Benign hydrocephalus in infants. A computed tomographic and clinical correlative study

Area of Science:

• Pediatric Neurology
• Neuroimaging
• Infant Development

Background:

• Benign hydrocephalus in infants is a condition characterized by enlarged head circumference and mild psychomotor delays.
• Computed tomography (CT) scans may show cerebrospinal fluid (CSF) space dilation, mimicking brain atrophy or subdural effusions.
• Distinguishing benign hydrocephalus from conditions requiring intervention is crucial for appropriate infant care.

Purpose of the Study:

• To investigate the clinical course and neuroimaging findings of benign hydrocephalus in infants.
• To compare the natural history of benign hydrocephalus with cases requiring surgical intervention (tapping or shunting) for subdural effusion or hematoma.

Main Methods:

• Clinical observation of 7 infants diagnosed with benign hydrocephalus over a 3-year period.
• Serial computed tomography (CT) scans to monitor cerebrospinal fluid (CSF) space changes.
• Comparison of clinical and imaging outcomes with a control group of infants with subdural effusion/hematoma.

Main Results:

• Infants with benign hydrocephalus demonstrated gradual, spontaneous normalization of both clinical symptoms and CT findings.
• No invasive procedures like tapping or shunting were required for the studied cohort.
• The observed recovery contrasts with the intervention-dependent outcomes in the control group.

Conclusions:

• Benign hydrocephalus in infants is a self-limiting condition with favorable prognosis.
• Conservative management and clinical observation are appropriate for infants presenting with macrocrania and mild psychomotor retardation due to benign hydrocephalus.
• Distinguishing this entity from subdural effusions requiring intervention is key to avoiding unnecessary procedures.
