Suboccipital trans-horizontal fissure approach for cerebellar hemorrhage with rupture into the upper fourth and third ventricles: the first clinical experience. Illustrative cases

Ryota Tamura, Makoto Katayama, Yuki Kuranari, and Takashi Horiguchi

penetration of the SMV, the upper fourth ventricle packed with hematoma can be directly visualized ( 3 ). Hematoma in the upper fourth ventricle is removed. Dorsal brainstem is observed ( 4 ). Hematoma in the middle fourth ventricle is removed (caudal microscope direction) ( 5 ). Aqueduct is clearly identified (cranial microscope direction) ( 6 ). The third ventricle packed with blood clot is seen through aqueduct ( 7 ). Obstructive hydrocephalus is resolved by irrigation of the hematoma in the third and fourth ventricles. Fornix, superior choroidal vein, and choroid plexus

Lateral ventricle subependymoma resected with a transcallosal approach: illustrative case

Franco Rubino, Michael P. Catalino, Romulo A. Andrade de Almeida, and Sujit S. Prabhu

characteristics of the tumor infiltrating the ependyma over the basal ganglia or fornix and the continuous use of brain retractors to reach the lateral ventricle. 7 , 8 Conversely, the highest rates of severe postoperative complications have been reported in subependymomas located in the posterior fossa. 6 , 9 In this report, we present the case of a 65-year-old male with a subependymoma located in the left lateral ventricle. The tumor was completely resected using an interhemispheric transcallosal approach. Illustrative Case History and Presentation A 65-year

The infundibulochiasmatic angle and the favorability of an endoscopic endonasal approach in type IV craniopharyngioma: illustrative case

Guilherme Finger, Maria Jose C Ruiz, Eman H Salem, Matthew D Marquardt, Kyle C Wu, Lucas P Carlstrom, Ricardo L Carrau, Luciano M Prevedello, and Daniel M Prevedello

significant experience with the EEA and work within a multidisciplinary team familiar with the anatomy of the suprasellar region and third ventricle to safely perform this approach ( Fig. 5 ). The floor of the third ventricle extends from the optic chiasm anteriorly to the sylvian aqueduct posteriorly. The anterior wall of the third ventricle is formed by the anterior column of the fornix, anterior commissure, and lamina terminalis. 6 This approach is adjacent to many important structures, including the optic chiasm, infundibulum, tuber cinereum, mammillary bodies
