  • Title: Trigonal cavernous angiomas: report of three cases and review of literature.
    Author: Kumar GS, Poonnoose SI, Chacko AG, Rajshekhar V.
    Journal: Surg Neurol; 2006 Apr; 65(4):367-71, discussion 371. PubMed ID: 16531197.
    Abstract:
    BACKGROUND: Intraventricular cavernous angiomas are very rare. Only few cases of trigonal angiomas have been reported. CASE DESCRIPTION: We report three cases of trigonal cavernous angiomas who presented with raised intracranial pressure or seizures and who underwent total excision with a good recovery. We also review the literature and discuss surgical approaches. CONCLUSION: On magnetic resonance imaging, intraventricular cavernous angiomas lack the hemosiderin ring characteristically seen around parenchymal cavernous angiomas. This explains why trigonal cavernous angiomas can mimic malignant neoplasm on imaging, and they should be considered in the differential diagnosis of intraventricular masses. Total excision should be the goal of surgery.
