INTRODUCTION Primary central nervous system lymphomas are infrequently occurring lymphomas that account for only 0.3-1.5% of all intra-cranial neoplasms in patients without acquired immune deficiency syndrome. However, a pure third ventricle lymphoma is extremely rare. Here, we discuss the similar radiological appearances of lesions localized in the third ventricle and the importance of accurat...

Colloid cysts comprise 0.5 to 1% of intracranial tumors that are most commonly diagnosed in third to fifth decade of life.1,2 These benign tumors are generally seen in the anterosuperior portion of the third ventricle and are by far the most common of the intraventricular masses here.3,4 Colloid cysts are of endodermal (foregut) origin and are lined by pseudostratified, cuboidal, or columnar ep...

OBJECTIVE Colloid cysts (IIIVT CC) are benign neuroepithelial cysts located in the anterior third ventricle. The authors propose the use of Nd:YAG laser stereotactic neuroendoscopic for guided resection of the third ventricle colloid cysts. METHOD Eleven patients presented third ventricle colloid cysts and were treated by Nd:YAG laser guided with stereotactic endoscopy (n=7) , stereotactic en...

Cases of sellar involvement of neurocysticercosis (NCC) are rare. Little is known about the mechanisms by which the parasite can compromise the pituitary gland. Although NCC damages sellar structures with direct compression by large cysts, extension through the basal cisterns and third ventricle with focal arachnoiditis can result as an inflammatory response. Evaluation for hypophyseal lesions ...

Introduction: Colloid cyst of the third ventricle is a rare intracranial benign tumor. Traditionally, treatment is carried out by transcallosal or transcortical transventricular approach. Currently, the endoscopic treatment of these lesions is increasingly used. We reported our preliminary experience about three cases of colloid cysts treated by neuroendoscopy. Methods and Patients: We condu...
