Role of ultrasonography in comparison with computed tomography in the diagnosis of intracranial lesions in infancy

ABSTRACT

Ultrasonography is accurate in the diagnosis of hydrocephalus and intracranial cystic lesions and there is good correlation between C.T. and ultrasonography in the diagnosis of these lesions. After shunt operation, ultrasonography is essential for follow up of cases. Ultrasonography must be used as a screening method for examination of all pre-term infants because there is high incidence of intracranial hemorrhage in this age group. The portability of ultrasound units and the ability to perform scanning quickly with the patient inside the isolate are definite advantages as compared with C.T. Ultrasound is also very useful for detection and monitoring of complications of intracranial hemorrhage such as hydrocephalus. Real time ultrasonography is rapid, safe and effective method for diagnosing and evaluating the complications of meningitis. When a neoplasm is suspected on sonography, C.T. scan is recommended for more specific diagnosis
