Introduction: Introduction Causes of a bulging fontanel in children include viral/bacterial meningitis, encephalitis, hydrocephaly, intracranial bleeding, psedotumor cerebri and central nervous system tumors. A less well-known cause of acutely-developing fontanel bulging is transient intracranial hypertension.
Case report: A 7-month-old female was brought to our hospital with fever, cough, watery nasal secretion and bulging fontanel for the last 3 days. The cranial ultrasound examination and cerebrospinal fluid examinations were normal. The patient's irritability and fontanel bulging improved the day after admission but a maculopapular rash developed. The measles Ig M was positive. Measles PCR was positive from urine and nasopharyngeal swab samples. The signs of intracranial hypertension of the patient recovered completely the day after admission and did not recur during the follow-up. The patient was discharged on the 5th day of admission.
Discussion: Transient intracranial hypertension is thought to result from a transient increase in the quantity of the circulating cerebrospinal fluid but the pathogenesis is not clear.
Conclusions: Based on this case, we report that transient intracranial hypertension could develop during a measles infection.
