A 32-year-old woman (G2, P1) with non contributive history presented to our office at 16 week of gestation. Our investigation revealed a defect of the lumbar spine (spina bifida) with some cranial findings (lemon sign) accompanying the lumbar defect.

Images 1, 2: Image 1 shows an axial scan of the fetal skull with bifrontal deformity of the calvaria - "lemon sign" (arrows). The image 2 shows coronal scan of the fetal head demonstrating the bifrontal deformity of the calvaria accompanying the lumbar spina bifida.

Images 3, 4: Axial scans of the fetal abdomen at two different levels showing the opened defect of the spine.

Image 5: Coronal scan of the fetal lumbar spine showing the spina bifida.
