A CASE OF TRANSIENT CEREBROSPINAL FLUID HYPOVOLEMIA CAUSED BY A SACRAL CYST RUPTURE ASSOCIATED WITH SACRAL FRACTURE

Abstract

　　We experienced a rare case in which a patient exhibited cerebrospinal fluid hypovolemia due to liquorrhea from sacral fracture and sacral cyst rupture following trivial trauma, and it was resolved with conservative treatment. A 68-year-old female visited our hospital on foot with a complaint of hip pain due to a fall. Diagnostic imaging revealed a cyst in the sacral spinal canal ; the cyst compressed the sacrum, and it had become thinner and fractured. It also showed cerebrospinal fluid leakage caused by the cyst rupture. Orthostatic headache with nausea and dizziness lead to a diagnosis of cerebrospinal fluid hypovolemia caused by liquorrhea. Although cerebrospinal fluid leakage had markedly increased on the following day, orthostatic headache gradually subsided with conservative treatment. On the 8th day, cerebrospinal fluid leakage had almost disappeared. Thereafter, she was gradually getting out of bed without any relapse of symptoms, and discharged in remission on the 21st day.
