Symptomatic cerebral spinal fluid leak (or intracranial hypotension) due to sacral extradural cyst rupture after sacral fracture: illustrative case

SCs are rare entities that are often asymptomatic but should be carefully considered in the differential diagnoses for intracranial hypotension, even following low-impact trauma. Symptoms resolve with definitive treatment of dural tear, and recurrence rates are low. https://thejns.org/doi/10.3171/CASE2555.
