Dural ectasia of the optic nerve sheath.

Kacem HH, Hammani L, Ajana A, Nassar I - Pan Afr Med J (2014)

Bottom Line: Optic nerve dural ectasia is a rare cause of optic nerve sheath enlargement due to the accumulation of CSF around the optic nerve with no associated pathology.We describe the case of a 24-day-old female referred for a visual blurring, which we diagnosed as a dural ectasia of the optic nerve sheath by MRI and confirmed in surgical intervention.We present this case report to illustrate the classic imaging features of the disease.

ABSTRACT
Optic nerve dural ectasia is a rare cause of optic nerve sheath enlargement due to the accumulation of CSF around the optic nerve with no associated pathology. It diagnosed by MRI studies and can follow benign or sometimes an unfavorable course. We describe the case of a 24-day-old female referred for a visual blurring, which we diagnosed as a dural ectasia of the optic nerve sheath by MRI and confirmed in surgical intervention. We present this case report to illustrate the classic imaging features of the disease.

Figure 0002: Orbital MRI; Coronal view of T2-weighted MRI Hyperintense cerebrospinal fluid-intensity dilated sheath surrounding normal optic nerves (bull's eye)

Mentions: A magnetic resonance imaging (MRI) with fat-suppression and an off-axis, coronal and sagittal views were performed, a tubular-cystic enlargement of the optic nerve sheath was identified as containing a CSF (cerbrospinal fluid)-intensity lesion that was hyperintense on T2-weighted images (Figure 1, Figure 2). There was no evidence of tumor in the brain or orbit.
