Meningeal Melanomatosis with a Spinal Meningeal Melanocytoma Trigger by an in vitro Fertilization.

Meningeal melanomatosis is an infrequent tumor originating from the melanocytes in the leptomeninges and one of the recognized primary melanocytic tumors of the central nervous system. The average survival has known to be about 5 months. It can be associated with solid tumors, such as meningeal melanocytomas. The patient we present was diagnosed of a meningeal melanomatosis that developed two solid tumors related to an in vitro fertilization. The clinical course was rapidly fatal. Although the use of comprehensive diagnostic procedures, usually the final diagnosis of primary diffuse meningeal melanomatosis is postmortem, it would be advisable for the appropriate management of the patient to make a differential diagnosis and to be aware of the behavior of the tumor.
