Symptomatic spine metastases are found in about 10% of patients with cancer. As the long-term survival of patients with carcinoma rises, the number of patients with symptomatic spine metastases is also increasing. In our tertiary referral center, patients usually present rapidly progressive neurologic disorders, which require an urgent treatment decision. Treatment options include extensive 360° stabilizations. These complex interventions are not always readily available. We examined the extent to which the patient population benefited from decompressive surgery without stabilization. We hypothesize that patients benefit from merely dorsal decompression, which preserves stability when they experience symptomatic spine metastases. ⋯ In our patient population, minimal intervention could significantly improve neurologic disorders. This outcome was seen over the whole study period. Even though different scoring systems suggest stabilization, our results show that spinal decompression alone might be indicated as well.

Giant serpentine aneurysms that occur in the distal anterior cerebral artery are extremely rare and challenging to manage because of their complex structure. In this case, we show an aneurysm resection performed after in situ side-to-side A3-A3 bypass to treat a giant serpentine distal anterior cerebral artery aneurysm. ⋯ Anterior cerebral artery giant serpentine aneurysms are rare and usually present with headache and mass effect. Aneurysm resection and distal flow protection are issues that we must consider. The sequential procedure of anastomosis and aneurysm resection is a feasible and safe option.

Bobble-head doll syndrome is a rare neurological syndrome presenting with repetitive anteroposterior head movements. It is usually associated with expansile cystic lesions in the third ventricular region. ⋯ Endoscopic ventriculo-cysto-cisternostomy is an effective, less-invasive technique in the treatment of suprasellar cysts that results in resolution of the bobbling head movements.

Intracranial aneurysms (IAs) located in the midline region represent formidable challenge owing to their deep location. The objective of this study was to assess feasibility and identify the limitations of endoscopic endonasal clipping of IAs. We further aimed to describe the locations and characteristics of aneurysms that may be amenable for endoscopic endonasal clipping; thus outlining the indications of these approaches. ⋯ Clipping of midline aneurysms of the posterior circulation is feasible via endoscopic endonasal approach. Small-sized ventrally and medially directed aneurysm models carried a better probability of getting proximal and/or distal control, as well as better overall ability to place a clip. The endonasal route seems to provide a limited condition for proper management of anterior circulation aneurysms.

In pediatric patients with moyamoya disease, the pathophysiology of transient neurological deficits and the clinical features of perioperative cerebral blood flow (CBF) changes are unclear. The purpose of this study was to investigate the risk factors of postoperative transient neurological deficits and identify predictors of perioperative CBF changes. ⋯ Brain compression by EMS is a risk factor for postoperative transient neurological deficits in pediatric patients with moyamoya disease, and preoperative CBF of the anterior MCA region could predict perioperative CBF change in the MCA regions.
