Multiple intradural arachnoid diverticuli: the need for complete myelography.
A 12-year-old boy presented with enuresis, leg weakness, and lower extremity spasticity. An initial lumbar water-soluble contrast myelogram disclosed an arachnoid diverticulum. After the insertion of a cystopleural shunt, the patient improved and was dry. However, 2 months later the patient became enuretic and developed weakness. Repeat myelography showed a second arachnoid diverticulum located in the midthoracic region. This second diverticulum was treated by marsupialization of the cyst wall to the subfascial space. The authors stress the need for complete myelography in patients with intradural spinal arachnoid diverticuli and present a brief review of the literature.
