Introduction: The pseudo-tumor cerebri (PTC) is defined as the idiopathic
or benign intracranial hypertension (IH), complaints of which cannot be
explained in a different way. PTC is an exclusion diagnosis, in which the
neuroophtalmopathology of IH cannot be determined. The patients with PTC may
have complaints such as headache, nausea, vomiting, temporary blurred vision, and
mild-level vision loss or unilateral or bilateral abducens nerve paralysis may develop.
The radiological examination of patients yields normal results. In case that IH
develops due to any reason, the enlargement is seen in optic nerve sheath
diameter (ONSD) in the acute period.

Case
reports: 14 year-old patient,
who has been diagnosed for PTC in our unit, optic nerve sheath diameter (ONSD)
measurement and follow-up of pressure change of whom have been performed by using
ultrasonography (USG) method, is presented in order to discuss the contribution
of this non-invasive method to diagnosis, treatment, and observation processes.

Conclusion: USG and ONSD
measurement in PTC cases may be effective and reliable monitoring method as
much as invasive methods.
