31.1 Case Presentation

A 16-year-old female patient with history of a motor vehicular collision presents with complaint of neck pain and thoracic region back pain.

31.2 Imaging Analysis

Spine MRI from a 16-year-old female patient with sagittal T2-wighted (T2w; ▶ Fig. 31.1a), sagittal T1-weighted (T1w; ▶ Fig. 31.1b), and axial T2w (▶ Fig. 31.1c) images. A slightly enlarged central canal is noticed (arrows); however, there are no additional abnormalities of the spinal cord in course, overall diameter, or surrounding parenchymal signal intensity.

31.3 Differential Diagnosis

  • Prominent central canal:

    • This refers to a slightly expanded central canal filled with cerebrospinal fluid (CSF) without any spinal cord signal abnormality or enhancement.

  • Cystic spinal cord neoplasm:

    • The imaging hallmarks are cord signal abnormality, mass effect, contrast enhancement, and associated with neurological symptoms. 1

  • Syringohydromyelia:

    • Cystic dilatation of the central canal that could be isolated or associated with congenital anomalies in up to 30% of cases. 1

    • The entire spine MRI should be performed to rule out low-lying cerebellar tonsils (Chiari I malformation) as well as low-lying conus with or without fatty filum (tethered cord).

  • Myelomalacia:

    • Cord atrophy secondary to previous vascular, traumatic, or other injury.
