Abstract
BACKGROUND

Posterior reversible encephalopathy syndrome (PRES), characterized by acute neurological deterioration and extensive white matter lesions on T2-fluid attenuated inversion recovery magnetic resonance imaging (MRI), is increasingly associated with calcineurin inhibitors (CNI)-related neurotoxicity. Prompt diagnosis is crucial, as early intervention, including the modification or discontinuation of CNI therapy, strict blood pressure management, corticosteroid treatment, and supportive care can significantly improve patient outcomes and prognosis. The growing clinical recognition of CNI-related PRES underscores the importance of identifying and managing this condition in patients presenting with acute neurological symptoms.

CASE SUMMARY

This report describes three cases of liver transplant recipients who developed PRES. The first case involves a 60-year-old woman who experienced seizures, aphasia, and hemiplegia on postoperative day (POD) 9, with MRI revealing ischemic foci followed by extensive white matter lesions. After replacing tacrolimus, her symptoms improved, and no significant MRI abnormalities were observed after three years of follow-up. The second case concerns a 54-year-old woman with autoimmune hepatitis who developed headaches, seizures, and extensive white matter demyelination on MRI on POD24. Following the switch to rapamycin and the initiation of corticosteroids, her symptoms resolved, and she was discharged on POD95. The third case details a 60-year-old woman with hepatocellular carcinoma who developed PRES, evidenced by brain MRI abnormalities on POD11. Transitioning to rapamycin and corticosteroid therapy led to her full recovery, and she was discharged on POD22. These cases highlight the critical importance of early diagnosis, CNI modification, and stringent management in improving outcomes for liver transplant recipients with CNI-related PRES.

CONCLUSION

Clinical manifestations, combined with characteristic MRI findings, are crucial in diagnosing PRES among organ transplant recipients. However, when standard treatments are ineffective or MRI results are atypical, alternative diagnoses should be taken into considered.

Core Tip: Liver transplantation is the only curative option for end-stage liver disease. The rise in liver transplants is accompanied by an increase in the occurrence of neurological complications. The etiology of calcineurin inhibitor (CNI)-related posterior reversible encephalopathy syndrome (PRES) remains unclear, and there are no established preventive measures. Optimal treatment strategies are still a matter of debate. CNIs, although widely used in liver transplants, come with various side effects. Therefore, when new neurological symptoms arise in liver transplant patients on CNIs who meet the diagnostic criteria for PRES, a cerebral magnetic resonance imaging should be promptly conducted to provide diagnostic evidence. Initiating treatment promptly upon confirming the diagnosis is essential for enhancing clinical outcomes.
