The growing teratoma syndrome (GTS) is defined as the development of mature low-grade elements in the absence of a recurrent non-germinomatous germ-cell tumor (NGGCT) after partial response to multimodal treatment. It is uncommon and may occur in intracranial NGGCTs. Here, we report that a 7-year-old boy with intracranial NGGCT presented with precocious puberty and developed growing teratoma syndrome only 2 weeks after the first cycle of chemotherapy.
