Brief Summary

Cerebral cavernous malformation (CCM)-related epilepsy (CRE) impairs the quality of life in patients with CCM. Patients could not always achieve seizure freedom after surgical resection of the lesion, suggesting an inadequate treatment and evaluation of the epileptogenic zone or network. Iron deposition in cerebral cavernous malformations has been postulated to play an important role in triggering CRE. Quantitative susceptibility mapping (QSM), as an optimal in vivo imaging technique to quantify iron deposition, is employed to analyze the iron quantity in CCM patients with epilepsy and further combined with brain structural and connectome analysis, to describe the difference between CCMs with and without epilepsy. In vivo biomarkers predicting CRE risk in CCM natural history and CRE control outcome after CCM surgical resection will be further identified to improve management strategy.

Outcome Measures

Primary Outcomes (3)

  • Perilesional mean QSM in CCM with conservative treatment

    Each patient contributes five outcome measurements (at annual image of 5-year follow-up). Perilesional QSM measurements will be performed at baseline and at annual epoch of image. Perilesional mean QSM (in parts per million, ppm) in each study group will be evaluated using univariate comparison and a repeated measures analysis implemented as an unadjusted linear mixed model.

    End of study (5-year) MRI scan

  • Perilesional mean QSM after surgical resection of CCM lesion

    Each patient contributes three outcome measurements (at year 1 and 2 and 3 after surgery). Perilesional QSM measurements will be performed at annual imaging follow-up after surgery. Mean QSM (in parts per million, ppm) in patients with or without postoperative seizure will be evaluated using univariate comparison and a repeated measures analysis implemented as an unadjusted linear mixed model.

    End of study (3-year) MRI scan after surgery

  • Ratio of seizure freedom during follow-up

    Seizure freedom, defined as Engel Classification of Post-treatment Outcome Class I, will be assessed annually during follow-up period. For patients with medical treatment or conservative observation, the follow-up period begins since enrollment. For patients with surgical resection, the follow-up period begins after surgery.

    End of follow-up period (5-year)

Secondary Outcomes (2)

  • Grey matter volume in CCM with epilepsy

    End of study (5-year) MRI scan

  • Whole-brain connectome in CCM with epilepsy

    End of study (5-year) MRI scan

Study Arms (2)

Cerebral Cavernous Malformation with Epilepsy

Patients with cerebral cavernous malformation and associated with epilepsy will undergo MR imaging and be followed-up annually as our protocol defined.

Cerebral Cavernous Malformation without Epilepsy

Patients with cerebral cavernous malformation but without epilepsy will undergo MR imaging and be followed-up annually as our protocol defined.
