Unusual presentations of hydatidosis of the central nervous system

Abstract

This chapter describes unusual locations of hydatidosis of the central nervous system and has the purpose of showing the clinician that hydatid disease can manifest itself through various clinical characters that are out of the ordinary. The forms of hydatid disease we will present in this chapter require a great neurosurgical experience in order to achieve the best management and results. They have been gathered from all the literature in a single chapter and are both our personal experience and that of others, united to create a wider picture of this challenging pathology. We focus our attention on hydatid disease positioned in the ventricles, in the cerebellum, in the brainstem and in the orbit. We will also present extremely rare hydatid disease locations such as extrameningeal or extradural, intrameningeal, submeningeal, intracranial and intravertebral, or intraosseous, cisternal, and sinusal with reference to the vascular sinuses, thalamus, and brainstem.
