Abstract:
We report central pontine myelinolysis in orthotopic liver transplant patients. Sequential MR imaging of these patients with central pontine myelinolysis shows progressive decrease of T2-weighted MR signal in the pons, which may not resolve despite complete neurologic recovery.
Insights
Central pontine myelinolysis can occur in liver transplant recipients. Magnetic resonance imaging reveals a progressive signal decrease in the pons, which may persist even after neurological recovery.
Area of Science:
- Neurology
- Transplant Surgery
- Radiology
Background:
- Orthotopic liver transplantation (OLT) is a life-saving procedure.
- Central pontine myelinolysis (CPM) is a rare but serious neurological complication.
- Patients undergoing OLT are at risk for various post-transplant complications.
Purpose of the Study:
- To describe the magnetic resonance (MR) imaging findings of central pontine myelinolysis in patients following orthotopic liver transplantation.
- To characterize the evolution of MR imaging findings in CPM post-OLT.
- To correlate MR imaging findings with neurological recovery in this patient cohort.
Main Methods:
- Retrospective review of sequential MR imaging studies in patients diagnosed with CPM after OLT.
- Analysis of T2-weighted MR signal changes in the pons.
- Correlation of imaging findings with clinical neurological status.
Main Results:
- Central pontine myelinolysis was identified in a cohort of orthotopic liver transplant patients.
- Sequential MR imaging demonstrated a progressive decrease in T2-weighted signal within the pons in affected patients.
- This characteristic MR imaging finding of CPM may persist despite complete neurological recovery.
Conclusions:
- Central pontine myelinolysis is a relevant neurological complication in orthotopic liver transplant recipients.
- MR imaging is crucial for diagnosing and monitoring CPM, showing a characteristic progressive T2-weighted signal decrease in the pons.
- The persistence of MR imaging abnormalities does not necessarily preclude neurological recovery in OLT patients with CPM.
