Steroid pulse therapy of radiological disease activity without clinical relapse in CLIPPERS

Diagnostic challenges in SLIPPERS syndrome: Case report

Background

SLIPPERS (Supratentorial Lymphocytic Inflammation with Parenchymal Perivascular Enhancement Responsive to Steroids) is a rare variant of a syndrome called CLIPPERS (Chronic Lymphocytic Inflammation with Ponsine Perivascular Enhancement Responsive to Steroids). SLIPPERS is characterized by distinct supratentorial lesions that share radiological and pathological characteristics with CLIPPERS. The ongoing issue is whether these syndromes should be considered as a distinct disease entity or simply a form for a variety of underlying conditions such as granulomatosis, vasculitis, and infectious diseases.

Case

We present a unique case of SLIPPERS observed in a 26-year-old woman with no notable medical or familial background. Laboratory findings ruled out certain diseases from the list of differentials and cranial MRI showed T2 hyperintense areas with linear-patchy enhancements, a pattern consistent with SLIPPERS syndrome. Consequently, patient was diagnosed with SLIPPERS syndrome and received methylprednisolone therapy.

Conclusion

Both SLIPPERS and CLIPPERS are complicated syndromes posing diagnostic challenges and requiring careful investigation to avoid misdiagnosis. Following a thorough differential diagnosis, appropriate treatment can be initiated, and follow-up is required.
