23-year-old male, status post previous resection of soft tissue tumors of the scalp and posterior cervical area.
There is kyphoscoliosis of the cervical spine. A homogenous intradural/extramedullary mass (Films 1 and 2) arises within the left side of a deformed spinal canal at the C1-C2 level, occupying almost the entire canal, displacing the cord to the right. Two large soft tissue masses are seen in the neck: one, well-defined in the C1-C4 prevertebral soft tissues (Films 3, 4, 5), the second, lobulated and less well- defined in the left posterior soft tissues extending from C1 to C7 with extension around the posterior elements of C1-C3. A gadolinium-enhanced study 8-1/2 months later shows enhancement of these masses (Films 4 and 5), each with different enhancing characteristics.
