12 fractions). After radiation therapy, a decreased pituitary tumor size (10.7 mm) was observed on day 301; neurological and dermatological signs exhibited remission. Radiation therapy is the treatment of choice for feline hyperadrenocorticism with pituitary macroadenoma with neurological signs.

A 9 year-old, neutered, male French Bulldog showing cluster seizures was diagnosed with a glioma in the right piriform cortex by MRI. Hypofractionated radiation therapy (RT) was performed using a linear accelerator. Although the lesion had involuted significantly at 2 months after RT, recurrence was observed at 4 months after RT. Chemotherapy was started using CCNU (60 mg/m2 every 6–9 weeks) and was continued for one year. Follow-up MRI revealed involution of the lesion and the intervals of CCNU were increased to every 9–14 weeks. Two years after the first presentation, the dog suffered status epilepticus, followed by deficits of left sided postural reaction with cognitive dysfunction. The dog died on day 910, and histopathological diagnosis confirmed anaplastic oligodendroglioma.
