Lipomyeloschisis associated with thoracic syringomyelia and Chiari I malformation.

Co-existence of Chiari I malformation and myelomeningocele is uncommon. Syringomyelia, when associated with a Chiari I malformation, classically involves the cervical spinal cord. Intramedullary extension of lipoma is unusual in lipomyeloschisis.

A desmoid tumor was found in a patient with Gardner's syndrome. The tumor was visualized by CT before and after contrast injection, by radiographic examination of the small bowel, and by sonography. CT demonstrated a heterogeneous mass in the left lower abdomen with attenuation values ranging from 23 to 72 HU on native scans, enhancing to 123 up to 172 HU after injection of contrast medium.
