Time-Spatial Labeling Inversion Pulse Magnetic Resonance Imaging of Cystic Lesions of the Spinal Cord.

Background: Cystic lesions of the spinal cord such as spinal intradural arachnoid cysts (SIACs) and spinal extradural arachnoid cysts (SEACs) contain cerebrospinal fluid (CSF). The pathology of these lesions is often difficult to understand because it is difficult to detect abnormal CSF flow by conventional magnetic resonance imaging (MRI) or myelography. We preliminarily evaluated the usefulness of time-spatial labeling inversion pulse magnetic resonance imaging (T-SLIP MRI) of cystic lesions of the spinal cord.

Detection of the communicating hole(s) of spinal extradural arachnoid cysts using time-spatial labeling inversion pulse magnetic resonance imaging.

Study Design: Report of 2 cases.

Objective: To report the usefulness of time-spatial labeling inversion pulse magnetic resonance imaging (T-SLIP MRI) for detection of the communicating hole(s) of spinal extradural arachnoid cysts (SEACs).

Summary Of Background Data: SEACs normally communicate with the subarachnoid space via small communicating hole(s) in the dura.
