To describe an atypical clinical and radiological presentation of a brainstem epidermoid cyst in a child and to provide a review of the medical literature on brainstem epidermoid cysts in children. ⋯ Epidermoid cysts are rare tumors of the brain and children. The management of these tumors can be quite challenging. A good clinical and neuroradiological evaluation pre-operatively is fundamental for a successful surgical treatment. Surgical resection should be as radical as possible without putting the patient's neurological status into risk.

Arteriovenous malformations (AVMs) constitute malformative lesions of the central nervous system vasculature and cause significant morbidity and mortality. Endovascular embolization with n-butyl cyanoacrylate is a well established modality of AVM treatment, usually combined with surgery or radiosurgery. The purpose of this study was to characterise the AVMs that were treated endovascularly with n-butyl cyanoacrylate and to evaluate the post-embolization results in the Cuban population. ⋯ The rates of total occlusion and of morbidity and mortality in the series are in the internationally described ranges. The implementation of intranidal closings with 20-30% devascularization per session and the use of post-embolization hypotension after the haemorrhage complications described resulted in the total absence of haemorrhagic complications.
