Abstract

A 30-year-old man presented with a fairly large intramedullary mass lesion involving virtually the entire spinal cord. It was hyperintense on both T1W and T2W sequences, with signal suppression on fat-saturation images. Subsequent noncontrast CT scan of the spine confirmed the presence of fat and calcification within the lesion, thus leading to the diagnosis of an intramedullary dermoid.

Figures

Figure 1 (A,B)
Figure 1 (A,B)
T1W (A) sagittal MRI image shows a heterogeneous intramedullary lesion (arrow) causing expansion of the conus medullaris region with hyperintense intramedullary signal (arrowhead) extending from the cervical to the lumbar regions. The sagittal T2W fat-saturation image (B) shows suppression of signal (arrow) in the upper spinal cord.
Figure 2 (A–C)
Figure 2 (A–C)
Sagittal T2W (A) and T1W (B) MRI images show a heterogeneous signal intensity mass (arrows) in the conus medullaris region with heterogeneous enhancement in the post-contrast T1W fat-saturation image (C).
Figure 3 (A–C)
Figure 3 (A–C)
Non-contrast sagittal CT scan reconstructed images show intramedullary fat (+) in the upper spinal cord (A) and a mass in the conus region (long arrow) with areas of fat (+) and calcification (short arrow) (B). Noncontrast axial CT scan (C) shows a focal area of calcification (arrow) within the lesion.
