Cerebrospinal Fluid Leakage After Lumbar Puncture in Neonates: Incidence and Sonographic Appearance

Abstract

Cerebrospinal fluid leakage into the epidural space is a frequent complication of lumbar puncture in neonates and has a characteristic appearance on sonograms. Leakage after lumbar puncture must be differentiated from cerebrospinal fluid leakage due to perinatal meningeal injury. If cerebrospinal fluid leakage at the puncture site compresses the subarachnoid space, sonography assists in the performance of subsequent lumbar puncture.
