MRI features of sacrococcygeal teratoma in neonates

Abstract

Magnetic resonance is a crucial imaging modality in evaluation and classification of lower lumbar region masses, in our case sacrococcygeal teratoma (SCT). Sacrococcygeal teratoma is the commonest congenital tumor in fetuses and neonates. Sacrococcygeal teratomas are derived from all three germinal layers and arise from the ventral surface of the coccyx. The American Academy of Pediatrics’ Surgical Section (APPSS) classification helps in grading the extent of sacrococcygeal teratomas in four different types. The SCTs appear on MRI as hetero-signal, tumor-like masses of varying extent containing soft tissue, fat or liquid components. Treatment and further management depend profoundly on the type of SCT which is based on the exact MRI findings
