Cerebrospinal fluid leakage and ventricular compression during open surgery may lead to brain deformation called brain shift. Brain shift may affect intraoperative navigation that is based on image-based preoperative planning. Tools to correct or predict these anatomic modifications can be important to maintain precision during open guided neurosurgery. ⋯ CBCT, cone-beam computed tomographyHU, Hounsfield units.

Basilar fenestration aneurysms are rare, challenging intracranial vascular lesions with atypical anatomy. The posterior circulation represents a difficult therapeutic dilemma because of the close proximity of crucial life-sustaining brainstem structures. The use of flow diverter technology has been very limited in posterior circulation vessels. ⋯ AA, arachnoid acidADP, adenosine diphosphateFD, flow diverterMRA, magnetic resonance angiogramPED, Pipeline embolization deviceVBJ, vertebrobasilar junction.

Cerebrospinal fluid diversion is one of the most frequent neurosurgical procedures across the world and can be challenging in select patients who fail standard distal drainage sites. ⋯ SVC, superior vena cava.
