Surgical treatment of functional single-ventricle heart disease with a modified Fontan procedure results in elevated central venous pressure. The case report describes a 19-year-old boy with hypoplastic left heart syndrome and Fontan palliation that resulted in frequent debilitating headaches after transcatheter closure of systemic venous-to-pulmonary venous collaterals. Measured increased intracranial pressure and prompt relief of the headaches with lumbar puncture favored a diagnosis of pseudotumor cerebri. After implantation of a lumboperitoneal shunt, the patient's headaches improved dramatically. Headaches are frequent in patients with Fontan circulation. The current literature supports a pivotal role of elevated dural venous sinus pressure in the pathogenesis of pseudotumor cerebri. The high superior and inferior vena caval pressures characteristic of modified Fontan anatomy may account for headaches in some of these patients.

Purpose: To report the case of a woman in her fifties whose presenting symptom of idiopathic intracranial hypertension was engorgement of the eyelid veins.
Observations: Bilateral engorged palpebral veins were visible through the skin. Dilated fundus examination revealed bilateral optic disc edema.

Introduction: Managing idiopathic intracranial hypertension (IIH) is challenging due to limited treatment options. This study evaluates metformin as a potential therapy for IIH, examining its impact on disease outcomes and safety.
Methods: We performed a retrospective cohort study using the TriNetX database, covering data from 2009 to August 2024.

Background: Idiopathic intracranial hypertension (IIH) is increasingly prevalent, yet longitudinal outcome data are scarce. This study aimed to characterise demographic and longitudinal clinical changes in a cohort of patients with IIH.
Methods: Retrospective cohort analysis on adult patients diagnosed with IIH (Friedman criteria) enrolled in the neuro-ophthalmology database (NODE) across two tertiary centres.

The most common diagnostic error of IIH is inaccurate funduscopic examination. Moreover, IIH could be diagnosed without papilledema. Trans orbital sonography could be used as a non-invasive and cheap tool for discovering increased ICP (intracranial Pressure).

We discuss a case of a 19-year-old female who presented with pressure headaches and progressive vision loss. In the emergency department, a series of diagnostic tests were conducted, including CT, MRI, and lumbar puncture with measurement of opening pressure. All these examinations yielded results consistent with the suspected diagnosis of idiopathic intracranial hypertension (IIH).
