Transfontanelle ultrasonography: an invaluable tool in the assessment of the infant brain.

Transfontanelle (cranial) ultrasonography was carried out in 98 Nigerian infants over a period of 5 years. Of the infants, 38 (38.8%) had hydrocephalus from various causes while 26 (25.5%) had congenital anomalies. As ultrasound equipment is becoming a more readily available and affordable tool in the developing countries, it should become much easier for medical staff in these countries to arrive at the correct diagnosis of intracranial diseases in infants.
