Objective: The objective of this study is to present the rare case of a young girl with idiopathic intracranial hypertension secondary to hypoparathyroidism.Background: Idiopathic intracranial hypertension is a neurological syndrome characterized by elevated intracranial pressure (> 25 cmH2O) in the absence of intracerebral abnormalities or hydrocephalus. The pathophysiology of idiopathic intracranial hypertension is unknown, and rare cases of idiopathic intracranial hypertension secondary to hypoparathyroidism have been described. It is supposed that hypocalcemia causes decrease in the absorption of cerebrospinal fluid in arachnoidal granulations.Methods: The workup of the girl with idiopathic intracranial hypertension and hypoparathyroidism included physical examination, blood tests, diagnostic imaging, and lumbar puncture.Results: We present a 9-year-old female patient who was hospitalized for headache associated with nausea and vomiting for 3 weeks. She underwent an ophthalmologic examination that revealed papilledema. Lumbar puncture revealed an opening pressure of 65 cm H2O; cerebrospinal fluid analysis and brain computed tomography scan were normal. The patient started taking acetazolamide. Blood tests revealed hypocalcemia associated with high phosphorus level and undetectable PTH hormone, which led us to suspect hypoparathyroidism. She had never had cramps, paraesthesias, or tetany. Chvostek's and Trousseau's signs were positive. In the neck ultrasonography, parathyroids were not visible. Oral supplementation with calcitriol and calcium was started. Headache, nausea, and vomiting immediately disappeared after the lumbar puncture, and the papilledema improved gradually.Conclusions: Several anecdotal cases of idiopathic intracranial hypertension secondary to hypoparathyroidism have been described. However, our case report is of particular interest, since the child did not present with typical neurological hypoparathyroidism symptoms. Therefore, we recommend that hypoparathyroidism should be included in diagnostic investigations on children with clinical findings of idiopathic intracranial hypertension, because clinical manifestations of hypoparathyroidism are variable and may involve almost all organ systems.

Abstract Background Idiopathic intracranial hypertension (IIH) mainly affects overweight women in the middle age period. The pathophysiology of IIH stays unclear, but suggested mechanisms include excess CSF production, reduced CSF absorption, increased brain water content, and increased cerebral venous pressure Objectives To assess the cerebrospinal fluid (CSF) flow dynamic changes in aqueduct of Sylvius in patients of idiopathic intracranial hypertension (IIH) with new MRI technique: phase contrast cine MRI (PCC-MRI). Methods Thirty patients diagnosed with idiopathic intracranial hypertension were divided into 3 groups according to treatment options (no treatment, medical treatment, and medical treatment with repeated lumbar tapping). CSF flow data were evaluated by phase contrast cine MRI. Results PCC-MRI parameters were significantly higher in group who was on medical treatment (group II) than other groups. The sensitivity of PCC MRI parameters ranged from 56.7 (stroke volume (SV) and mean flow (MF)) to 83.3% (peak systolic velocity (PSV)). A statistically significant difference was found for the mean flow value (p 0.039) between the control group and IIH patients. Conclusion The most specific CSF flowmetry parameter detected to help diagnosis of IIH is mean flow especially among early discovered patients. PCC MRI can be used as non-invasive technique for diagnosis of IIH and treatment follow-up.

Abstract Background The presentation of idiopathic intracranial hypertension (IIH) in association with iron deficiency anemia (IDA) is rare. Case presentation This case report depicts the unusual case of a 31-year-old woman of mixed Jamaican and English heritage with IIH who presented initially as IDA in the context of menorrhagia. Subsequent ophthalmic review, lumbar puncture, cerebrospinal fluid analysis and neuroimaging studies revealed severe bilateral optic disc swelling and raised intracranial pressure in keeping with IIH. Prompt treatment of IDA with blood transfusion and orally administered iron supplements, in addition to medical treatment for IIH, contributed to significant improvement of symptoms and prevented long-term visual deficits. Conclusion The possibility of IDA, albeit rare, should always be considered and investigated appropriately in all patients with IIH, as the treatment of the anemia alone may be sight-saving.
