Highlights Only 15 cases of clinically diagnosed hemorrhagic colloid cysts were reported in the literature and 5 more cases on autopsy. The benefits of excellent visualization and minimally invasive access through the dilated ventricular system are offered by the endoscopic approach. Open microsurgical technique is the best choice for hemorrhagic colloid cysts.

Background Various complications of endoscopic third ventriculostomy (ETV) have been described. One has to recognize these complications and learn how to avoid them. Methods We performed a literature review regarding the reported complications of ETV procedures discussed in a correlated manner with the surgical steps. Furthermore, we reviewed the technical notes described by experienced neuroendoscopists, including surgical indications, choice of the endoscopic entry point and trajectory, anatomic orientation, proper bleeding control and tight closure, to prevent and deal with such complications. Results and conclusion A lesson learned that comprehensive knowledge of ventricular anatomy with proper orientation by studying the preoperative images is mandatory and one should be aware of all complication types and rates.

Posterior approach lumbar disc surgeries (LDS) can be associated with serious iatrogenic vascular complications which could be a serious life threatening condition. We report a rare case of right sided acute iliac vessels iatrogenic arteriovenous fistula (IAVF) which was diagnosed and managed in 24 hours duration in a 45 years old healthy female who underwent surgical posterior approach L4-5 discectomy. Intraoperative, she developed sudden hypotension, tachycardia, wide pulse pressure and acute drop of hemoglobin level without obvious operative site bleeding which raise the index of suspicion of vascular injury and urge the team for doing emergency CT angiography (CTA), vascular and endovascular team consultation for digital subtraction angiography (DSA) and endovascular management. Endovascular stenting is nowadays the modality of choice of intervention. We provide case report with literature review.

Cerebral myiasis is extremely rare, and surgical intervention is the primary treatment used. Successful conservative management alone, without surgical removal of the brain infestation has not yet been published. We report the a case of a 24-year-old African homeless man who was found on the street in a state of decreased level of consciousness, with larvae exiting from the left supra and postauricular dirty wounds and from his left ear. The patient was diagnosed with post-traumatic cerebral myiasis of the left temporal lobe and cerebellum. It was treated successfully by debridement of the external wounds and administration of antibiotics, without surgical removal of the brain infestations. For the first time, this case illustrates the novelty and appropriateness of the conservative management of cerebral myiasis. This is also the first report of cerebral myiasis with cerebellar involvement and the second report of post-traumatic cerebral myiasis in literature. Continuous...
