Description
Summary:A case of massive intracranial immature teratoma in a female stillborn is reported. She was the product of the second pregnancy of a 25-year-old healthy woman. The pregnancy was unremarkable until the 25th week of gestation when the mother noticed a rapid enlargement of her abdomen and intense pelvic pain. Because of the pain, a cesarean section was indicated, and a stillborn weighing 2750g with macrocephaly was delivered. The cranial contents weighed 1350g and showed a huge tumoral mass with only a rim of normal brain. A histologic diagnosis of immature teratoma was made. Massive intracranial teratomas are rare tumors and their occurrence in intrauterine life is even rarer. Their histogenesis is unknown, and there is no explanation for their continuous growth during embryogenesis. A prenatal diagnosis of this rare condition can be made by ultrasound, computed tomography, or magnetic resonance imaging.<br>Um caso de teratoma imaturo gigante do sistema nervoso central em um natimorto é relatado. Durante a gravidez, a mãe desenvolveu poli-hidrâmnio abrupto na 25ª semana de gestação e dor pélvica intensa, que levou a indicação de cesárea. O natimorto pesava 2750g, apresentava macrocefalia evidente e o conteúdo craniano pesou 1350g. Este era representado por tecido tumoral em sua maioria e apenas uma pequena rima de tecido encefálico normal. A histologia mostrou tratar-se de um teratoma imaturo. Teratomas intracranianos gigantes congênitos são neoplasias raras, de histogênese incerta e não há explicação para o crescimento contínuo e rápido durante a vida intra-uterína. O diagnóstico pré-natal pode ser realizado por ultra-sonografia, tomografía computadorizada ou ressonância magnética.
