Antithrombin III deficiency and idiopathic intracranial hypertension: a case report.

backgroundIdiopathic intracranial hypertension (IIH) is a condition where the pressure of the cerebrospinal fluid in the brain increases without a known cause. It typically affects adults but can also occur in adolescents and children, although it is less common. Numerous elements, including coagulopathy, have been documented in previous cases as potential etiological factors of IIH. Nonetheless, our objective was to present the insufficiency of a coagulation factor as an additional contributing factor to IIH, a notion that has not been previously reported. CASE PRESENTATION: In this case, a 34-year-old West Asian female patient presented with a subacute generalized headache, bilateral blurred vision, and papilledema. The patient's brain magnetic resonance imaging showed flattening of the posterior globe and empty sella, but no other abnormalities were detected. The results of magnetic resonance venography and cerebrospinal fluid analysis were also normal, except for an opening cerebrospinal fluid pressure of 600 mm H

conclusionThis case highlights the importance of considering coagulopathy in cases of IIH and suggests that antiplatelet therapy with acetylsalicylic acid may be beneficial for such patients.
