Giant Cavernous Malformations in Childhood: A Case Report and Review of the Literature.

Cavernous malformations (CMs) of the central nervous system are benign, angiographically occult vascular lesions and are diagnosed by magnetic resonance imaging techniques. Giant CMs do not differ from smaller-sized CMs in their clinical, surgical or histopathological presentation but may be radiologically different. In this paper, we report a 10-year-old male with a giant CM of 8 × 7.5 × 7 cm in diameter that was completely removed by microsurgical treatment. This case addresses important points for practicing neurosurgeons to consider when making a differential diagnosis of large intracranial mass lesions in pediatric patients. In this report, the radiological features of this vascular malformation are described based on a pertinent literature review.
