RESUMO
Degeneração olivar hipertrófica resulta de lesão no circuito formado pelos núcleos denteado, rubro e olivar inferior (triângulo de Guillain e Mollaret). Pode ser secundária a hemorragias, trauma, neoplasias, entre outras causas que lesem estruturas desse circuito. Destaca-se a relevância deste relato de caso por apresentar um caso de degeneração olivar hipertrófica bilateral, secundária a insulto em ambos os núcleos denteados após ressecção de metástase.
Hypertrophic olivary degeneration represents the results of a lesionthat damages the neuronal connections between the dentate nucleus of the cerebellum, the red nucleus, and the inferior olivary nucleus (Guillain Mollaret triangle). This entity can occur secondary to hemorrhage, trauma, neoplasm and other causes that candamage structures of this pathway. This is an important case report because of its description of a bilateral hypertrophic olivary degeneration, secondary to injuries in both dentate nucleous after metastatic resection.

Renal cell carcinoma [RCC] is a tumor with high degree of potentiality for distant metastasis. Intracranial metastasis is a very rare location for this tumor. Here is presented a 47-year-old female with history of RCC and cerebellar metastasis

Cerebellar metastasis in a 70-year-old female is reported. She was admitted with a 1-month history of vertigo and unsteadiness of gait. There was no history suggestive of raised intracranial pressure. Except for cerebellar signs on right side, she had no other neurological deficit. Systemic examination revealed no abnormality except for a 3cm mobile lump under the nipple that was present for last 10 years without increasing in size. Computed tomography and magnetic resonance imaging of the head revealed a cystic tumour 3 x 3 cm diameter in right cerebellar hemisphere with a possible diagnosis of haemangioblastoma. The lesion was excised and she had an uneventful recovery. Histopathology revealed a metastatic carcinoma of the breast. After two months she underwent modified radical mastectomy. She received deep x-ray therapy for the brain and the breast. Follow-up 6 months later showed no neurological deficits or local recurrence
