To examine recurrence rates in patients undergoing microsurgical excision of colloid cysts of the third ventricle with long-term serial clinical and imaging follow-up and to identify risk factors for cyst recurrence. ⋯ Periodic imaging surveillance is essential after excision of third ventricular colloid cysts to detect asymptomatic recurrences because these lesions may recur several years after presumed total or near-total excision. Recurrences associated with clinical symptoms or demonstrated growth on serial follow-up require intervention; however, reoperation may be cautiously deferred in patients with stable asymptomatic recurrences.

Assess the complications, clinical outcomes, and angiographic results of endovascular treatment (EVT) for ruptured intracranial posterior circulation aneurysms in small arteries, and identify their risk factors. ⋯ Reconstructive EVT for ruptured intracranial posterior circulation small artery aneurysms was generally safe and effective. However, the risk of complications and unfavorable clinical outcomes persisted. External ventricular drainage was a significant risk factor for in-hospital complications, whereas older age and higher World Federation of Neurosurgical Societies grades were predictors of unfavorable clinical outcomes.

The management of multiple intracranial aneurysms poses a significant clinical challenge.1 Various factors, including the patient's neurologic status, age, risk factors, aneurysm morphology, location, ruptured or unruptured status, availability of equipment, the surgeon's surgical abilities, and patient preferences, influence the choice of treatment modality.2 It has been observed that there is a higher risk of rupture during the perioperative period when surgical intervention is performed to treat a ruptured aneurysm.3 Additionally, it is suggested that patients with multiple aneurysms located in both the anterior and posterior circulation are less likely to be treated with a single procedure.4 This surgical strategy should be applied in the setting of multiple aneurysms in the anterior and posterior circulation that would, on the other hand, demand multiple interventions.5 In an experienced scenario, microsurgery could be a viable option. We present the case of a 58-year-old patient who presented with chronic headaches, a medical history of hypertension, and tobacco use. The patient had no neurologic deficits. ⋯ The patient consented to the procedure and publication of her image. No institutional research ethics board approval was required because only intraoperative footage was shown. No identifiable data are displayed except for 2 photographs of the patient's head without the face, which was appropriately consented to.

Trigeminal neuralgia is usually associated with vascular compression of the nerve entry zone. However, a dolichoectatic basilar artery represents the cause in only up to 3% of cases.1 This is characterized by dilation, elongation, or tortuosity of the vertebrobasilar arteries.2 In 10%-30% of cases, pain relief is not achieved with medical treatment. Thus, microvascular decompression techniques have been proven the most effective. ⋯ This surgical video illustrates anatomic nuances and critical aspects of the retrosigmoid approach as a safe and adequate access for microvascular decompression in a rare case of a megadolichoectatic basilar artery (Video 1). The patient consented to the procedure and the publication of his images. Institutional review board/ethics committee approval was not required nor sought due to the nature of this paper.
