RESUMEN
Occipital encephaloceles are the most common type of encephalocele encountered in the Western Hemisphere. The occipital encephalocele is typically classified according to the relationship of the herniated tissue to the torcular. We report the unusual case of a premature infant with a rare, large occipital encephalocele which encompassed the posterior superior sagittal sinus and torcular. We discuss the variable venous anatomy with occipital encephaloceles and review the different options to employ in their surgical repair.

We describe a rare complication of myelography. A subarachnoid filling defect was apparent on the postmyelographic CT but not on conventional myelography. MR imaging performed later showed a spinal subarachnoid hematoma (SSAH), extending from L3 to L5. Lumbar puncture may rarely be a cause for SSAH and is more common in patients with coagulopathy. Significant back pain, paresis, radiculopathy, and even altered consciousness or meningeal signs may herald an SSAH.
