SUMMARY

Intracranial lipomas are rare, usually do not have clinical expression and are located mare frequently in the corpus callosum. Other locations include the spinal cord, midbrain tectum, superior vermis, tuber cinereum, infundibulum and more rarely cerebellopontine angle, hypothalamus, superior medullary velum and insula. We report the case of a lipoma of the left inferior colliculus which was a post-mortem finding in a woman who died of breast cancer. Although there are reports of intracranial lipomas in patients with malignant tumors there is no explanation for the co-existence of the two tumors. The present tumor also includes a segment of a nerve which is not uncommon, but a less common finding was the presence of nests of Schwann cells within it, shown by immunohistochemistry.


RESUMO

Lipomas intracranianos são raros, em geral sem expressão clínica, localizados mais freqüentemente no corpo caloso. Outras localizações incluem medula espinhal, teto mesencefálico, vermis superior, tuber cinereum, infundibulum e mais raramente o ângulo ponto-cerebelar, hipotálamo, véu medular superior e insula. Relatamos o achado de necrópsia de um lipoma do colículo inferior esquerdo em uma mulher com câncer de mama. Embora haja relatos de lipomas intracranianos em pacientes com tumores malignos não há explicação para a co-existência dos dois tumores. O presente tumor também inclui o segmento de um nervo, o que não é incomum, mas um achado menos comum foi a presença de ninhos de células de Schwann no tumor, mostradas por imuno-histoquímica.
