Immature gastric teratomas are rare gastrointestinal tumors. Presented here are imaging findings of this neoplasm which was first seen via antenatal ultrasound. Subsequent fetal magnetic resonance imaging demonstrated a partially calcified mass that contained areas of diffusion restriction. Meconium pseudocyst was originally entertained as a differential consideration. Follow-up computed tomography and upper gastrointestinal fluoroscopy after delivery revealed a bilobed mass that was at least partially endogastric. Resection was performed, and the diagnosis was uncovered via histologic analysis.
