Case in brief
Seven patients with spontaneous intracranial hypotension (SIH) were initially misdiagnosed with Chiari malformation type I and underwent posterior fossa decompression. Following the procedure, five patients experienced temporary symptom relief, while six developed rebound intracranial hypertension. This case highlights the diagnostic challenges associated with SIH and the potential consequences of misdiagnosis.
Diagnostic / clinical pearl
Clinicians should consider spontaneous intracranial hypotension in patients with low-lying cerebellar tonsils to avoid unnecessary surgical interventions.
Why it matters
Misdiagnosis of SIH as Chiari malformation can lead to inappropriate treatments and complications, underscoring the need for careful evaluation of symptoms and imaging findings.
