Serial MR imaging revealed spinal cord swelling and T2 signal changes in a patient with decompression sickness. These findings resolved over two months, suggesting MR imaging

Area of Science:

  • Neurology
  • Radiology
  • Diving Medicine

Background:

  • Decompression sickness (DCS) can affect the spinal cord, leading to neurological deficits.
  • Early and accurate diagnosis of spinal DCS is crucial for timely treatment and improved outcomes.

Observation:

  • A patient with suspected spinal decompression sickness underwent serial magnetic resonance (MR) imaging.
  • Imaging was performed at acute, 1-month, and 2-month follow-up intervals.

Findings:

  • Acute phase: MR imaging demonstrated spinal cord swelling with increased T2 signal in the posterior columns.
  • 1-month follow-up: Marked contrast enhancement was observed in the affected posterior spinal cord region.
  • 2-month follow-up: Resolution of spinal cord swelling and decreased T2 signal were noted.

Implications:

  • Serial MR imaging can track the evolution of spinal cord changes in decompression sickness.
  • These findings highlight the utility of MR imaging in the early diagnosis and management of spinal DCS.
  • Understanding the imaging characteristics of spinal DCS aids in differentiating it from other myelopathies.
