BACKGROUND: Gangliogliomas are rare tumors of the central nervous system. Intracerebral hemorrhage (ICH) is a frequent pathological event, rarely related to intracranial tumor. Here we report a cohort of 14 gangliogliomas, 3 of which were revealed by ICH. We also performed a systematic review of the literature on gangliogliomas revealed by ICH.
PATIENTS AND METHODS: We retrospectively collected data for all gangliogliomas operated on in our department between January 2015 and December 2019: clinical history, radiological data and outcome, with a special focus on gangliogliomas revealed by spontaneous ICH. All cases had pathological validation. For the systematic review, relevant studies were identified by systematic search of the scientific literature in PubMed.
RESULTS: Fifteen patients underwent surgery for ganglioglioma during the study period. Six cases were revealed by seizures, 3 by headache, 1 by hydrocephaly and 1 by developmental disorder. Three patients (21%) had hemorrhagic presentation. All patients were male, aged 30 to 48 years, diagnosed with atypical ICH without vascular abnormality on cerebral angiogram. Conservative management was first decided. Diagnosis of ganglioglioma was made within 3 months for 2 patients and 9 years later for 1, after surgical removal and histological analysis. All hemorrhagic gangliogliomas were BRAF wild type. The systematic review of the literature identified 8 other cases of ganglioglioma revealed by ICH.
CONCLUSION: ICH may be a mode of revelation of ganglioglioma, and ganglioglioma is a possible etiology of atypical ICH in young patients. Long-term imaging follow-up is mandatory in patients with unexplained ICH.
