VP24.05: Prenatal diagnosis and postnatal pathohistological verification of mature teratoma

Brain tumours diagnosed in fetal period are very rare incidents and the majority of them are represented by teratoma. As a rule, massive teratomas have a poor prognosis. We report a case of huge intracranial tumour with compressive mass effect without obstructive hydrocephalus at 32 weeks of gestation. For the second opinion the pregnant woman from one of the regions was referred to our clinic to a medical expert with suspicious of schisencephaly. Fetal neurosonography revealed fairly multiseptate cystic mass which shifted the left hemisphere up and to the right without obstruction of the CFS. Next the fetal MRI was performed and our diagnosis was mature teratoma (differential diagnosis supratentorial arachnoid cyst). Family decided to continue the pregnancy. At the 4th month the head circumference of the child grew very rapidly and as a result he developed the hydrocephalus. Baby undergone the operation and our diagnosis – mature teratoma was pathohystologically confirmed. Nowadays the baby is quite well and under the supervision of the doctor. Although the vast majority of teratomas has a poor prognosis in our case the outcome was favourable. Pathohystological verification is a very important tool that helps to confirm the diagnosis done by MRI.
