Large cavernous malformations in infant

Cavernous malformations are rare vascular malformations in the central nervous system. We present the case of a 2-month-old female patient who presented tonic-clonic seizures, with no previous history of seizures. Magnetic resonance imaging showed a 5.6 cm tumor in the left parieto-occipital region. The radiological aspect of the tumor initially suggested an anaplastic meningioma. After surgical treatment and anatomopathological analysis, it was found to be a cavernous malformation. Cavernous malformations, or cavernomas, are rare lesions and even more rare is the occurrence of large cavernomas. In the pediatric population, although still quite rare, they usually are presented as larger cavernomas. Surgical resection is considered the most effective treatment.
