Objective. The purpose of this series is to emphasize the importance of an exhaustive and appropriately conducted sonographic examination in the correct diagnosis of fetal cystic scalp lesions and the place of magnetic resonance imaging (MRI) in the diagnostic sequence. Methods. Transabdominal and transvaginal 2- and 3-dimensional sonography with color and power Doppler imaging as well as 3-dimensional rendering techniques such as inversion and Doppler angiography were used. In 1 case, an MRI study was performed. Results. In 1 case, the MRI missed and the different sonographic techniques correctly made the diagnosis of a meningocele. In the second case, sonography was sufficient to establish the diagnosis of an epidermal cyst. Conclusions. These 2 cases show the value of going the distance with the newly available high-frequency sonography. Ultimately, the correct diagnoses were made with the tools offered by sonography without the need for any other imaging modality.
