[Medulloblastoma during pregnancy. Description of a case with extraneural metastases and review of the literature].

Medulloblastoma is a rare neoplasm in adults. Extraneural metastases from this tumor are an unusual event. Maternal malignancy during pregnancy is very uncommon, especially for brain tumors and particularly for medulloblastoma. We describe the eighth case of medulloblastoma discovered during pregnancy with subsequent metastases to the muscle and lymph nodes.
