Prenatal diagnosis of occipital dermal sinus associated with hemangioma using ultrasound and MRI. Case report.
OBJECTIVE
We report a case of prenatal diagnosis and postpartum management of a subcutaneous tumor without intracranial communication.


METHODS
An occipital tumor without intracranial communication was found on ultrasound scan in the 21st week of pregnancy. Using MRI, the diagnosis was confirmed. Subcutaneous localization of the tumor was verified and communication with intracranial space excluded.


RESULTS
The newborn was delivered spontaneously at term and underwent a successful surgical procedure 5 months postpartum.


CONCLUSIONS
The prenatal diagnosis allowed differentiation between a communicating neural tube defect with poor prognosis, and a manageable extracranial subcutaneous tumor. The precise diagnosis of uncomplicated dermal sinus was possible only after the histological evaluation of the tumor confirmed occipital dermal sinus associated with hemangioma.
